Petitioner was charged with committing armed robbery and murder on the basis of evidence that he had killed and robbed two men. At the trial stage of Georgia's bifurcated procedure, the jury found petitioner guilty of two counts of armed robbery and two counts of murder. At the penalty stage, the judge instructed the jury that it could recommend either a death sentence or a life prison sentence on each count; that it was free to consider mitigating or aggravating circumstances, if any, as presented by the parties; and that it would not be authorized to consider imposing the death sentence unless it first found beyond a reasonable doubt (1) that the murder was committed while the offender was engaged in the commission of other capital felonies, viz., the armed robberies of the victims; (2) that he committed the murder for the purpose of receiving the victims' money and automobile; or (3) that the murder was "outrageously and wantonly vile, horrible and inhuman" in that it "involved the depravity of [the] mind of the defendant." The jury found the first and second of these aggravating circumstances and returned a sentence of death. The Georgia Supreme Court affirmed the convictions. After reviewing the trial transcript and record and comparing the evidence and sentence in similar cases the court upheld the death sentences for the murders, concluding that they had not resulted from prejudice or any other arbitrary factor and were not excessive or disproportionate to the penalty applied in similar cases, but vacated the armed robbery sentences on the ground, inter alia, that the death penalty had rarely been imposed in Georgia for that offense. Petitioner challenges imposition of the death sentence under the Georgia statute as "cruel and unusual" punishment under the Eighth and Fourteenth Amendments. That statute, as amended following Furman v. Georgia, 408 U.S. 238 (where this Court held to be violative of those Amendments death sentences imposed under statutes that left juries with untrammeled discretion to impose or withhold the death penalty), retains the death penalty for murder and five other crimes. Guilt or innocence is determined in the first stage [428 U.S. 153, 154] of a bifurcated trial; and if the trial is by jury, the trial judge must charge lesser included offenses when supported by any view of the evidence. Upon a guilty verdict or plea a presentence hearing is held where the judge or jury hears additional extenuating or mitigating evidence and evidence in aggravation of punishment if made known to the defendant before trial. At least one of 10 specified aggravating circumstances must be found to exist beyond a reasonable doubt and designated in writing before a death sentence can be imposed. In jury cases, the trial judge is bound by the recommended sentence. In its review of a death sentence (which is automatic), the State Supreme Court must consider whether the sentence was influenced by passion, prejudice, or any other arbitrary factor; whether the evidence supports the finding of a statutory aggravating circumstance; and whether the death sentence "is excessive or disproportionate to the penalty imposed in similar cases, considering both the crime and the defendant." If the court affirms the death sentence it must include in its decision reference to similar cases that it has considered. Held: The judgment is affirmed. Pp. 168-207; 220-226; 227.

Judgment of the Court, and opinion of MR. JUSTICE STEWART, MR. JUSTICE POWELL, and MR. JUSTICE STEVENS, announced by MR. JUSTICE STEWART.
The issue in this case is whether the imposition of the sentence of death for the crime of murder under the law of Georgia violates the Eighth and Fourteenth Amendments.
The petitioner, Troy Gregg, was charged with committing armed robbery and murder. In accordance with Georgia procedure in capital cases, the trial was in two stages, a guilt stage and a sentencing stage. The evidence at the guilt trial established that on November 21, 1973, the petitioner and a traveling companion, Floyd Allen, while hitchhiking north in Florida were picked up by Fred Simmons and Bob Moore. Their car broke down, but they continued north after Simmons purchased another vehicle with some of the cash he was carrying. While still in Florida, they picked up another hitchhiker, Dennis Weaver, who rode with them to Atlanta, where he was let out about 11 p. m. [428 U.S. 153, 159] A short time later the four men interrupted their journey for a rest stop along the highway. The next morning the bodies of Simmons and Moore were discovered in a ditch nearby.
On November 23, after reading about the shootings in an Atlanta newspaper, Weaver communicated with the Gwinnett County police and related information concerning the journey with the victims, including a description of the car. The next afternoon, the petitioner and Allen, while in Simmons' car, were arrested in Asheville, N.C. In the search incident to the arrest a .25-caliber pistol, later shown to be that used to kill Simmons and Moore, was found in the petitioner's pocket. After receiving the warnings required by Miranda v. Arizona, 384 U.S. 436 (1966), and signing a written waiver of his rights, the petitioner signed a statement in which he admitted shooting, then robbing Simmons and Moore. He justified the slayings on grounds of self-defense. The next day, while being transferred to Lawrenceville, Ga., the petitioner and Allen were taken to the scene of the shootings. Upon arriving there, Allen recounted the events leading to the slayings. His version of these events was as follows: After Simmons and Moore left the car, the petitioner stated that he intended to rob them. The petitioner then took his pistol in hand and positioned himself on the car to improve his aim. As Simmons and Moore came up an embankment toward the car, the petitioner fired three shots and the two men fell near a ditch. The petitioner, at close range, then fired a shot into the head of each. He robbed them of valuables and drove away with Allen.
A medical examiner testified that Simmons died from a bullet wound in the eye and that Moore died from bullet wounds in the cheek and in the back of the head. He further testified that both men had several bruises [428 U.S. 153, 160] and abrasions about the face and head which probably were sustained either from the fall into the ditch or from being dragged or pushed along the embankment. Although Allen did not testify, a police detective recounted the substance of Allen's statements about the slayings and indicated that directly after Allen had made these statements the petitioner had admitted that Allen's account was accurate. The petitioner testified in his own defense. He confirmed that Allen had made the statements described by the detective, but denied their truth or ever having admitted to their accuracy. He indicated that he had shot Simmons and Moore because of fear and in self-defense, testifying they had attacked Allen and him, one wielding a pipe and the other a knife. 1
The trial judge submitted the murder charges to the jury on both felony-murder and nonfelony-murder theories. He also instructed on the issue of self-defense but declined to instruct on manslaughter. He submitted the robbery case to the jury on both an armed-robbery theory and on the lesser included offense of robbery by intimidation. The jury found the petitioner guilty of two counts of armed robbery and two counts of murder.
At the penalty stage, which took place before the same jury, neither the prosecutor nor the petitioner's lawyer offered any additional evidence. Both counsel, however, made lengthy arguments dealing generally with the propriety of capital punishment under the circumstances and with the weight of the evidence of guilt. The trial judge instructed the jury that it could recommend either a death sentence or a life prison sentence on each count. [428 U.S. 153, 161] The judge further charged the jury that in determining what sentence was appropriate the jury was free to consider the facts and circumstances, if any, presented by the parties in mitigation or aggravation.
Finally, the judge instructed the jury that it "would not be authorized to consider [imposing] the penalty of death" unless it first found beyond a reasonable doubt one of these aggravating circumstances:
The Supreme Court of Georgia affirmed the convictions and the imposition of the death sentences for murder. 233 Ga. 117, 210 S. E. 2d 659 (1974). After reviewing the trial transcript and the record, including the evidence, and comparing the evidence and sentence in similar cases in accordance with the requirements of Georgia law, the court concluded that, considering the nature of the crime and the defendant, the sentences of death had not resulted from prejudice or any other arbitrary factor and were not excessive or disproportionate to the penalty applied in similar cases. 2 The death [428 U.S. 153, 162] sentences imposed for armed robbery, however, were vacated on the grounds that the death penalty had rarely been imposed in Georgia for that offense and that the jury improperly considered the murders as aggravating circumstances for the robberies after having considered the armed robberies as aggravating circumstances for the murders. Id., at 127, 210 S. E. 2d, at 667.
We granted the petitioner's application for a writ of certiorari limited to his challenge to the imposition of the death sentences in this case as "cruel and unusual" punishment in violation of the Eighth and the Fourteenth Amendments. 423 U.S. 1082 (1976).
Before considering the issues presented it is necessary to understand the Georgia statutory scheme for the imposition of the death penalty. 3 The Georgia statute, as amended after our decision in Furman v. Georgia, 408 U.S. 238 (1972), retains the death penalty for six categories of crime: murder, 4 kidnaping for ransom or where [428 U.S. 153, 163] the victim is harmed, armed robbery, 5 rape, treason, and aircraft hijacking. 6 Ga. Code Ann. 26-1101, 26-1311, 26-1902, 26-2001, 26-2201, 26-3301 (1972). The capital defendant's guilt or innocence is determined in the traditional manner, either by a trial judge or a jury, in the first stage of a bifurcated trial.
If trial is by jury, the trial judge is required to charge lesser included offenses when they are supported by any view of the evidence. Sims v. State, 203 Ga. 668, 47 S. E. 2d 862 (1948). See Linder v. State, 132 Ga. App. 624, 625, 208 S. E. 2d 630, 631 (1974). After a verdict, finding, or plea of guilty to a capital crime, a presentence hearing is conducted before whoever made the determination of guilt. The sentencing procedures are essentially the same in both bench and jury trials. At the hearing:
In the assessment of the appropriate sentence to be imposed the judge is also required to consider or to include in his instructions to the jury "any mitigating circumstances or aggravating circumstances otherwise authorized by law and any of 10. statutory aggravating circumstances which may be supported by the evidence. . . ." 27-2534.1 (b) (Supp. 1975). The scope of the non-statutory aggravating or mitigating circumstances is not delineated in the statute. Before a convicted defendant may be sentenced to death, however, except in cases of treason or aircraft hijacking, the jury, or the trial judge in cases tried without a jury, must find beyond a reasonable doubt one of the 10 aggravating circumstances specified [428 U.S. 153, 165] in the statute. 9 The sentence of death may be imposed only if the jury (or judge) finds one of the statutory aggravating circumstances and then elects to [428 U.S. 153, 166] impose that sentence. 26-3102 (Supp. 1975). If the verdict is death, the jury or judge must specify the aggravating circumstance(s) found. 27-2534.1 (c) (Supp. 1975). In jury cases, the trial judge is bound by the jury's recommended sentence. 26-3102, 27-2514 (Supp. 1975).
In addition to the conventional appellate process available in all criminal cases, provision is made for special expedited direct review by the Supreme Court of Georgia of the appropriateness of imposing the sentence of death in the particular case. The court is directed to consider "the punishment as well as any errors enumerated by way of appeal," and to determine:
A transcript and complete record of the trial, as well as a separate report by the trial judge, are transmitted to the court for its use in reviewing the sentence. 27-2537 (a) (Supp. 1975). The report is in the form of a 6 1/2-page questionnaire, designed to elicit information about the defendant, the crime, and the circumstances of the trial. It requires the trial judge to characterize the trial in several ways designed to test for arbitrariness and disproportionality of sentence. Included in the report are responses to detailed questions concerning the quality of the defendant's representation, whether race played a role in the trial, and, whether, in the trial court's judgment, there was any doubt about [428 U.S. 153, 168] the defendant's guilt or the appropriateness of the sentence. A copy of the report is served upon defense counsel. Under its special review authority, the court may either affirm the death sentence or remand the case for resentencing. In cases in which the death sentence is affirmed there remains the possibility of executive clemency. 11
We address initially the basic contention that the punishment of death for the crime of murder is, under all circumstances, "cruel and unusual" in violation of the Eighth and Fourteenth Amendments of the Constitution. In Part IV of this opinion, we will consider the sentence of death imposed under the Georgia statutes at issue in this case.
