No one's trying to force you to kill anything. But around here, someone has to do it to keep people from getting killed needlessly. Sometimes it gets to the point where it's flat out kill-or-be-killed, sometimes it's kill-or-watch-your-friends-die. It'd be cool if we got stuck in a world where everyone and everything got along, but we didn't. I kinda doubt that a world like that exists. But this is probably one of the more screwed up worlds out there, or it seems like it, at least.
