Out of all the reasons for Cena turning heel, having him brainwashed by the Wyatts is pretty silly. Much like how the Wyatts seemingly brainwashed Daniel Bryan into joining the family, nobody would really buy that such a positive thinker, a man who lives on hustle, loyalty, and respect, would be convinced by Bray Wyatt to join him on the path to destroying all of the worlds heroes. Its not natural, and it comes off as cheesy soap opera. It wouldnt be the first time WWE has gone in that direction, but it would be nice if it was avoided. Instead, Cena needs to choose to change his ways. The audience needs to understand that Cena being a heel is not due to the mind control powers of a redneck cult. For whatever reason, Cena has decided to turn his back on the WWE Universe, and for the move to be effective, the fans have to believe in Cenas reasons and not rely on the off chance that Cena can be saved and be brought back to the side of good. It would be easy to say that Cena was mind controlled, but heres hoping that the writing team have something more interesting, and a tad more believable, in mind for Cenas heel turn should that day ever come.