The Court on a number of occasions has both assumed and asserted the constitutionality of capital punishment. In several cases that assumption provided a necessary foundation for the decision, as the Court was asked to decide whether a particular method of carrying out a capital sentence would be allowed to stand under the Eighth Amendment. 12 But until Furman v. Georgia, 408 U.S. 238 (1972), the Court never confronted squarely the fundamental claim that the punishment of death always, regardless of the enormity of the offense or the procedure followed in imposing the sentence, is cruel and [428 U.S. 153, 169] unusual punishment in violation of the Constitution. Although this issue was presented and addressed in Furman, it was not resolved by the Court. Four Justices would have held that capital punishment is not unconstitutional per se; 13 two Justices would have reached the opposite conclusion; 14 and three Justices, while agreeing that the statutes then before the Court were invalid as applied, left open the question whether such punishment may ever be imposed. 15 We now hold that the punishment of death does not invariably violate the Constitution.
The history of the prohibition of "cruel and unusual" punishment already has been reviewed at length. 16 The phrase first appeared in the English Bill of Rights of 1689, which was drafted by Parliament at the accession of William and Mary. See Granucci, "Nor Cruel and Unusual Punishments Inflicted:" The Original Meaning, 57 Calif. L. Rev. 839, 852-853 (1969). The English version appears to have been directed against punishments unauthorized by statute and beyond the jurisdiction of the sentencing court, as well as those disproportionate to the offense involved. Id., at 860. The [428 U.S. 153, 170] American draftsmen, who adopted the English phrasing in drafting the Eighth Amendment, were primarily concerned, however, with proscribing "tortures" and other "barbarous" methods of punishment." Id., at 842. 17
In the earliest cases raising Eighth Amendment claims, the Court focused on particular methods of execution to determine whether they were too cruel to pass constitutional muster. The constitutionality of the sentence of death itself was not at issue, and the criterion used to evaluate the mode of execution was its similarity to "torture" and other "barbarous" methods. See Wilkerson v. Utah, 99 U.S. 130, 136 (1879) ("[I]t is safe to affirm that punishments of torture . . . and all others in the same line of unnecessary cruelty, are forbidden by that amendment . . ."); In re Kemmler, 136 U.S. 436, 447 (1890) ("Punishments are cruel when they involve torture or a lingering death . . ."). See also Louisiana ex rel. Francis v. Resweber, 329 U.S. 459, 464 (1947) (second attempt at electrocution found not to violate [428 U.S. 153, 171] Eighth Amendment, since failure of initial execution attempt was "an unforeseeable accident" and "[t]here [was] no purpose to inflict unnecessary pain nor any unnecessary pain involved in the proposed execution").
But the Court has not confined the prohibition embodied in the Eighth Amendment to "barbarous" methods that were generally outlawed in the 18th century. Instead, the Amendment has been interpreted in a flexible and dynamic manner. The Court early recognized that "a principle to be vital must be capable of wider application than the mischief which gave it birth." Weems v. United States, 217 U.S. 349, 373 (1910). Thus the Clause forbidding "cruel and unusual" punishments "is not fastened to the obsolete but may acquire meaning as public opinion becomes enlightened by a humane justice." Id., at 378. See also Furman v. Georgia, 408 U.S., at 429 -430 (POWELL, J., dissenting); Trop v. Dulles, 356 U.S. 86, 100 -101 (1958) (plurality opinion).
In Weems the Court addressed the constitutionality of the Philippine punishment of cadena temporal for the crime of falsifying an official document. That punishment included imprisonment for at least 12 years and one day, in chains, at hard and painful labor; the loss of many basic civil rights; and subjection to lifetime surveillance. Although the Court acknowledged the possibility that "the cruelty of pain" may be present in the challenged punishment, 217 U.S., at 366 , it did not rely on that factor, for it rejected the proposition that the Eighth Amendment reaches only punishments that are "inhuman and barbarous, torture and the like." Id., at 368. Rather, the Court focused on the lack of proportion between the crime and the offense:
The substantive limits imposed by the Eighth Amendment on what can be made criminal and punished were discussed in Robinson v. California, 370 U.S. 660 (1962). The Court found unconstitutional a state statute that made the status of being addicted to a narcotic drug a criminal offense. It held, in effect, that it is "cruel and unusual" to impose any punishment at all for the mere status of addiction. The cruelty in the abstract of the actual sentence imposed was irrelevant: "Even one day in prison would be a cruel and unusual punishment for the `crime' of having a common cold." Id., at 667. Most recently, in Furman v. Georgia, supra, three Justices in separate concurring opinions found the Eighth Amendment applicable to procedures employed to select convicted defendants for the sentence of death.
It is clear from the foregoing precedents that the [428 U.S. 153, 173] Eighth Amendment has not been regarded as a static concept. As Mr. Chief Justice Warren said, in an oftquoted phrase, "[t]he Amendment must draw its meaning from the evolving standards of decency that mark the progress of a maturing society." Trop v. Dulles, supra, at 101. See also Jackson v. Bishop, 404 F.2d 571, 579 (CA8 1968). Cf. Robinson v. California, supra, at 666. Thus, an assessment of contemporary values concerning the infliction of a challenged sanction is relevant to the application of the Eighth Amendment. As we develop below more fully, see infra, at 175-176, this assessment does not call for a subjective judgment. It requires, rather, that we look to objective indicia that reflect the public attitude toward a given sanction.
But our cases also make clear that public perceptions of standards of decency with respect to criminal sanctions are not conclusive. A penalty also must accord with "the dignity of man," which is the "basic concept underlying the Eighth Amendment." Trop v. Dulles, supra, at 100 (plurality opinion). This means, at least, that the punishment not be "excessive." When a form of punishment in the abstract (in this case, whether capital punishment may ever be imposed as a sanction for murder) rather than in the particular (the propriety of death as a penalty to be applied to a specific defendant for a specific crime) is under consideration, the inquiry into "excessiveness" has two aspects. First, the punishment must not involve the unnecessary and wanton infliction of pain. Furman v. Georgia, supra, at 392-393 (BURGER, C. J., dissenting). See Wilkerson v. Utah, 99 U.S., at 136 ; Weems v. United States, supra, at 381. Second, the punishment must not be grossly out of proportion to the severity of the crime. Trop v. Dulles, supra, at 100 (plurality opinion) (dictum); Weems v. United States, supra, at 367. [428 U.S. 153, 174]
Of course, the requirements of the Eighth Amendment must be applied with an awareness of the limited role to be played by the courts. This does not mean that judges have no role to play, for the Eighth Amendment is a restraint upon the exercise of legislative power.
But, while we have an obligation to insure that constitutional [428 U.S. 153, 175] bounds are not overreached, we may not act as judges as we might as legislators.
This is true in part because the constitutional test is intertwined with an assessment of contemporary standards and the legislative judgment weighs heavily in ascertaining such standards. "[I]n a democratic society legislatures, not courts, are constituted to respond to the will and consequently the moral values of the people." [428 U.S. 153, 176] Furman v. Georgia, supra, at 383 (BURGER, C. J., dissenting). The deference we owe to the decisions of the state legislatures under our federal system, 408 U.S., at 465 -470 (REHNQUIST, J., dissenting), is enhanced where the specification of punishments is concerned, for "these are peculiarly questions of legislative policy." Gore v. United States, 357 U.S. 386, 393 (1958). Cf. Robinson v. California, 370 U.S., at 664 -665; Trop v. Dulles, 356 U.S., at 103 (plurality opinion); In re Kemmler, 136 U.S., at 447 . Caution is necessary lest this Court become, "under the aegis of the Cruel and Unusual Punishment Clause, the ultimate arbiter of the standards of criminal responsibility . . . throughout the country." Powell v. Texas, 392 U.S. 514, 533 (1968) (plurality opinion). A decision that a given punishment is impermissible under the Eighth Amendment cannot be reversed short of a constitutional amendment. The ability of the people to express their preference through the normal democratic processes, as well as through ballot referenda, is shut off. Revisions cannot be made in the light of further experience. See Furman v. Georgia, supra, at 461-462 (POWELL, J., dissenting).
In the discussion to this point we have sought to identify the principles and considerations that guide a court in addressing an Eighth Amendment claim. We now consider specifically whether the sentence of death for the crime of murder is a per se violation of the Eighth and Fourteenth Amendments to the Constitution. We note first that history and precedent strongly support a negative answer to this question.
The imposition of the death penalty for the crime of murder has a long history of acceptance both in the United States and in England. The common-law rule [428 U.S. 153, 177] imposed a mandatory death sentence on all convicted murderers. McGautha v. California, 402 U.S. 183, 197 -198 (1971). And the penalty continued to be used into the 20th century by most American States, although the breadth of the common-law rule was diminished, initially by narrowing the class of murders to be punished by death and subsequently by widespread adoption of laws expressly granting juries the discretion to recommend mercy. Id., at 199-200. See Woodson v. North Carolina, post, at 289-292.
It is apparent from the text of the Constitution itself that the existence of capital punishment was accepted by the Framers. At the time the Eighth Amendment was ratified, capital punishment was a common sanction in every State. Indeed, the First Congress of the United States enacted legislation providing death as the penalty for specified crimes. C. 9, 1 Stat. 112 (1790). The Fifth Amendment, adopted at the same time as the Eighth, contemplated the continued existence of the capital sanction by imposing certain limits on the prosecution of capital cases:
For nearly two centuries, this Court, repeatedly and [428 U.S. 153, 178] often expressly, has recognized that capital punishment is not invalid per se. In Wilkerson v. Utah, 99 U.S., at 134 -135, where the Court found no constitutional violation in inflicting death by public shooting, it said:
The petitioners in the capital cases before the Court today renew the "standards of decency" argument, but developments during the four years since Furman have undercut substantially the assumptions upon which their argument rested. Despite the continuing debate, dating back to the 19th century, over the morality and utility of capital punishment, it is now evident that a large proportion of American society continues to regard it as an appropriate and necessary criminal sanction.
The most marked indication of society's endorsement of the death penalty for murder is the legislative response to Furman. The legislatures of at least 35 States 23 have enacted new statutes that provide for the [428 U.S. 153, 180] death penalty for at least some crimes that result in the death of another person. And the Congress of the United States, in 1974, enacted a statute providing the death penalty for aircraft piracy that results in death. 24 These recently adopted statutes have attempted to address the concerns expressed by the Court in Furman primarily (i) by specifying the factors to be weighed and the procedures to be followed in deciding when to impose a capital sentence, or (ii) by making the death penalty mandatory for specified crimes. But all of the post-Furman statutes make clear that capital punishment [428 U.S. 153, 181] itself has not been rejected by the elected representatives of the people.
