Murder Drones PTSD

So this is a murder drones story with an OC I made being john, he is a war veteran (this is if cyn never existed) from the human vs worker war of 3050 and the workers won, he is the last veteran from the war. V shoots him in the shoulder and his PTSD goes off and makes him go on a killing streak, a war breaks out where every drone, disassembly or worker team up to stop him, you can make him snap out of the PTSD or kill him it doesn't matter to me, however if you try to kill him at the beginning it will somehow miss, since you can't kill someone right when the action starts rising.
