I probably didn't see him as an ultimate bad boy with a good heart. Rogue married him though and had a son. I guess the diff with Charles and Erik was that Charles wanted humans and mutants to be equal, whereas Erik was always on the side of the mutants, be it mutants being superior to humans, or when mutants are attacked, off to their rescue. Charles did ask Magneto to run X men at some point, i think when Jean killed him ? Charles and Magneto have this love hate friendship all throughout.