In the only statewide referendum occurring since Furman and brought to our attention, the people of California adopted a constitutional amendment that authorized capital punishment, in effect negating a prior ruling by the Supreme Court of California in People v. Anderson, 6 Cal. 3d 628, 493 P.2d 880, cert. denied, 406 U.S. 958 (1972), that the death penalty violated the California Constitution. 25
The jury also is a significant and reliable objective index of contemporary values because it is so directly involved. See Furman v. Georgia, 408 U.S., at 439 -440 (POWELL, J., dissenting). See generally Powell, Jury Trial of Crimes, 23 Wash. & Lee L. Rev. 1 (1966). The Court has said that "one of the most important functions any jury can perform in making . . . a selection [between life imprisonment and death for a defendant convicted in a capital case] is to maintain a link between contemporary community values and the penal system." Witherspoon v. Illinois, 391 U.S. 510, 519 n. 15 (1968). It may be true that evolving standards have influenced juries in [428 U.S. 153, 182] recent decades to be more discriminating in imposing the sentence of death. 26 But the relative infrequency of jury verdicts imposing the death sentence does not indicate rejection of capital punishment per se. Rather, the reluctance of juries in many cases to impose the sentence may well reflect the humane feeling that this most irrevocable of sanctions should be reserved for a small number of extreme cases. See Furman v. Georgia, supra, at 388 (BURGER, C. J., dissenting). Indeed, the actions of juries in many States since Furman are fully compatible with the legislative judgments, reflected in the new statutes, as to the continued utility and necessity of capital punishment in appropriate cases. At the close of 1974 at least 254 persons had been sentenced to death since Furman, 27 and by the end of March 1976, more than 460 persons were subject to death sentences.
As we have seen, however, the Eighth Amendment demands more than that a challenged punishment be acceptable to contemporary society. The Court also must ask whether it comports with the basic concept of human dignity at the core of the Amendment. Trop v. Dulles, 356 U.S., at 100 (plurality opinion). Although we cannot "invalidate a category of penalties because we deem less severe penalties adequate to serve the ends of [428 U.S. 153, 183] penology," Furman v. Georgia, supra, at 451 (POWELL, J., dissenting), the sanction imposed cannot be so totally without penological justification that it results in the gratuitous infliction of suffering. Cf. Wilkerson v. Utah, 99 U.S., at 135 -136; In re Kemmler, 136 U.S., at 447 .
The death penalty is said to serve two principal social purposes: retribution and deterrence of capital crimes by prospective offenders. 28
In part, capital punishment is an expression of society's moral outrage at particularly offensive conduct. 29 This function may be unappealing to many, but it is essential in an ordered society that asks its citizens to rely on legal processes rather than self-help to vindicate their wrongs.
The value of capital punishment as a deterrent of crime is a complex factual issue the resolution of which properly rests with the legislatures, which can evaluate the results of statistical studies in terms of their own local conditions and with a flexibility of approach that is not available to the courts. Furman v. Georgia, supra, at 403-405 (BURGER, C. J., dissenting). Indeed, many of the post-Furman statutes reflect just such a responsible effort to define those crimes and those criminals for which capital punishment is most probably an effective deterrent.
In sum, we cannot say that the judgment of the Georgia Legislature that capital punishment may be necessary in some cases is clearly wrong. Considerations of federalism, as well as respect for the ability of a legislature [428 U.S. 153, 187] to evaluate, in terms of its particular State, the moral consensus concerning the death penalty and its social utility as a sanction, require us to conclude, in the absence of more convincing evidence, that the infliction of death as a punishment for murder is not without justification and thus is not unconstitutionally severe.
Finally, we must consider whether the punishment of death is disproportionate in relation to the crime for which it is imposed. There is no question that death as a punishment is unique in its severity and irrevocability. Furman v. Georgia, 408 U.S., at 286 -291 (BRENNAN, J., concurring); id., at 306 (STEWART. J., concurring). When a defendant's life is at stake, the Court has been particularly sensitive to insure that every safeguard is observed. Powell v. Alabama, 287 U.S. 45, 71 (1932); Reid v. Covert, 354 U.S. 1, 77 (1957) (Harlan, J., concurring in result). But we are concerned here only with the imposition of capital punishment for the crime of murder, and when a life has been taken deliberately by the offender, 35 we cannot say that the punishment is invariably disproportionate to the crime. It is an extreme sanction, suitable to the most extreme of crimes.
We hold that the death penalty is not a form of punishment that may never be imposed, regardless of the circumstances of the offense, regardless of the character of the offender, and regardless of the procedure followed in reaching the decision to impose it.
We now consider whether Georgia may impose the death penalty on the petitioner in this case. [428 U.S. 153, 188]
While Furman did not hold that the infliction of the death penalty per se violates the Constitution's ban on cruel and unusual punishments, it did recognize that the penalty of death is different in kind from any other punishment imposed under our system of criminal justice. Because of the uniqueness of the death penalty, Furman held that it could not be imposed under sentencing procedures that created a substantial risk that it would be inflicted in an arbitrary and capricious manner. MR. JUSTICE WHITE concluded that "the death penalty is exacted with great infrequency even for the most atrocious crimes and . . . there is no meaningful basis for distinguishing the few cases in which it is imposed from the many cases in which it is not." 408 U.S., at 313 (concurring). Indeed, the death sentences examined by the Court in Furman were "cruel and unusual in the same way that being struck by lightning is cruel and unusual. For, of all the people convicted of [capital crimes], many just as reprehensible as these, the petitioners [in Furman were] among a capriciously selected random handful upon whom the sentence of death has in fact been imposed. . . . [T]he Eighth and Fourteenth Amendments cannot tolerate the infliction of a sentence of death under legal systems that permit this unique penalty to be so wantonly and so freakishly imposed." Id., at 309-310 (STEWART, J., concurring). 36 [428 U.S. 153, 189]
Furman mandates that where discretion is afforded a sentencing body on a matter so grave as the determination of whether a human life should be taken or spared, that discretion must be suitably directed and limited so as to minimize the risk of wholly arbitrary and capricious action.
It is certainly not a novel proposition that discretion in the area of sentencing be exercised in an informed manner. We have long recognized that "[f]or the determination of sentences, justice generally requires . . . that there be taken into account the circumstances of the offense together with the character and propensities of the offender." Pennsylvania ex rel. Sullivan v. Ashe, 302 U.S. 51, 55 (1937). See also Williams v. Oklahoma, 358 U.S. 576, 585 (1959); Williams v. New York, 337 U.S., at 247 . 37 Otherwise, "the system cannot function in a consistent and a rational manner." American Bar Association Project on Standards for Criminal Justice, Sentencing Alternatives and Procedures 4.1 (a), Commentary, p. 201 (App. Draft 1968). See also President's Commission on Law Enforcement and Administration of Justice, The Challenge of Crime in a Free Society 144 (1967); ALI, Model Penal Code 7.07, Comment 1, pp. 52-53 (Tent. Draft No. 2, 1954). 38 [428 U.S. 153, 190]
The cited studies assumed that the trial judge would be the sentencing authority. If an experienced trial judge, who daily faces the difficult task of imposing sentences, has a vital need for accurate information about a defendant and the crime he committed in order to be able to impose a rational sentence in the typical criminal case, then accurate sentencing information is an indispensable prerequisite to a reasoned determination of whether a defendant shall live or die by a jury of people who may never before have made a sentencing decision.
Jury sentencing has been considered desirable in capital cases in order "to maintain a link between contemporary community values and the penal system - a link without which the determination of punishment could hardly reflect `the evolving standards of decency that mark the progress of a maturing society.'" 39 But it creates special problems. Much of the information that is relevant to the sentencing decision may have no relevance to the question of guilt, or may even be extremely prejudicial to a fair determination of that question. 40 This problem, however, is scarcely insurmountable. Those who have studied the question suggest that a bifurcated procedure - one in which the [428 U.S. 153, 191] question of sentence is not considered until the determination of guilt has been made - is the best answer. The drafters of the Model Penal Code concluded:
But the provision of relevant information under fair procedural rules is not alone sufficient to guarantee that the information will be properly used in the imposition of punishment, especially if sentencing is performed by a jury. Since the members of a jury will have had little, if any, previous experience in sentencing, they are unlikely to be skilled in dealing with the information they are given. See American Bar Association Project on Standards for Criminal Justice, Sentencing Alternatives and Procedures, 1.1 (b), Commentary, pp. 46-47 (Approved Draft 1968); President's Commission on Law Enforcement and Administration of Justice: The Challenge of Crime in a Free Society, Task Force Report: The Courts 26 (1967). To the extent that this problem is inherent in jury sentencing, it may not be totally correctible. It seems clear, however, that the problem will be alleviated if the jury is given guidance regarding the factors about the crime and the defendant that the State, representing organized society, deems particularly relevant to the sentencing decision.
The idea that a jury should be given guidance in its [428 U.S. 153, 193] decisionmaking is also hardly a novel proposition. Juries are invariably given careful instructions on the law and how to apply it before they are authorized to decide the merits of a lawsuit. It would be virtually unthinkable to follow any other course in a legal system that has traditionally operated by following prior precedents and fixed rules of law. 42 See Gasoline Products Co. v. Champlin Refining Co., 283 U.S. 494, 498 (1931); Fed. Rule Civ. Proc. 51. When erroneous instructions are given, retrial is often required. It is quite simply a hallmark of our legal system that juries be carefully and adequately guided in their deliberations.
While some have suggested that standards to guide a capital jury's sentencing deliberation are impossible to formulate, 43 the fact is that such standards have been developed. When the drafters of the Model Penal Code faced this problem, they concluded "that it is within the realm of possibility to point to the main circumstances of aggravation and of mitigation that should be weighed and weighed against each other when they are presented in a concrete case." ALI, Model Penal Code 201.6, Comment 3, p. 71 (Tent. Draft No. 9, 1959) (emphasis in original). 44 While such standards are by [428 U.S. 153, 194] necessity somewhat general, they do provide guidance to the sentencing authority and thereby reduce the likelihood that it will impose a sentence that fairly can be [428 U.S. 153, 195] called capricious or arbitrary. 45 Where the sentencing authority is required to specify the factors it relied upon in reaching its decision, the further safeguard of meaningful appellate review is available to ensure that death sentences are not imposed capriciously or in a freakish manner.
In summary, the concerns expressed in Furman that the penalty of death not be imposed in an arbitrary or capricious manner can be met by a carefully drafted statute that ensures that the sentencing authority is given adequate information and guidance. As a general proposition these concerns are best met by a system that provides for a bifurcated proceeding at which the sentencing authority is apprised of the information relevant to the imposition of sentence and provided with standards to guide its use of the information.
We do not intend to suggest that only the above-described procedures would be permissible under Furman or that any sentencing system constructed along these general lines would inevitably satisfy the concerns of Furman, 46 for each distinct system must be examined on an individual basis. Rather, we have embarked upon this general exposition to make clear that it is possible to construct capital-sentencing systems capable of meeting Furman's constitutional concerns. 47 [428 U.S. 153, 196]
We now turn to consideration of the constitutionality of Georgia's capital-sentencing procedures. In the wake of Furman, Georgia amended its capital punishment statute, but chose not to narrow the scope of its murder provisions. See Part II, supra. Thus, now as before Furman, in Georgia "[a] person commits murder when he unlawfully and with malice aforethought, either express or implied, causes the death of another human being." Ga. Code Ann., 26-1101 (a) (1972). All persons convicted of murder "shall be punished by death or by imprisonment for life." 26-1101 (c) (1972).
