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.
In the First World War, there was the sudden passion of nationalism, and the killing took place because of these emotions. But the Soviet case is different, because you had systematic murder, like the Holocaust.
I look for these qualities and characteristics in people. Honesty is number one, respect, and absolutely the third would have to be loyalty.
