They are both world conquerors that seeks to destroy anyone who tries stand in their way. Though they have different reasons to be world conquerors like with Magneto's belief. He believes that mankind doesn't want mutants, because they see them as an illness; a disease, which in contrast with Magneto: he believes mutants are the evolution; God's gift to His very children and Magneto is trying to protect that gift by fighting the MRD and making Genosha. Dr. Doom is the real evil though despite as how Stan Lee once pointed out, he's a king of his own country and thus it would be impossible to even legally label him as a villain.

In other words, Magneto may do things too aggressionally but he's only doing something that was the only way he felt was right. So, it's kind of hard to call him a legit villain.