Georgia did act, however, to narrow the class of murderers subject to capital punishment by specifying 10 [428 U.S. 153, 197] statutory aggravating circumstances, one of which must be found by the jury to exist beyond a reasonable doubt before a death sentence can ever be imposed. 48 In addition, the jury is authorized to consider any other appropriate aggravating or mitigating circumstances. 27-2534.1 (b) (Supp. 1975). The jury is not required to find any mitigating circumstance in order to make a recommendation of mercy that is binding on the trial court, see 27-2302 (Supp. 1975), but it must find a statutory aggravating circumstance before recommending a sentence of death.
These procedures require the jury to consider the circumstances of the crime and the criminal before it recommends sentence. No longer can a Georgia jury do as Furman's jury did: reach a finding of the defendant's guilt and then, without guidance or direction, decide whether he should live or die. Instead, the jury's attention is directed to the specific circumstances of the crime: Was it committed in the course of another capital felony? Was it committed for money? Was it committed upon a peace officer or judicial officer? Was it committed in a particularly heinous way or in a manner that endangered the lives of many persons? In addition, the jury's attention is focused on the characteristics of the person who committed the crime: Does he have a record of prior convictions for capital offenses? Are there any special facts about this defendant that mitigate against imposing capital punishment (e. g., his youth, the extent of his cooperation with the police, his emotional state at the time of the crime). 49 As a result, while [428 U.S. 153, 198] some jury discretion still exists, "the discretion to be exercised is controlled by clear and objective standards so as to produce non-discriminatory application." Coley v. State, 231 Ga. 829, 834, 204 S. E. 2d 612, 615 (1974).
As an important additional safeguard against arbitrariness and caprice, the Georgia statutory scheme provides for automatic appeal of all death sentences to the State's Supreme Court. That court is required by statute to review each sentence of death and determine whether it was imposed under the influence of passion or prejudice, whether the evidence supports the jury's finding of a statutory aggravating circumstance, and whether the sentence is disproportionate compared to those sentences imposed in similar cases. 27-2537 (c) (Supp. 1975).
In short, Georgia's new sentencing procedures require as a prerequisite to the imposition of the death penalty, specific jury findings as to the circumstances of the crime or the character of the defendant. Moreover, to guard further against a situation comparable to that presented in Furman, the Supreme Court of Georgia compares each death sentence with the sentences imposed on similarly situated defendants to ensure that the sentence of death in a particular case is not disproportionate. On their face these procedures seem to satisfy the concerns of Furman. No longer should there be "no meaningful basis for distinguishing the few cases in which [the death penalty] is imposed from the many cases in which it is not." 408 U.S., at 313 (WHITE, J., concurring).
The petitioner contends, however, that the changes in the Georgia sentencing procedures are only cosmetic, that the arbitrariness and capriciousness condemned by Furman continue to exist in Georgia - both in traditional practices that still remain and in the new sentencing procedures adopted in response to Furman. [428 U.S. 153, 199]
First, the petitioner focuses on the opportunities for discretionary action that are inherent in the processing of any murder case under Georgia law. He notes that the state prosecutor has unfettered authority to select those persons whom he wishes to prosecute for a capital offense and to plea bargain with them. Further, at the trial the jury may choose to convict a defendant of a lesser included offense rather than find him guilty of a crime punishable by death, even if the evidence would support a capital verdict. And finally, a defendant who is convicted and sentenced to die may have his sentence commuted by the Governor of the State and the Georgia Board of Pardons and Paroles.
The existence of these discretionary stages is not determinative of the issues before us. At each of these stages an actor in the criminal justice system makes a decision which may remove a defendant from consideration as a candidate for the death penalty. Furman, in contrast, dealt with the decision to impose the death sentence on a specific individual who had been convicted of a capital offense. Nothing in any of our cases suggests that the decision to afford an individual defendant mercy violates the Constitution. Furman held only that, in order to minimize the risk that the death penalty would be imposed on a capriciously selected group of offenders, the decision to impose it had to be guided by standards so that the sentencing authority would focus on the particularized circumstances of the crime and the defendant. 50 [428 U.S. 153, 200]
The petitioner further contends that the capital-sentencing procedures adopted by Georgia in response to Furman do not eliminate the dangers of arbitrariness and caprice in jury sentencing that were held in Furman to be violative of the Eighth and Fourteenth Amendments. He claims that the statute is so broad and vague as to leave juries free to act as arbitrarily and capriciously as they wish in deciding whether to impose the death penalty. While there is no claim that the jury in this case relied upon a vague or overbroad provision to establish the existence of a statutory aggravating circumstance, the petitioner looks to the sentencing system as a whole (as the Court did in Furman and we do today) and argues that it fails to reduce sufficiently the risk of arbitrary infliction of death sentences. Specifically, Gregg urges that the statutory aggravating circumstances are too broad and too vague, that the sentencing procedure allows for arbitrary grants of mercy, and that the scope of the evidence and argument that can be considered at the presentence hearing is too wide. [428 U.S. 153, 201]
The petitioner attacks the seventh statutory aggravating circumstance, which authorizes imposition of the death penalty if the murder was "outrageously or wantonly vile, horrible or inhuman in that it involved torture, depravity of mind, or an aggravated battery to the victim," contending that it is so broad that capital punishment could be imposed in any murder case. 51 It is, of course, arguable that any murder involves depravity of mind or an aggravated battery. But this language need not be construed in this way, and there is no reason to assume that the Supreme Court of Georgia will adopt such an open-ended construction. 52 In only one case has it upheld a jury's decision to sentence a defendant to death when the only statutory aggravating circumstance found was that of the seventh, see McCorquodale v. State, 233 Ga. 369, 211 S. E. 2d 577 (1974), and that homicide was a horrifying torture-murder. 53 [428 U.S. 153, 202]
The petitioner also argues that two of the statutory aggravating circumstances are vague and therefore susceptible of widely differing interpretations, thus creating a substantial risk that the death penalty will be arbitrarily inflicted by Georgia juries. 54 In light of the decisions of the Supreme Court of Georgia we must disagree. First, the petitioner attacks that part of 27-2534.1 (b) (1) that authorizes a jury to consider whether a defendant has a "substantial history of serious assaultive criminal convictions." The Supreme Court of Georgia, however, has demonstrated a concern that the new sentencing procedures provide guidance to juries. It held this provision to be impermissibly vague in Arnold v. State, 236 Ga. 534, 540, 224 S. E. 2d 386, 391 (1976), because it did not provide the jury with "sufficiently `clear and objective standards.'" Second, the petitioner points to 27-2534.1 (b) (3) which speaks of creating a "great risk of death to more than one person." While such a phrase might be susceptible of an overly broad interpretation, the Supreme Court of Georgia has not so construed it. The only case in which the court upheld a conviction in reliance on this aggravating circumstance involved a man who stood up in a church and fired a gun indiscriminately into the audience. See [428 U.S. 153, 203] Chenault v. State, 234 Ga. 216, 215 S. E. 2d 223 (1975). On the other hand, the court expressly reversed a finding of great risk when the victim was simply kidnaped in a parking lot. See Jarrell v. State, 234 Ga. 410, 424, 216 S. E. 2d 258, 269 (1975). 55
The petitioner next argues that the requirements of Furman are not met here because the jury has the power to decline to impose the death penalty even if it finds that one or more statutory aggravating circumstances are present in the case. This contention misinterprets Furman. See supra, at 198-199. Moreover, it ignores the role of the Supreme Court of Georgia which reviews each death sentence to determine whether it is proportional to other sentences imposed for similar crimes. Since the proportionality requirement on review is intended to prevent caprice in the decision to inflict the penalty, the isolated decision of a jury to afford mercy does not render unconstitutional death sentences imposed on defendants who were sentenced under a system that does not create a substantial risk of arbitrariness or caprice.
The petitioner objects, finally, to the wide scope of evidence and argument allowed at presentence hearings. We think that the Georgia court wisely has chosen not to impose unnecessary restrictions on the evidence that can be offered at such a hearing and to approve open and far-ranging argument. See, e. g., Brown v. State, 235 Ga. 644, 220 S. E. 2d 922 (1975). So long as the [428 U.S. 153, 204] evidence introduced and the arguments made at the presentence hearing do not prejudice a defendant, it is preferable not to impose restrictions. We think it desirable for the jury to have as much information before it as possible when it makes the sentencing decision. See supra, at 189-190.
Finally, the Georgia statute has an additional provision designed to assure that the death penalty will not be imposed on a capriciously selected group of convicted defendants. The new sentencing procedures require that the State Supreme Court review every death sentence to determine whether it was imposed under the influence of passion, prejudice, or any other arbitrary factor, whether the evidence supports the findings of a statutory aggravating circumstance, and "[w]hether the sentence of death is excessive or disproportionate to the penalty imposed in similar cases, considering both the crime and the defendant." 27-2537 (c) (3) (Supp. 1975). 56 In performing [428 U.S. 153, 205] its sentence-review function, the Georgia court has held that "if the death penalty is only rarely imposed for an act or it is substantially out of line with sentences imposed for other acts it will be set aside as excessive." Coley v. State, 231 Ga., at 834, 204 S. E. 2d, at 616. The court on another occasion stated that "we view it to be our duty under the similarity standard to assure that no death sentence is affirmed unless in similar cases throughout the state the death penalty has been imposed generally . . . ." Moore v. State, 233 Ga. 861, 864, 213 S. E. 2d 829, 832 (1975). See also Jarrell v. State, supra, at 425, 216 S. E. 2d, at 270 (standard is whether "juries generally throughout the state have imposed the death penalty"); Smith v. State, 236 Ga. 12, 24, 222 S. E. 2d 308, 318 (1976) (found "a clear pattern" of jury behavior).
It is apparent that the Supreme Court of Georgia has taken its review responsibilities seriously. In Coley, it held that "[t]he prior cases indicate that the past practice among juries faced with similar factual situations and like aggravating circumstances has been to impose only the sentence of life imprisonment for the offense of rape, rather than death." 231 Ga., at 835, 204 S. E. 2d, at 617. It thereupon reduced Coley's sentence from death to life imprisonment. Similarly, although armed robbery is a capital offense under Georgia law, 26-1902 (1972), the Georgia court concluded that the death sentences imposed in this case for that crime were "unusual in that they are rarely imposed for [armed robbery]. Thus, under the test provided by statute, . . . they must be considered to be excessive or disproportionate to the penalties imposed in similar cases." 233 [428 U.S. 153, 206] Ga., at 127, 210 S. E. 2d, at 667. The court therefore vacated Gregg's death sentences for armed robbery and has followed a similar course in every other armed robbery death penalty case to come before it. See Floyd v. State, 233 Ga. 280, 285, 210 S. E. 2d 810, 814 (1974); Jarrell v. State, 234 Ga., at 424-425, 216 S. E. 2d, at 270. See Dorsey v. State, 236 Ga. 591, 225 S. E. 2d 418 (1976).
The provision for appellate review in the Georgia capital-sentencing system serves as a check against the random or arbitrary imposition of the death penalty. In particular, the proportionality review substantially eliminates the possibility that a person will be sentenced to die by the action of an aberrant jury. If a time comes when juries generally do not impose the death sentence in a certain kind of murder case, the appellate review procedures assure that no defendant convicted under such circumstances will suffer a sentence of death.
