I think it's just a case of him looking out for number one, and not having the backbone to go about things in the right way and say how he really feels/felt.
Which makes him no different from the average top-flight footballer to be honest - although i would add my usual caveat in that most other footballers who shafted their clubs for another didn'yt go to the extent of writing a book declaring their undividing love for their former club
We all thought Torres to be different - hence the intense dislike for his treachery
Also, whilst Torres has been at hids ineffective wirst throhyghout his miserable stint at Chelsea, it's not for lack of effort on his part
He loves Chelsea, his new surroundings, his teammates like Tery and Cole, and the Nazi-supporting vermin that make up the bulk of their support - whereas at Liverpool, he didn't have any time for his teammates, never turned up to any of the club's bonding sessions, saw training as too serious and didn't give a f*** about the fans - as evident in his submission of a transfer request once he heard news of Chelsea's interest
