100% would have to pick red for no one to die. 50.1% would have to pick BLUE for no one to die. Functionally, the blue button does nothing or kills you, the red button does nothing (only if 100% pick it) or kills every single person who chooses differently. Personally I'd pick BLUE if for no other reason than that I'd rather die then live in a world where more than 50% pick red.