The basic concern of Furman centered on those defendants who were being condemned to death capriciously and arbitrarily. Under the procedures before the Court in that case, sentencing authorities were not directed to give attention to the nature or circumstances of the crime committed or to the character or record of the defendant. Left unguided, juries imposed the death sentence in a way that could only be called freakish. The new Georgia sentencing procedures, by contrast, focus the jury's attention on the particularized nature of the crime and the particularized characteristics of the individual defendant. While the jury is permitted to consider any aggravating or mitigating circumstances, it must find and identify at least one statutory aggravating factor before it may impose a penalty of death. In this way the jury's discretion is channeled. No longer [428 U.S. 153, 207] can a jury wantonly and freakishly impose the death sentence; it is always circumscribed by the legislative guidelines. In addition, the review function of the Supreme Court of Georgia affords additional assurance that the concerns that prompted our decision in Furman are not present to any significant degree in the Georgia procedure applied here.
For the reasons expressed in this opinion, we hold that the statutory system under which Gregg was sentenced to death does not violate the Constitution. Accordingly, the judgment of the Georgia Supreme Court is affirmed.
[ Footnote 2 ] The court further held, in part, that the trial court did not err in refusing to instruct the jury with respect to voluntary manslaughter since there was no evidence to support that verdict.
[ Footnote 3 ] Subsequent to the trial in this case limited portions of the Georgia statute were amended. None of these amendments changed significantly the substance of the statutory scheme. All references to the statute in this opinion are to the current version.
[ Footnote 4 ] Georgia Code Ann. 26-1101 (1972) provides:
[ Footnote 5 ] Section 26-1902 (1972) provides:
[ Footnote 6 ] These capital felonies currently are defined as they were when Furman was decided. The 1973 amendments to the Georgia statute, however, narrowed the class of crimes potentially punishable by death by eliminating capital perjury. Compare 26-2401 (Supp. 1975) with 26-2401 (1972).
[ Footnote 7 ] It is not clear whether the 1974 amendments to the Georgia statute were intended to broaden the types of evidence admissible at the presentence hearing. Compare 27-2503 (a) (Supp. 1975) with 27-2534 (1972) (deletion of limitation "subject to the laws of evidence").
[ Footnote 8 ] Essentially the same procedures are followed in the case of a guilty plea. The judge considers the factual basis of the plea, as well as evidence in aggravation and mitigation. See Mitchell v. State, 234 Ga. 160, 214 S. E. 2d 900 (1975).
[ Footnote 9 ] The statute provides in part:
[ Footnote 10 ] The statute requires that the Supreme Court of Georgia obtain and preserve the records of all capital felony cases in which the death penalty was imposed after January 1, 1970, or such earlier date that the court considers appropriate. 27-2537 (f) (Supp. 1975). To aid the court in its disposition of these cases the statute further provides for the appointment of a special assistant and authorizes the employment of additional staff members. 27-2537 (f)-(h) (Supp. 1975).

Since five Justices wrote separately in support of the judgments in Furman, the holding of the Court may be viewed as that position taken by those Members who concurred in the judgments on the narrowest grounds - MR. JUSTICE STEWART and MR. JUSTICE WHITE. See n. 36, infra.
[ Footnote 16 ] 408 U.S., at 316 -328 (MARSHALL, J., concurring).
[ Footnote 17 ] This conclusion derives primarily from statements made during the debates in the various state conventions called to ratify the Federal Constitution. For example, Virginia delegate Patrick Henry objected vehemently to the lack of a provision banning "cruel and unusual punishments":
[ Footnote 18 ] The Court remarked on the fact that the law under review "has come to us from a government of a different form and genius from ours," but it also noted that the punishments it inflicted "would have those bad attributes even if they were found in a Federal enactment and not taken from an alien source." 217 U.S., at 377 .
[ Footnote 19 ] Although legislative measures adopted by the people's chosen representatives provide one important means of ascertaining contemporary values, it is evident that legislative judgments alone cannot be determinative of Eighth Amendment standards since that Amendment was intended to safeguard individuals from the abuse of legislative power. See Weems v. United States, 217 U.S. 349, 371 -373 (1910); Furman v. Georgia, 408 U.S., at 258 -269 (BRENNAN, J., concurring). Robinson v. California, 370 U.S. 660 (1962), illustrates the proposition that penal laws enacted by state legislatures may violate the Eighth Amendment because "in the light of contemporary human knowledge" they "would doubtless be universally thought to be an infliction of cruel and unusual punishment." Id., at 666. At the time of Robinson nine States in addition to California had criminal laws that punished addiction similar to the law declared unconstitutional in Robinson.

[ Footnote 26 ] The number of prisoners who received death sentences in the years from 1961 to 1972 varied from a high of 140 in 1961 to a low of 75 in 1972, with wide fluctuations in the intervening years: 103 in 1962; 93 in 1963; 106 in 1964; 86 in 1965; 118 in 1966; 85 in 1967; 102 in 1968; 97 in 1969; 127 in 1970; and 104 in 1971. Department of Justice, National Prisoner Statistics Bulletin, Capital Punishment 1971-1972, p. 20 (Dec. 1974).

[ Footnote 33 ] Other types of calculated murders, apparently occurring with increasing frequency, include the use of bombs or other means of indiscriminate killings, the extortion murder of hostages or kidnap victims, and the execution-style killing of witnesses to a crime.
[ Footnote 34 ] We have been shown no statistics breaking down the total number of murders into the categories described above. The overall trend in the number of murders committed in the nation, however, has been upward for some time. In 1964, reported murders totaled an estimated 9,250. During the ensuing decade, the number reported increased 123%, until it totaled approximately 20,600 in 1974. In 1972, the year Furman was announced, the total estimated was 18,520. Despite a fractional decrease in 1975 as compared with 1974, the number of murders increased in the three years immediately following Furman to approximately 20,400, an increase of almost 10%. See FBI, Uniform Crime Reports, for 1964, 1972, 1974, and 1975, Preliminary Annual Release.
[ Footnote 35 ] We do not address here the question whether the taking of the criminal's life is a proportionate sanction where no victim has been deprived of life - for example, when capital punishment is imposed for rape, kidnaping, or armed robbery that does not result in the death of any human being.
[ Footnote 36 ] This view was expressed by other Members of the Court who concurred in the judgments. See 408 U.S., at 255 -257 (Douglas, J.); id., at 291-295 (BRENNAN, J.). The dissenters viewed this concern as the basis for the Furman decision: "The decisive grievance of the opinions . . . is that the present system of discretionary sentencing in capital cases has failed to produce even-handed justice; . . . that the selection process has followed no rational pattern." Id., at 398-399 (BURGER, C. J., dissenting).
[ Footnote 37 ] The Federal Rules of Criminal Procedure require as a matter of course that a presentence report containing information about a defendant's background be prepared for use by the sentencing judge. Rule 32 (c). The importance of obtaining accurate sentencing information is underscored by the Rule's direction to the sentencing court to "afford the defendant or his counsel an opportunity to comment [on the report] and, at the discretion of the court, to introduce testimony or other information relating to any alleged factual inaccuracy contained in the presentence report." Rule 32 (c) (3) (A).
[ Footnote 38 ] Indeed, we hold elsewhere today that in capital cases it is constitutionally required that the sentencing authority have information [428 U.S. 153, 190] sufficient to enable it to consider the character and individual circumstances of a defendant prior to imposition of a death sentence. See Woodson v. North Carolina, post, at 303-305.
[ Footnote 39 ] Witherspoon v. Illinois, 391 U.S., at 519 n. 15, quoting Trop v. Dulles, 356 U.S., at 101 (plurality opinion). See also Report of the Royal Commission on Capital Punishment, 1949-1953, Cmd. 8932, § 571.
[ Footnote 40 ] In other situations this Court has concluded that a jury cannot be expected to consider certain evidence before it on one issue, but not another. See, e. g., Bruton v. United States, 391 U.S. 123 (1968); Jackson v. Denno, 378 U.S. 368 (1964).
[ Footnote 41 ] In United States v. Jackson, 390 U.S. 570 (1968), the Court considered a statute that provided that if a defendant pleaded guilty, the maximum penalty would be life imprisonment, but if a defendant chose to go to trial, the maximum penalty upon conviction was death. In holding that the statute was constitutionally invalid, the Court noted:
[ Footnote 42 ] But see Md. Const., Art. XV, 5: "In the trial of all criminal cases, the jury shall be the Judges of the Law, as well as of fact . . . ." See also Md. Code Ann., art. 27, 593 (1971). Maryland judges, however, typically give advisory instructions on the law to the jury. See Md. Rule 756; Wilson v. State, 239 Md. 245, 210 A. 2d 824 (1965).
[ Footnote 43 ] See McGautha v. California, 402 U.S., at 204 -207; Report of the Royal Commission on Capital Punishment, 1949-1953, Cmd. 8932, § 595.
[ Footnote 44 ] The Model Penal Code proposes the following standards:
[ Footnote 45 ] As MR. JUSTICE BRENNAN noted in McGautha v. California, supra, at 285-286 (dissenting opinion):
[ Footnote 46 ] A system could have standards so vague that they would fail adequately to channel the sentencing decision patterns of juries with the result that a pattern of arbitrary and capricious sentencing like that found unconstitutional in Furman could occur.
[ Footnote 47 ] In McGautha v. California, supra, this Court held that the [428 U.S. 153, 196] Due Process Clause of the Fourteenth Amendment did not require that a jury be provided with standards to guide its decision whether to recommend a sentence of life imprisonment or death or that the capital-sentencing proceeding be separated from the guilt-determination process. McGautha was not an Eighth Amendment decision, and to the extent it purported to deal with Eighth Amendment concerns, it must be read in light of the opinions in Furman v. Georgia. There the Court ruled that death sentences imposed under statutes that left juries with untrammeled discretion to impose or withhold the death penalty violated the Eighth and Fourteenth Amendments. While Furman did not overrule McGautha, it is clearly in substantial tension with a broad reading of McGautha's holding. In view of Furman, McGautha can be viewed rationally as a precedent only for the proposition that standardless jury sentencing procedures were not employed in the cases there before the Court so as to violate the Due Process Clause. We note that McGautha's assumption that it is not possible to devise standards to guide and regularize jury sentencing in capital cases has been undermined by subsequent experience. In view of that experience and the considerations set forth in the text, we adhere to Furman's determination that where the ultimate punishment of death is at issue a system of standardless jury discretion violates the Eighth and Fourteenth Amendments.
[ Footnote 48 ] The text of the statute enumerating the various aggravating circumstances is set out at n. 9, supra.
[ Footnote 49 ] See Moore v. State, 233 Ga. 861, 865, 213 S. E. 2d 829, 832 (1975).
[ Footnote 50 ] The petitioner's argument is nothing more than a veiled contention that Furman indirectly outlawed capital punishment by placing totally unrealistic conditions on its use. In order to repair the alleged defects pointed to by the petitioner, it would be necessary to require that prosecuting authorities charge a capital offense whenever arguably there had been a capital murder and that they [428 U.S. 153, 200] refuse to plea bargain with the defendant. If a jury refused to convict even though the evidence supported the charge, its verdict would have to be reversed and a verdict of guilty entered or a new trial ordered, since the discretionary act of jury nullification would not be permitted. Finally, acts of executive clemency would have to be prohibited. Such a system, of course, would be totally alien to our notions of criminal justice.
