Yeah, I know. That's why I asked here first since there are those reasons. And the biggest reason is that da Vinci is not a hero.

But the real Cao Cao doesn't seem to be a hero to me the way Azazel explained it. And also, IMO, it will be contradicting if the leaders or the main members of the Hero faction are not heroes.
