The Rock has nothing to owe the WWE, he wanted to do something else away from wrestling, is there anything wrong with that? No, he left the business when he was still pretty young age and didn't try pushing past his prime like Hogan, i guess Cena finds something wrong with that, seeing he probably won't be able to do anything when he leaves the WWE, i mean he's supposed to be the "face" of the WWE and half of the time he gets booed, and his movies suck, and a failed rap artist on top of that. The Rock established himself as something different than "A wrestler" and his credited in his movies as "Dwayne Johnson" now i believe, and it was the fans who made him who he is today and to us he'll always be "The People's Champion, and i believe it's the other way around for Cena, the company is making him who he is, not the fans.
