Magneto has a whole lot of complexity to him. Emotionally, he's coming from a very damaged place. I like the ambivalence of it. I want the audience leaving the theater wondering, asking the questions themselves rather than being spoon-fed like a lot of these super-villain characters.
But go on, valiant champion; you die not as a fool, though the apostate, unfaithful, and lukewarm ministers and professors of this generation think and say so.
