12. Well you'd essentially be deconstructing MC

Tearing them down with his own slow moral decline based on choices he thinks will improve his life.

You'd have to write the new character so that she becomes the favorite. She's smarter, more mature, more at peace, kinder, and fiercer. When she leaves never to return, the audience wants her back.

But she doesn't. They're stuck with the MC. He has to rebuild himself anew in order to get them to stick around. But it will be hard because the audience agrees with the girl.