Moreover, it would be unconstitutional. Such a system in many respects would have the vices of the mandatory death penalty statutes we hold unconstitutional today in Woodson v. North Carolina, post, p. 280, and Roberts v. Louisiana, post, p. 325. The suggestion that a jury's verdict of acquittal could be overturned and a defendant retried would run afoul of the Sixth Amendment jury-trial guarantee and the Double Jeopardy Clause of the Fifth Amendment. In the federal system it also would be unconstitutional to prohibit a President from deciding, as an act of executive clemency, to reprieve one sentenced to death. U.S. Const., Art. II, 2.
[ Footnote 51 ] In light of the limited grant of certiorari, see supra, at 162, we review the "vagueness" and "overbreadth" of the statutory aggravating circumstances only to consider whether their imprecision renders this capital-sentencing system invalid under the Eighth and Fourteenth Amendments because it is incapable of imposing capital punishment other than by arbitrariness or caprice.
[ Footnote 52 ] In the course of interpreting Florida's new capital-sentencing statute, the Supreme Court of Florida has ruled that the phrase "especially heinous, atrocious or cruel" means a "conscienceless or pitiless crime which is unnecessarily torturous to the victim." State v. Dixon, 283 So.2d 1, 9 (1973). See Proffitt v. Florida, post, at 255-256.
[ Footnote 53 ] Two other reported cases indicate that juries have found aggravating circumstances based on 27-2534.1 (b) (7). In both cases a separate statutory aggravating circumstance was also found, and the Supreme Court of Georgia did not explicitly rely on the finding of the seventh circumstance when it upheld the death sentence. See Jarrell v. State, 234 Ga. 410, 216 S. E. 2d 258 (1975) (State Supreme Court upheld finding that defendant committed two other capital felonies - kidnapping and armed robbery - in the course of [428 U.S. 153, 202] the murder, 27-2534.1 (b) (2); jury also found that the murder was committed for money, 27-2534.1 (b) (4), and that a great risk of death to bystanders was created, 27-2534.1 (b) (3)); Floyd v. State, 233 Ga. 280, 210 S. E. 2d 810 (1974) (found to have committed a capital felony - armed robbery - in the course of the murder, 27-2534.1 (b) (2)).
[ Footnote 54 ] The petitioner also attacks 25-2534.1 (b) (7) as vague. As we have noted in answering his overbreadth argument concerning this section, however, the state court has not given a broad reading to the scope of this provision, and there is no reason to think that juries will not be able to understand it. See n. 51, supra; Proffitt v. Florida, post, at 255-256.
[ Footnote 55 ] The petitioner also objects to the last part of 27-2534.1 (b) (3) which requires that the great risk be created "by means of a weapon or device which would normally be hazardous to the lives of more than one person." While the state court has not focused on this section, it seems reasonable to assume that if a great risk in fact is created, it will be likely that a weapon or device normally hazardous to more than one person will have created it.
[ Footnote 56 ] The court is required to specify in its opinion the similar cases which it took into consideration. 27-2537 (e) (Supp. 1975). Special provision is made for staff to enable the court to compile data relevant to its consideration of the sentence's validity. 27-2537 (f)-(h) (Supp. 1975). See generally supra, at 166-168.
The petitioner claims that this procedure has resulted in an inadequate basis for measuring the proportionality of sentences. First, he notes that nonappealed capital convictions where a life sentence is imposed and cases involving homicides where a capital conviction is not obtained are not included in the group of cases which the Supreme Court of Georgia uses for comparative purposes. The Georgia court has the authority to consider such cases, see Ross v. State, 233 Ga. 361, 365-366, 211 S. E. 2d 356, 359 (1974), and it does consider appealed murder cases where a life sentence has been imposed. We do not think that the petitioner's argument establishes that the Georgia court's review process is ineffective. The petitioner further complains about the Georgia court's current practice of using some pre-Furman cases in its comparative examination. This [428 U.S. 153, 205] practice was necessary at the inception of the new procedure in the absence of any post-Furman capital cases available for comparison. It is not unconstitutional.
MR. JUSTICE WHITE, with whom THE CHIEF JUSTICE and MR. JUSTICE REHNQUIST join, concurring in the judgment.
In Furman v. Georgia, 408 U.S. 238 (1972), this Court held the death penalty as then administered in Georgia to be unconstitutional. That same year the Georgia Legislature enacted a new statutory scheme under which the death penalty may be imposed for several offenses, including murder. The issue in this case is whether the death penalty imposed for murder on petitioner Gregg under the new Georgia statutory scheme may constitutionally be carried out. I agree that it may.
Under the new Georgia statutory scheme a person convicted of murder may receive a sentence either of death or of life imprisonment. Ga. Code Ann. 26-1101 (1972). 1 Under Georgia Code Ann. 26-3102 (Supp. [428 U.S. 153, 208] 1975), the sentence will be life imprisonment unless the jury at a separate evidentiary proceeding immediately following the verdict finds unanimously and beyond a reasonable doubt at least one statutorily defined "aggravating circumstance." 2 The aggravating circumstances are:
An important aspect of the new Georgia legislative scheme, however, is its provision for appellate review. Prompt review by the Georgia Supreme Court is provided for in every case in which the death penalty is imposed. To assist it in deciding whether to sustain the death penalty, the Georgia Supreme Court is supplied, in every case, with a report from the trial judge in the form of a standard questionnaire. 27-2537 (a) (Supp. 1975). The questionnaire contains, inter alia, six questions designed to disclose whether race played a role in the case and one question asking the trial judge whether the evidence forecloses "all doubt respecting the defendant's [428 U.S. 153, 212] guilt." In deciding whether the death penalty is to be sustained in any given case, the court shall determine:
Petitioner Troy Gregg and a 16-year-old companion, Floyd Allen, were hitchhiking from Florida to Asheville, N.C., on November 21, 1973. They were picked up in an automobile driven by Fred Simmons and Bob Moore, both of whom were drunk. The car broke down and Simmons purchased a new one - a 1960 Pontiac - using [428 U.S. 153, 213] part of a large roll of cash which he had with him. After picking up another hitchhiker in Florida and dropping him off in Atlanta, the car proceeded north to Gwinnett County, Ga., where it stopped so that Moore and Simmons could urinate. While they were out of the car Simmons was shot in the eye and Moore was shot in the right cheek and in the back of the head. Both died as a result.
On November 24, 1973, at 3 p. m., on the basis of information supplied by the hitchhiker, petitioner and Allen were arrested in Asheville, N.C. They were then in possession of the car which Simmons had purchased; petitioner was in possession of the gun which had killed Simmons and Moore and $107 which had been taken from them; and in the motel room in which petitioner was staying was a new stereo and a car stereo player.
At about 11 p. m., after the Gwinnett County police had arrived, petitioner made a statement to them admitting that he had killed Moore and Simmons, but asserting that he had killed them in self-defense and in defense of Allen. He also admitted robbing them of $400 and taking their car. A few moments later petitioner was asked why he had shot Moore and Simmons and responded: "By God, I wanted them dead."
At about 1 o'clock the next morning, petitioner and Allen were released to the custody of the Gwinnett County police and were transported in two cars back to Gwinnett County. On the way, at about 5 a. m., the car stopped at the place where Moore and Simmons had been killed. Everyone got out of the car. Allen was asked, in petitioner's presence, how the killing occurred. He said that he had been sitting in the back seat of the 1960 Pontiac and was about half asleep. He woke up when the car stopped. Simmons and Moore got out, and as soon as they did petitioner turned around and told Allen: "Get out, we're going to rob them." Allen said that he [428 U.S. 153, 214] got out and walked toward the back of the car, looked around and could see petitioner, with a gun in his hand, leaning up against the car so he could get a good aim. Simmons and Moore had gone down the bank and had relieved themselves and as they were coming up the bank petitioner fired three shots. One of the men fell, the other staggered. Petitioner then circled around the back and approached the two men, both of whom were now lying in the ditch, from behind. He placed the gun to the head of one of them and pulled the trigger. Then he went quickly to the other one and placed the gun to his head and pulled the trigger again. He then took the money, whatever was in their pockets. He told Allen to get in the car and they drove away.
When Allen had finished telling this story, one of the officers asked petitioner if this was the way it had happened. Petitioner hung his head and said that it was. The officer then said: "You mean you shot these men down in cold blooded murder just to rob them," and petitioner said yes. The officer then asked him why and petitioner said he did not know. Petitioner was indicted in two counts for murder and in two counts for robbery.
At trial, petitioner's defense was that he had killed in self-defense. He testified in his own behalf and told a version of the events similar to that which he had originally told to the Gwinnett County police. On cross-examination, he was confronted with a letter to Allen recounting a version of the events similar to that to which he had just testified and instructing Allen to memorize and burn the letter. Petitioner conceded writing the version of the events, but denied writing the portion of the letter which instructed Allen to memorize and burn it. In rebuttal, the State called a handwriting expert who testified that the entire letter was written by the same person. [428 U.S. 153, 215]
The jury was instructed on the elements of murder 4 and robbery. The trial judge gave an instruction on self-defense, but refused to submit the lesser included [428 U.S. 153, 216] offense of manslaughter to the jury. It returned verdicts of guilty on all counts.
No new evidence was presented at the sentencing proceeding. However, the prosecutor and the attorney for petitioner each made arguments to the jury on the issue of punishment. The prosecutor emphasized the strength of the case against petitioner and the fact that he had murdered in order to eliminate the witnesses to the robbery. The defense attorney emphasized the possibility that a mistake had been made and that petitioner was not guilty. The trial judge instructed the jury on [428 U.S. 153, 217] their sentencing function and in so doing submitted to them three statutory aggravating circumstances. He stated:
On appeal the Georgia Supreme Court affirmed the death sentences on the murder counts and vacated the death sentences on the robbery counts. 233 Ga. 117, 210 S. E. 2d 659 (1974). It concluded that the murder sentences were not imposed under the influence of passion, prejudice, or any other arbitrary factor; that the evidence supported the finding of a statutory aggravating factor with respect to the murders; and, citing several cases in which the death penalty had been imposed previously for murders of persons who had witnessed a robbery, held:
The threshold question in this case is whether the death penalty may be carried out for murder under the Georgia legislative scheme consistent with the decision in Furman v. Georgia, supra. In Furman, this Court held that as a result of giving the sentencer unguided discretion to impose or not to impose the death penalty for murder, the penalty was being imposed discriminatorily, 6 [428 U.S. 153, 221] wantonly and freakishly, 7 and so infrequently 8 that any given death sentence was cruel and unusual. Petitioner argues that, as in Furman, the jury is still the sentencer; that the statutory criteria to be considered by the jury on the issue of sentence under Georgia's new statutory scheme are vague and do not purport to be all-inclusive; and that, in any event, there are no circumstances under which the jury is required to impose the death penalty. 9 Consequently, the petitioner argues that the death penalty will inexorably be imposed in as discriminatory, standardless, and rare a manner as it was imposed under the scheme declared invalid in Furman.
