"The crimes of rape, torture, treason, kidnapping, murder, larceny, and perjury pivot on a moral code that escapes apodictic [indisputably true] proof by expert testimony or otherwise. But communities would plunge into anarchy if they could not act on moral assumptions less certain than that the sun will rise in the east and set in the west. Abolitionists may contend that the death penalty is inherently immoral because governments should never take human life, no matter what the provocation. But that is an article of faith, not of fact. The death penalty honors human dignity by treating the defendant as a free moral actor able to control his own destiny for good or for ill; it does not treat him as an animal with no moral sense."
