I don't see much logic behind capital punishment. Wouldn't someone who is irrational enough to take another humans life in a pre-meditated way not value their own much? Maybe after the fact they regret it and fear death but it's already too late. The risk of executing any innocent person is so incompatible with basic human rights that whatever joy the victims family gets out of a revenge killing simply isn't worth it. I'm also a bit terrified by the radical Christian fundamentalists that can somehow rationalize taking another humans life in this context. It's far too close to the mindset of a suicide bomber who can twist religion into being compatible with their own hatred and anger.
