“Only one man knows more secrets of black magic than I do! And he is the one who taught me years ago — he is the master!! But the time has come for me to wrest those secrets from him! For it is I, Baron Mordo, who must be the most powerful magician of all! “

I don’t know if sorcerers have arch-enemies exactly but in the Marvel universe Baron Mordo is definitely the anti-Dr. Strange. They were rivals for title of Sorcerer Supreme and since Mordo lost out he gets to be the ‘evil’ one. And while the cinematic version seems a bit more sympathetic than his comic counterpart, you can’t go around crippling people and not be considered the bad guy.
