Anyone who's actually disgusted by Cena as a person needs to have their head checked. He's nowhere near my favorite wrestler (I believe I've yelled, ‘Cena sucks!’ at an event or two), but this is a man who has granted the most Make-A-Wishes in the history of the organization, he supports numerous charities and, by all accounts, he's an excellent dude in person. So, if we're talking about him in reality, he doesn't deserve any hatred.

Now, John Cena the character/wrestler? He most certainly does. It is important to remember that he's mostly doing what he's told to do when in front of the camera or ring. So your beef might be more with WWE's creative team than it is with Cena.
