When writers give a villain a completely
sound motivation/or just makes them right and then is forced to make them do
something horrible to get you to not sympathize with them.
How do you make a Holocaust survivor who doesn’t want his
people genocided AGAIN, into a villain? The Magneto Effect.
Humanity: Builds weapons of mutant
genocide
Magneto: I don’t like that
Humanity: What a
monster!?!?
