I don't hate him.
He left Arsenal to join Chelsea, presumably for trophies. Ok he's on more money but then so is Ade. Tevez, Lescott, Barry. I'm not into this labelling of any player a 'mercenary', I find it cretinous, hypocritical and slightly mard.
He's got a very fit wife, well played to him. Doesn't bother me either way but nice one for him. He cheats on her, well again, none of my business.
So, in summary, Ashley Cole - Same as every other footballer. Just the media tell us to hate some and love others.
