There are some very good reasons why even the guilty should not be punished with death (see my article in Philosophy Now mag) but I will not recite these here. Rather, I want to point out that Christian orthodoxy maintains that the entire human race is guilty by virtue of our 'fallen' relationship to Adam & Eve, whose original sin has tainted us. The modern notion that we are personally responsible for our own moral status is alien to the Christian worldview. Adam's sin is responsible for our inherently evil nature, and Jesus's sacrifice is responsible for our salvation. We are mere spectators in the cosmic morality play in which our own free will has no impact on our situation.

If Adam and Eve sinned against God, then it seems to me that they, just like the modern death row prisoner, are the ones who ought to be punished. It makes no sense to say, on the one hand, that Adam is guilty because he abused his free will, and that we are also guilty even though we did not. Either what makes someone morally guilty is that they freely choose a wrong act, or they are just bad by design, in which case we ought to blame the designer. Now, if Adam sinned because of a bad design, then the buck stops with God, who made him badly. If not, then I'm afraid he is responsible and not me, nor you, nor anyone else who didn't partake of the sin. That is human logic folks, and it always seems to ring the death bell to Christian fundamentalism's contradictions.

According to the strictly orthodox Christian logic, all babies ought to be aborted, because like the fellow on death row, they are guilty.
