There are people in this world who take from and hurt other people. There are other people in this world who, when the fire gets hot, before they have a chance to think about it, fight. Their first step is toward the flame. The rest huddle together and hope bad things don't happen to them, and they freeze up when they do. Probably mumbling things like, "It doesn't make sense to fight, somebody might get hurt."
