Testimony in Favor of the Death Penalty
Execution of those who have committed heinous murders may deter only one murder per year. If it does, it seems quite warranted. It is also the only fitting retribution for murder I can think of.
Most abolitionists acknowledge that they would continue to favor abolition even if the death penalty were shown to deter more murders than alternatives could deter. Abolitionists appear to value the life of a convicted murderer or, at least, his non-execution, more highly than they value the lives of the innocent victims who might be spared by deterring prospective murderers.
Deterrence is not altogether decisive for me either. I would favor retention of the death penalty as retribution even if it were shown that the threat of execution could not deter prospective murderers not already deterred by the threat of imprisonment. Still, I believe the death penalty, because of its finality, is more feared than imprisonment, and deters some prospective murderers not deterred by the thought of imprisonment. Sparing the lives of even a few prospective victims by deterring their murderers is more important than preserving the lives of convicted murderers because of the possibility, or even the probability, that executing them would not deter others. Whereas the life of the victims who might be saved are valuable, that of the murderer has only negative value, because of his crime. Surely the criminal law is meant to protect the lives of potential victims in preference to those of actual murderers.

We threaten punishments in order to deter crime. We impose them not only to make the threats credible but also as retribution (justice) for the crimes that were not deterred. Threats and punishments are necessary to deter and deterrence is a sufficient practical justification for them. Retribution is an independent moral justification. Although penalties can be unwise, repulsive, or inappropriate, and those punished can be pitiable, in a sense the infliction of legal punishment on a guilty person cannot be unjust. By committing the crime, the criminal volunteered to assume the risk of receiving a legal punishment that he could have avoided by not committing the crime. The punishment he suffers is the punishment he voluntarily risked suffering and, therefore, it is no more unjust to him than any other event for which one knowingly volunteers to assume the risk. Thus, the death penalty cannot be unjust to the guilty criminal.
