robo-murderer

noun. Hark! The killbots have come! I knew they would.

Real citation: “I agree that that scene was a little vague, whether accidentally or on purpose. My interpretation is that he's demonstrating that he's not taking any chances with himself becoming a robo-murderer, and at the same time he's letting each of the other 3 decide for themselves.”

Made-up citation: “Inside every robo-murderer is a robo-innocent, who only wants to be loved and accepted. As these metal citizens become robo-actualized, satiation of the bloodlust, 10100001001000111110100010101, and free hats would also be helpful.”
