Come to lit club! I'm sure we can find a way to work in the villain angle... Morgan could be mentoring Michi at school, and then when Michi Awakens he realizes how pre-ordained his life is (or how drawn to evil he is? idk the canon), that even with a clean start he got himself into the same situation...

Or at least similar: While Rosiel is as unscrupulous as they come, he's a villain of circumstances, not a villain at heart.
