I've seen a few movies with killing in it. I don't know if this is a good question, but I was wondering, how do people kill someone and not few the shame. I mean, lets say I had to kill someone to protect my family, I would feel like I've commit something that I couldn't live with. Do soldiers feel bad when they kill? How do you protect your family to a point that includes taking someone's life and not feel guilty?
Of course, not that I'm going to kill someone...
