He was pretty evil in TOS when you think about it and take him literally. He was a human trafficker after all.
The guy who has one robot peacefully take over a ship then maroon the crew on a planet where every need of theirs will be met (and is defeated by pantomime) is the same guy who
goes out of his way to murder members of the crew of a starship as many times as possible, then destroying the ship on the off chance he’ll be able to commit the perfect crime
is just jarring to me.
