I never used to when I started playing, I though I was awesome getting a kill at all. Since I've played for a while now, Im going to not kill unarmed players, because its not satisyfing and especially annoying for that player. It takes a while to load the game, and I know how much it annoys me. I will usually attempt to kill players of equal power or more, but avoid unarmed players. if they come up to me and ask for stuff, and dont leave, I'll ask them too, If they dont they get shot. I dont want anything being stolen from me.
