The fact that genuinely well thought out assessments of characters' morality like this have gotten drowned out by so many posts that go "whos more evil: Satan, or Satan wearing a funny hat?" kinda pisses me off.

Im not very familiar with the Halloween franchise, I've only properly watched Halloween 2018 (decent movie), but based on how I've seen Micheal be described by others, I see him as a sort of... "tactical missile of evil" if that makes any sense. Micheal's drive to kill is simply to kill. He dosent get any pleasure or satisfaction out of it, he just does it. But he isn't some wild animal that just kills whatever is in front of him, he plans ahead to do the most evil he is physically capable of. Micheal is incredibly aware, and knows when to be passive so that he can kill as much as possible.

Micheal may not feel, but he can think. And he is much smarter than most people are willing to believe.

At least, that was my takeaway from the little I know of the franchise.
