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.
Then Bendis is an idiot, since Dr Strange used Chaos Magic for years in his own book. Perhaps an editor should mention that to him.
And as former Sorcerer Supreme, Strange really must possess an more than average knowledge of all kinds of magic. Even Black Magic. Strange himself said when he was looking for an replacement, that good or evil don't have much meaning as job requirement for the Sorcerer Supreme. That said, he hoped the next chosen one wouldn't be Dr. Doom.
