Magneto has flipped quite a few times, and I've read nearly all of them up to the '90s or so when I got tired of X-comics. Magneto is truly one of the most interesting characters in that 'verse.

With Logan, Loki and other characters, we see that morally ambiguous or mutable is actually something movie goers and comic fans like. Mags has been evil and not so evil in the current movies; why would that change and why would the character care, if I'm reading him right?