The argument is considerably overstated. The Georgia Legislature has made an effort to identify those aggravating factors which it considers necessary and relevant to the question whether a defendant convicted of capital murder should be sentenced to death. 10 The [428 U.S. 153, 222] jury which imposes sentence is instructed on all statutory aggravating factors which are supported by the evidence, and is told that it may not impose the death penalty unless it unanimously finds at least one of those factors to have been established beyond a reasonable doubt. The Georgia Legislature has plainly made an effort to guide the jury in the exercise of its discretion, while at the same time permitting the jury to dispense mercy on the basis of factors too intangible to write into a statute, and I cannot accept the naked assertion that the effort is bound to fail. As the types of murders for which the death penalty may be imposed become more narrowly defined and are limited to those which are particularly serious or for which the death penalty is peculiarly appropriate as they are in Georgia by reason of the aggravating-circumstance requirement, it becomes reasonable to expect that juries - even given discretion not to impose the death penalty - will impose the death penalty in a substantial portion of the cases so defined. If they do, it can no longer be said that the penalty is being imposed wantonly and freakishly or so infrequently that it loses its usefulness as a sentencing device. There is, therefore, reason to expect that Georgia's current system would escape the infirmities which invalidated its previous system under Furman. However, the Georgia Legislature was not satisfied with a system which might, but also might not, turn out in practice to result in death sentences being imposed with reasonable consistency for certain serious murders. Instead, it gave the Georgia Supreme Court the power and the obligation to perform precisely the task which three Justices of this Court, whose opinions were necessary to the result, performed [428 U.S. 153, 223] in Furman: namely, the task of deciding whether in fact the death penalty was being administered for any given class of crime in a discriminatory, standardless, or rare fashion.
In considering any given death sentence on appeal, the Georgia Supreme Court is to determine whether the sentence imposed was consistent with the relevant statutes - i. e., whether there was sufficient evidence to support the finding of an aggravating circumstance. Ga. Code Ann. 27-2537 (c) (2) (Supp. 1975). However, it must do much more than determine whether the penalty was lawfully imposed. It must go on to decide - after reviewing the penalties imposed in "similar cases" - whether the penalty is "excessive or disproportionate" considering both the crime and the defendant. 27-2537 (c) (3) (Supp. 1975). The new Assistant to the Supreme Court is to assist the court in collecting the records of "all capital felony cases" 11 in the State of Georgia in which sentence was imposed after January 1, 1970. 27-2537 (f) (Supp. 1975). The court also has the obligation of determining whether the penalty was "imposed under the influence of passion, prejudice, or any other arbitrary factor." 27-2537 (c) (1) (Supp. 1975). The Georgia Supreme Court has interpreted the appellate review statute to require it to set aside the death sentence whenever juries across the State impose it only rarely for the type of crime in question; but to require it to affirm death sentences whenever juries across the State generally impose it for the crime in question. [428 U.S. 153, 224] Thus, in this case the Georgia Supreme Court concluded that the death penalty was so rarely imposed for the crime of robbery that it set aside the sentences on the robbery counts, and effectively foreclosed that penalty from being imposed for that crime in the future under the legislative scheme now in existence. Similarly, the Georgia Supreme Court has determined that juries impose the death sentence too rarely with respect to certain classes of rape. Compare Coley v. State, 231 Ga. 829, 204 S. E. 2d 612 (1974), with Coker v. State, 234 Ga. 555, 216 S. E. 2d 782 (1975). However, it concluded that juries "generally throughout the state" have imposed the death penalty for those who murder witnesses to armed robberies. Jarrell v. State, 234 Ga. 410, 425, 216 S. E. 2d 258, 270 (1975). Consequently, it affirmed the sentences in this case on the murder counts. If the Georgia Supreme Court is correct with respect to this factual judgment, imposition of the death penalty in this and similar cases is consistent with Furman. Indeed, if the Georgia Supreme Court properly performs the task assigned to it under the Georgia statutes, death sentences imposed for discriminatory reasons or wantonly or freakishly for any given category of crime will be set aside. Petitioner has wholly failed to establish, and has not even attempted to establish, that the Georgia Supreme Court failed properly to perform its task in this case or that it is incapable of performing its task adequately in all cases; and this Court should not assume that it did not do so.
Petitioner also argues that decisions made by the prosecutor - either in negotiating a plea to some lesser offense than capital murder or in simply declining to charge capital murder - are standardless and will inexorably result in the wanton and freakish imposition of the penalty condemned by the judgment in Furman. I address this [428 U.S. 153, 225] point separately because the cases in which no capital offense is charged escape the view of the Georgia Supreme Court and are not considered by it in determining whether a particular sentence is excessive or disproportionate.
Petitioner's argument that prosecutors behave in a standardless fashion in deciding which cases to try as capital felonies is unsupported by any facts. Petitioner simply asserts that since prosecutors have the power not to charge capital felonies they will exercise that power in a standardless fashion. This is untenable. Absent facts to the contrary, it cannot be assumed that prosecutors will be motivated in their charging decision by factors other than the strength of their case and the likelihood that a jury would impose the death penalty if it convicts. Unless prosecutors are incompetent in their judgments, the standards by which they decide whether to charge a capital felony will be the same as those by which the jury will decide the questions of guilt and sentence. Thus defendants will escape the death penalty through prosecutorial charging decisions only because the offense is not sufficiently serious; or because the proof is insufficiently strong. This does not cause the system to be standardless any more than the jury's decision to impose life imprisonment on a defendant whose crime is deemed insufficiently serious or its decision to acquit someone who is probably guilty but whose guilt is not established beyond a reasonable doubt. Thus the prosecutor's charging decisions are unlikely to have removed from the sample of cases considered by the Georgia Supreme Court any which are truly "similar." If the cases really were "similar" in relevant respects, it is unlikely that prosecutors would fail to prosecute them as capital cases; and I am unwilling to assume the contrary.
Petitioner's argument that there is an unconstitutional [428 U.S. 153, 226] amount of discretion in the system which separates those suspects who receive the death penalty from those who receive life imprisonment, a lesser penalty, or are acquitted or never charged, seems to be in final analysis an indictment of our entire system of justice. Petitioner has argued, in effect, that no matter how effective the death penalty may be as a punishment, government, created and run as it must be by humans, is inevitably incompetent to administer it. This cannot be accepted as a proposition of constitutional law. Imposition of the death penalty is surely an awesome responsibility for any system of justice and those who participate in it. Mistakes will be made and discriminations will occur which will be difficult to explain. However, one of society's most basic tasks is that of protecting the lives of its citizens and one of the most basic ways in which it achieves the task is through criminal laws against murder. I decline to interfere with the manner in which Georgia has chosen to enforce such laws on what is simply an assertion of lack of faith in the ability of the system of justice to operate in a fundamentally fair manner.
For the reasons stated in dissent in Roberts v. Louisiana, post, at 350-356, neither can I agree with the petitioner's other basic argument that the death penalty, however imposed and for whatever crime, is cruel and unusual punishment.
I therefore concur in the judgment of affirmance.
Statement of THE CHIEF JUSTICE and MR. JUSTICE REHNQUIST:
We concur in the judgment and join the opinion of MR. JUSTICE WHITE, agreeing with its analysis that Georgia's system of capital punishment comports with [428 U.S. 153, 227] the Court's holding in Furman v. Georgia, 408 U.S. 238 (1972).
[ Footnote 1 ] Section 26-1101 provides as follows:
[ Footnote 2 ] Section 26-3102 (Supp. 1975) provides:
[ Footnote 3 ] Section 27-2537 (g) provides:
[ Footnote 4 ] The court said:
[ Footnote 5 ] In a subsequently decided robbery-murder case, the Georgia Supreme Court had the following to say about the same "similar cases" referred to in this case:
[ Footnote 6 ] See Furman v. Georgia, 408 U.S., at 240 (Douglas, J., concurring).
[ Footnote 7 ] See id., at 306 (STEWART, J., concurring).
[ Footnote 8 ] See id., at 310 (WHITE, J., concurring).
[ Footnote 9 ] Petitioner also argues that the differences between murder - for which the death penalty may be imposed - and manslaughter - for which it may not be imposed - are so difficult to define and the jury's ability to disobey the trial judge's instructions so unfettered that juries will use the guilt-determination phase of a trial arbitrarily to convict some of a capital offense while convicting similarly situated individuals only of noncapital offenses. I believe this argument is enormously overstated. However, since the jury has discretion not to impose the death penalty at the sentencing phase of a case in Georgia, the problem of offense definition and jury nullification loses virtually all its significance in this case.
[ Footnote 10 ] The factor relevant to this case is that the "murder . . . was committed while the offender was engaged in the commission of another capital felony." The State in its brief refers to this type of murder as "witness-elimination" murder. Apparently the State of Georgia wishes to supply a substantial incentive to those engaged [428 U.S. 153, 222] in robbery to leave their guns at home and to persuade their co-conspirators to do the same in the hope that fewer victims of robberies will be killed.
[ Footnote 11 ] Petitioner states several times without citation that the only cases considered by the Georgia Supreme Court are those in which an appeal was taken either from a sentence of death or life imprisonment. This view finds no support in the language of the relevant statutes. Moore v. State, 233 Ga., at 863-864, 213 S. E. 2d, at 832.
MR. JUSTICE BLACKMUN, concurring in the judgment.
I concur in the judgment. See Furman v. Georgia, 408 U.S. 238, 405 -414 (1972) (BLACKMUN, J., dissenting), and id., at 375 (BURGER, C. J., dissenting); id., at 414 POWELL, J., dissenting); id., at 465 (REHNQUIST, J., dissenting).
MR. JUSTICE BRENNAN, dissenting. *
The Cruel and Unusual Punishments Clause "must draw its meaning from the evolving standards of decency that mark the progress of a maturing society." 1 The opinions of MR. JUSTICE STEWART, MR. JUSTICE POWELL, and MR. JUSTICE STEVENS today hold that "evolving standards of decency" require focus not on the essence of the death penalty itself but primarily upon the procedures employed by the State to single out persons to suffer the penalty of death. Those opinions hold further that, so viewed, the Clause invalidates the mandatory infliction of the death penalty but not its infliction under sentencing procedures that MR. JUSTICE STEWART, MR. JUSTICE POWELL, and MR. JUSTICE STEVENS conclude adequately safeguard against the risk that the death penalty was imposed in an arbitrary and capricious manner.
In Furman v. Georgia, 408 U.S. 238, 257 (1972) (concurring opinion), I read "evolving standards of decency" as requiring focus upon the essence of the death penalty itself and not primarily or solely upon the procedures [428 U.S. 153, 228] under which the determination to inflict the penalty upon a particular person was made. I there said:
This Court inescapably has the duty, as the ultimate arbiter of the meaning of our Constitution, to say whether, when individuals condemned to death stand before our Bar, "moral concepts" require us to hold that the law has progressed to the point where we should declare that the punishment of death, like punishments on the rack, the screw, and the wheel, is no longer morally tolerable in our civilized society. 4 My opinion in Furman v. Georgia concluded that our civilization and the law had progressed to this point and that therefore the punishment of death, for whatever crime and under all circumstances, is "cruel and unusual" in violation of the Eighth and Fourteenth Amendments of the Constitution. I shall not again canvass the reasons that led to that conclusion. I emphasize only that foremost among the "moral concepts" recognized in our cases and inherent in the Clause is the primary moral principle that the State, even as it punishes, must treat its citizens in a manner consistent with their intrinsic worth as human beings - a punishment must not be so severe as to be degrading to human dignity. A judicial determination [428 U.S. 153, 230] whether the punishment of death comports with human dignity is therefore not only permitted but compelled by the Clause. 408 U.S., at 270 .
