Justice isn't about what society is best served by. It's about.....punishing the transgressor. We're super lucky he's still alive so we can lock him up.The argument is more about what society gets out of him being free vs. him being in prison. No one's saying he's a good person.
If he's out he does what he can at his age to shut down holocaust deniers.
Throw him in jail and everyone feels good for 5 seconds because "justice prevailed".
I think we benefit more from scenario A, but again, it's not an argument I'm super passionate about.

"well society would be better served if he gave motivational speeches to first graders!!!"
