I agree with the Rock´s decision to leave. He was asked to do a lot of nasty things and I think Dwayne Johnson realised how badly his reputation could suffer if he carried on humiliating people, assaulting people, before he beat them in wrestling matches. There´s a fine line between acting like a heel and being the whipper of the company and the Rock didn´t cross it. Better to work as a varied talent, than to be a stereotypical villain who will do nothing but the worst to everyone for the sake of the company´s well-being.
