I like that Idea Tadanori!
He could try to "refine" you, and keep you on the morale path, and use your character to keep himself from succumbing to those same powers he considers to be evil.
My character is quite honest, and doesn't really care about other people's personal opinions, more suited to ordering and leading than following, though he doesn't just order either, he likes to lead by example, being the first into the fray.
