All robots in WALL·E follow the Three Laws of Robotics, originally conceived by sci-fi writer Isaac Asimov (A robot may not injure a human being or, through inaction, allow a human being to come to harm; a robot must obey the orders given to it by human beings, except where such orders would conflict with the First Law; a robot must protect its own existence as long as such protection does not conflict with the First or Second Laws). Several bad bots have dilemmas in following those laws.
I have a feeling that this was just coincidence…
