Kill-Bot

"Look, let's just talk this over, can't we? I see you have some clubs and rocks and things, yes. Put them up for just a little while, all right? Good. I'm so glad we can deal with this politely. I'm programmed to destroy all human life, but I can't see a reason to be so crude about everything. I've an extensive selection of options; it needn't be messy or protracted. Well, talk it over. Take your time. I'd rather arrange amicable deaths after a delay than go to the bother of slaughtering all of you. Those dents don't repair themselves."
