In an average year, about 20,000 homicides occur in the United States. Fewer than 300 convicted murderers are sentenced to death. But because no more than thirty murderers have been executed in any recent year, most convicts sentenced to death are likely to die of old age. Nonetheless, the death penalty looms large in discussions: it raises important moral questions independent of the number of executions. The death penalty is our harshest punishment. It is irrevocable: it ends the existence of those punished, instead of temporarily imprisoning them. Further, although not intended to cause physical pain, execution is the only corporal punishment still applied to adults. These singular characteristics contribute to the perennial, impassioned controversy about capital punishment.Consideration of the justice, morality, or usefulness, of capital punishment is often conflated with objections to its alleged discriminatory or capricious distribution among the guilty. Wrongly so, if capital punishment is immoral, no distribution, cannot affect the quality of what is distributed, be it punishments or rewards. Discriminatory or capricious distribution thus could not justify abolition of the death penalty. Further, misdistribution inheres no more in capital punishment than in any other punishment.Misdistribution between the guilty and the innocent is, by definition, unjust. But the injustice does not lie in the nature of the punishment. Because of the finality of the death penalty, the most grievous misdistribution occurs when it is imposed upon the innocent. However, the frequent allegations of discrimination and capriciousness refer to misdistribution among the guilty and not to the punishment of the innocent.Misdistribution of any punishment among those who deserve it is irrelevant to its justice or morality. Even if poor or black convicts guilty of capital offenses suffer capital punishment, and other convicts equally guilty of the same cri...
