I haven't killed a player in a while now, the first time i did i was just wandering along the coast line and i see a guy come running at me with a pack of z's behind him, so i start running we keep running for a while. Eventually i think i'm gonna turn around and kill these z's, so i turned around and aimed, shot and started running again and i started to not hear the z's so i look behind me and i had shot the survivor by mistake they we're eating his corpse. I felt horrible for a while after that.
