Even among Batman's other rogues, Blackfire comes across as scum. He's responsible for countless deaths and mass destruction designed solely to fuel his own immortality spa treatment (honestly, forget the blood--hasn't this dude ever heard of a Lazurus Pit?), is one of the few villains to ever bring Batman down to the point where he breaks his code, and on top of that--like most cult leaders--he's a cowardly bastard who targets those weaker than him and runs with his tail between his legs when faced with someone he can't forcibly control or manipulate. Plus, since his immortality is up for debate, it can be argued that he has far less resources than the likes of Joker, Ra's al Ghul, etc, since he only ever used his charisma and brainwashing methods to amass his large following.

So, I think I'm leading towards a yes.
