Cody will compromise his ethics, do something very heelish, or become outright evil before he will win the Undisputed Title. He will do a promo talking about how he is now only wrestling for himself instead of "you people" and will verbally bury the audience. This is the only way anyone ever gets to be a main eventer in Vince McMahon's WWE.
Vince despises good guys, both on-screen and in real life.