I do not understand that the Court disagrees that "[i]n comparison to all other punishments today . . . the deliberate extinguishment of human life by the State is uniquely degrading to human dignity." Id., at 291. For three of my Brethren hold today that mandatory infliction of the death penalty constitutes the penalty cruel and unusual punishment. I perceive no principled basis for this limitation. Death for whatever crime and under all circumstances "is truly an awesome punishment. The calculated killing of a human being by the State involves, by its very nature, a denial of the executed person's humanity. . . . An executed person has indeed `lost the right to have rights.'" Id., at 290. Death is not only an unusually severe punishment, unusual in its pain, in its finality, and in its enormity, but it serves no penal purpose more effectively than a less severe punishment; therefore the principle inherent in the Clause that prohibits pointless infliction of excessive punishment when less severe punishment can adequately achieve the same purposes invalidates the punishment. Id., at 279.
The fatal constitutional infirmity in the punishment of death is that it treats "members of the human race as nonhumans, as objects to be toyed with and discarded. [It is] thus inconsistent with the fundamental premise of the Clause that even the vilest criminal remains a human being possessed of common human dignity." Id., at 273. As such it is a penalty that "subjects the individual to a fate forbidden by the principle of civilized treatment guaranteed by the [Clause]." 5 I therefore would hold, [428 U.S. 153, 231] on that ground alone, that death is today a cruel and unusual punishment prohibited by the Clause. "Justice of this kind is obviously no less shocking than the crime itself, and the new `official' murder, far from offering redress for the offense committed against society, adds instead a second defilement to the first." 6
I dissent from the judgments in No. 74-6257, Gregg v. Georgia, No. 75-5706, Proffitt v. Florida, and No. 75-5394, Jurek v. Texas, insofar as each upholds the death sentences challenged in those cases. I would set aside the death sentences imposed in those cases as violative of the Eighth and Fourteenth Amendments.

MR. JUSTICE MARSHALL, dissenting. *
In Furman v. Georgia, 408 U.S. 238, 314 (1972) (concurring opinion), I set forth at some length my views on the basic issue presented to the Court in these cases. The death penalty, I concluded, is a cruel and unusual punishment prohibited by the Eighth and Fourteenth Amendments. That continues to be my view.
I have no intention of retracing the "long and tedious journey," id., at 370, that led to my conclusion in Furman. My sole purposes here are to consider the suggestion that my conclusion in Furman has been undercut by developments since then, and briefly to evaluate the basis for my Brethren's holding that the extinction of life is a permissible form of punishment under the Cruel and Unusual Punishments Clause.
In Furman I concluded that the death penalty is constitutionally invalid for two reasons. First, the death penalty is excessive. Id., at 331-332; 342-359. And [428 U.S. 153, 232] second, the American people, fully informed as to the purposes of the death penalty and its liabilities, would in my view reject it as morally unacceptable. Id., at 360-369.
Since the decision in Furman, the legislatures of 35 States have enacted new statutes authorizing the imposition of the death sentence for certain crimes, and Congress has enacted a law providing the death penalty for air piracy resulting in death. 49 U.S.C. 1472 (i), (n) (1970 ed., Supp. IV). I would be less than candid if I did not acknowledge that these developments have a significant bearing on a realistic assessment of the moral acceptability of the death penalty to the American people. But if the constitutionality of the death penalty turns, as I have urged, on the opinion of an informed citizenry, then even the enactment of new death statutes cannot be viewed as conclusive. In Furman, I observed that the American people are largely unaware of the information critical to a judgment on the morality of the death penalty, and concluded that if they were better informed they would consider it shocking, unjust, and unacceptable. 408 U.S., at 360 -369. A recent study, conducted after the enactment of the post-Furman statutes, has confirmed that the American people know little about the death penalty, and that the opinions of an informed public would differ significantly from those of a public unaware of the consequences and effects of the death penalty. 1
Even assuming, however, that the post-Furman enactment of statutes authorizing the death penalty renders the prediction of the views of an informed citizenry an [428 U.S. 153, 233] uncertain basis for a constitutional decision, the enactment of those statutes has no bearing whatsoever on the conclusion that the death penalty is unconstitutional because it is excessive. An excessive penalty is invalid under the Cruel and Unusual Punishments Clause "even though popular sentiment may favor" it. Id., at 331; ante, at 173, 182-183 (opinion of STEWART, POWELL, and STEVENS, JJ.); Roberts v. Louisiana, post, at 353-354 (WHITE, J., dissenting). The inquiry here, then, is simply whether the death penalty is necessary to accomplish the legitimate legislative purposes in punishment, or whether a less severe penalty - life imprisonment - would do as well. Furman, supra, at 342 (MARSHALL, J., concurring).
The two purposes that sustain the death penalty as nonexcessive in the Court's view are general deterrence and retribution. In Furman, I canvassed the relevant data on the deterrent effect of capital punishment. 408 U.S., at 347 -354. 2 The state of knowledge at that point, after literally centuries of debate, was summarized as follows by a United Nations Committee:
The Solicitor General in his amicus brief in these cases [428 U.S. 153, 234] relies heavily on a study by Isaac Ehrlich, 4 reported a year after Furman, to support the contention that the death penalty does deter murder. Since the Ehrlich study was not available at the time of Furman and since it is the first scientific study to suggest that the death penalty may have a deterrent effect, I will briefly consider its import.
The Ehrlich study focused on the relationship in the Nation as a whole between the homicide rate and "execution risk" - the fraction of persons convicted of murder who were actually executed. Comparing the differences in homicide rate and execution risk for the years 1933 to 1969, Ehrlich found that increases in execution risk were associated with increases in the homicide rate. 5 But when he employed the statistical technique of multiple regression analysis to control for the influence of other variables posited to have an impact on the homicide rate, 6 Ehrlich found a negative correlation between changes in the homicide rate and changes in execution risk. His tentative conclusion was that for the period from 1933 to 1967 each additional execution in the United States might have saved eight lives. 7
The methods and conclusions of the Ehrlich study [428 U.S. 153, 235] have been severely criticized on a number of grounds. 8 It has been suggested, for example, that the study is defective because it compares execution and homicide rates on a nationwide, rather than a state-by-state, basis. The aggregation of data from all States - including those that have abolished the death penalty - obscures the relationship between murder and execution rates. Under Ehrlich's methodology, a decrease in the execution risk in one State combined with an increase in the murder rate in another State would, all other things being equal, suggest a deterrent effect that quite obviously would not exist. Indeed, a deterrent effect would be suggested if, once again all other things being equal, one State abolished the death penalty and experienced no change in the murder rate, while another State experienced an increase in the murder rate. 9
The most compelling criticism of the Ehrlich study is [428 U.S. 153, 236] that its conclusions are extremely sensitive to the choice of the time period included in the regression analysis. Analysis of Ehrlich's data reveals that all empirical support for the deterrent effect of capital punishment disappears when the five most recent years are removed from his time series - that is to say, whether a decrease in the execution risk corresponds to an increase or a decrease in the murder rate depends on the ending point of the sample period. 10 This finding has cast severe doubts on the reliability of Ehrlich's tentative conclusions. 11 Indeed, a recent regression study, based on Ehrlich's theoretical model but using cross-section state data for the years 1950 and 1960, found no support for the conclusion that executions act as a deterrent. 12
The Ehrlich study, in short, is of little, if any, assistance in assessing the deterrent impact of the death penalty. Accord, Commonwealth v. O'Neal, ___ Mass. ___, ___, 339 N. E. 2d 676, 684 (1975). The evidence I reviewed in Furman 13 remains convincing, in my view, that "capital punishment is not necessary as a deterrent to crime in our society." 408 U.S., at 353 . The justification for the death penalty must be found elsewhere.
The other principal purpose said to be served by the death penalty is retribution. 14 The notion that retribution [428 U.S. 153, 237] can serve as a moral justification for the sanction of death finds credence in the opinion of my Brothers STEWART, POWELL, and STEVENS, and that of my Brother WHITE in Roberts v. Louisiana, post, p. 337. See also Furman v. Georgia, 408 U.S., at 394 -395 (BURGER, C. J., dissenting). It is this notion that I find to be the most disturbing aspect of today's unfortunate decisions.
The concept of retribution is a multifaceted one, and any discussion of its role in the criminal law must be undertaken with caution. On one level, it can be said that the notion of retribution or reprobation is the basis of our insistence that only those who have broken the law be punished, and in this sense the notion is quite obviously central to a just system of criminal sanctions. But our recognition that retribution plays a crucial role in determining who may be punished by no means requires approval of retribution as a general justification for punishment. 15 It is the question whether retribution can provide a moral justification for punishment - in particular, capital punishment - that we must consider.
My Brothers STEWART, POWELL, and STEVENS offer the following explanation of the retributive justification for capital punishment:
In a related vein, it may be suggested that the expression of moral outrage through the imposition of the death penalty serves to reinforce basic moral values - that it marks some crimes as particularly offensive and therefore to be avoided. The argument is akin to a deterrence argument, but differs in that it contemplates the individual's shrinking from antisocial conduct, not because he fears punishment, but because he has been told in the strongest possible way that the conduct is wrong. This contention, like the previous one, provides no support for the death penalty. It is inconceivable that any individual concerned about conforming his conduct to what society says is "right" would fail to realize that murder is "wrong" if the penalty were simply life imprisonment.
The foregoing contentions - that society's expression of moral outrage through the imposition of the death penalty pre-empts the citizenry from taking the law into its [428 U.S. 153, 239] own hands and reinforces moral values - are not retributive in the purest sense. They are essentially utilitarian in that they portray the death penalty as valuable because of its beneficial results. These justifications for the death penalty are inadequate because the penalty is, quite clearly I think, not necessary to the accomplishment of those results.
There remains for consideration, however, what might be termed the purely retributive justification for the death penalty - that the death penalty is appropriate, not because of its beneficial effect on society, but because the taking of the murderer's life is itself morally good. 17 Some of the language of the opinion of my Brothers STEWART, POWELL, and STEVENS in No. 74-6257 appears positively to embrace this notion of retribution for its own sake as a justification for capital punishment. 18 They state:
The death penalty, unnecessary to promote the goal of deterrence or to further any legitimate notion of retribution, is an excessive penalty forbidden by the Eighth and Fourteenth Amendments. I respectfully dissent from the Court's judgment upholding the sentences of death imposed upon the petitioners in these cases.

Roberts v. Louisiana, post, at 354. (WHITE, J., dissenting). But MR. JUSTICE WHITE later states: "It will not do to denigrate these legislative judgments as some form of vestigial savagery or as purely retributive in motivation; for they are solemn judgments, reasonably based, that imposition of the death penalty will save the lives of innocent persons." Post, at 355.
