I dont hate him, some peeps just dont take to boxers. I dont like Mayweather, but I do respect his skills and achievements.

A good thing for Khan, when he got KO'd he knew he had to change everything about his training and prep for fights, and realised if he wanted to get to the big time he needed to change.
So he left home and uprooted himself to the US and joined the Roach clan. Best and most mature thing to do. He's reaping the benefits of this, and good on him.
