If he was flawed and weak, but yet powerful… only missing some self knowledge, he would have made a good anti hero. Giving it more of an interesting twist. But yeah he couldn’t overcome himself.

I think anti hero path would be okay too but given the number of atrocities committed, and the nature of their battle, it's hard for me to believe that things will just work out and every one gets a happy ending. Reality tends to be more cruel and unforgiving.
