It shouldn't matter if he got screwed, hes a piece of shit who killed 36 people, he got a taste of his own medicine. If he would of just being an actual cooperating witness instead of fighting the gov he could of been out but he had to be the boss still and start saying Sammy dealt drugs and all. There is no doubt in my mind he would of continued a life of crime on the outside, him and Gravano are exactly where they need to be.
