He must have grown up thinking that he was a cute kid, since everybody said so, but even so he must have thought that he would have been a lot cuter if he had been white. So he tried to become white through the aid of plastic surgery, but he only ended up looking weird and sick that way.
I always heard that the change in his skin color was due to a rare skin disease--I don't think it's possible to change skin color through plastic surgery.
