Fair enough. But you would personally "execute" (in self defense, but execute nonetheless) someone before he committed murder. How do you know for sure he was going to murder your child? He may have had no real intention to do it, so you would have killed a man who was only there to rob you. You would not allow the state to do it after he committed murder. It is infinitely worse after he committed the act. Why do you think you deserve the power of God but the state doesn't deserve it?
