It's actually kind of sad that crazy, scenery-chewing, megalomaniacal comics Erik is fundamentally a better person than any movieverse version. Because when comics Magneto does the most truly awful things that he does, he is obviously off his rocker, and when he gets his head under control, he's often either outright a good person, or at least a manipulative Magnificent Bastard that's no worse than Charles is. Whereas movie Erik doesn't have that excuse. He's in his right mind most of the time when he does terrible things.
