This is why Magneto is my favorite villain.
Many heroes have a story behind them explaining why they are heroes. I don’t mean why they have super powers, I mean what made them into a hero.
Many villains lack that, but not Magneto.
You can follow his life history and really understand how he became the man he is.
Now would I join Magneto? No.
He isn’t much different than the Nazi’s who placed him and his family in Auschwitz.
