Here's how it goes. You have been attacked by a robber or serial killer. He is attacking you and your family and you see a knife and he is distracted. Would you? Personally, I would. I mean it's for the protection of my family and self defense. That person would have robbed me of everything I have because he's some pathetic deranged excuse of a human being. I think all of us here would so the same thing to protect. The Sick bastards that kill for the game and pleasure deserve to die. Those are the worst in the world and they shouldn't deserve to live. Alright so let's say you did kill him. Would you be tried in a court for the murder?
