Bendis will ignore that. He is the head archetict of Marvel. Beside that, I don't like the idea of a White Mage like Doctor Strange using dark arts that have staggering consequences.
I've never really seen Strange as any kind of white wizard. He is (or was - not sure if he is again or not) the Sorcerer Supreme, a guardian of his realm. It's not necessarily good or evil, imo. If he needs to play dirty to do his job in a time of crisis, I think he would. What I mean is that he's not morally superhuman. He's a normal, good person with a big job that brings him up against some big evil, but fighting evil doesn't make you absolutely good.
