" Now, on the subject of deterrence, I admit that there can be little doubt that as presently administered in the United States, the death penalty is not a general deterrent to murder in many, if not most, situations. . . .

But of one thing I am certain: it is, by God, a specific deterrent. No one who has been executed has ever taken another innocent life. And until such time as we really mean it as a society when we say ‘imprisonment for life,’ I, and the families of countless victims, would sleep better at night knowing there is no chance that the worst of these killers will ever again be able to prey on others. Even then, I personally believe that if you choose to take another human life, you ought to be prepared to pay with your own. "
