Thinking on it. Killing a killer, you are just as bad. God invokes the punishment to his rules. He says "You murdered, you broke the fifth commandment, to Hell with your soul". It is not our place to break a commandment in responce to the breaking of a commandment. It is Gods place to punish those who break his commandments, not ours.

Plus even more, that is religous view, not really the view government should look for. The worst punishment possible is to let them rot in jail.
