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.
It's a character that I always found really likable. I'm fond of Zorro because he was a popular figure who worked for the people.
In the main it will be found that a power over a man's support (salary) is a power over his will.
