It would have been more emotionally satisfying to see him get dead.
I got the impression that the outcome he prayed for was to be executed, so he could be a glorious martyr and get 72 virgins in heaven.
Now, he gets to spend the rest of his twisted life as a captive of those he hates most in the world, and now he's no martyr...just a loser.
I hope the sentence leaves him suffering, broken and miserable. His mother must be so proud.
