I think with good behaviour he will get moved out of solitary and into a cell block with a bunk mate.
If he continues to be a good boy he might even qualify for parole in 15 or 20 years after everyone has forgotten about him.
He doesn't think he will go to Hell as long as he has his Koran, prayer mat, prays the five, and eats hallal.
For living under the chains of the infidel he might even get a special commendation by Allah herself for staying faithful even in solitary.
Nope, his sentence is permanent supermax, 23 hours a day isolation, 1 hour of exercise by himself. There is no "general" population or visitors for him to mix with. Now that is not to say that some future rat-party judge or president couldn't commute or change that sentence to allow him into a general population or even pardon him, but the idea is to turn him into a drooling demented mess through isolation. Rather see him wrapped in pigskin and hanged publicly, but that isn't going to happen now so this is the next best thing.
