I think the point of chango's Jesus reference was to the effect that this is a largely christian country and he preached loving your fellow man and, most importantly, forgiveness. He also used a metaphor about turning your cheek to one who struck one side of your face. So if one is a follower of Jesus one would be more inclined to forgive the rapist murderer and if carried to its extreme in the teaching of Jesus, hand over some more victims.
I don't pretend to understand exactly what Jesus was trying to say and perhaps he was preaching a Ghandian ethics where you willingly die rather than retaliate.
I don't want to live in a society like that because it would be a purely big-ones-eat-the-little-ones world and the scum would always rise to the top.
I do respect the sentiment however. I just don't indulge it myself
Torturing people while executing them is pretty terrible and should not be condoned. But keep in mind that the purpose of lethal injection was to lessen the cruelty and chances of pain. I have yet to learn why the state, in its infinite wisdom, can't just inject the murderer with an overdose of morphine and make his last moment one of joy.
As for life imprisonment, I have no problem with it and would suggest that a cell with The Complete Montaigne and basic cable would be a good way to treat the condemned to life prisoner. No Longhorn Network.
