Michael Myers has always been depicted as resistant to damage/superhuman; between Halloween 1, 2, and H20, he survived being stabbed in the chest, 6 shots to the chest, falling from a 2nd story window, and an explosion, among other things. In addition, according to Horror Film Wiki, "He also seems to be able to regenerate lost tissue, as in Halloween II Laurie shoots out his eyes, and in both the timelines that follow his vision is as good as ever."

He's never been "just a normal guy who's psycho".
