One good thing about him spending the rest of his sorry a** life in prison. He would lose weight. I expect he can't get his tummy filled 24/7. I expect there is a certain amount of food allowed the inmates. I expect he would try to bribe the guard to get him cheeseburgers and chocolate cake but they would not roll over for him.
So health-wise prison would do him a lot of good. Upside. Of course he would live a very solitary life to protect his life so that an anti-duck wouldn't try to "take him out". No twitter no tweets no press conferences no book deals no calling in to TV or radio shows. Deadly silent. No communication forever more with the outside world.
He doesn't read. If they gave him a TV he could watch 24/7. He just couldn't contact anyone about anything at any time.
