Body horror galore. Going a little less extreme, I think the guy just needs a proper wrangler that tells him "NO!" and distracts him in a way that doesn't end with him hurting himself or somebody else.It seems the consensus here is that Nolan doesn't deserve freedom, and I happen to think that there's something to that.
His hands and feet should be amputated, being replaced with horse hooves, so he can become productive. His face will be muzzled so that he can't distract himself by talking.
Nolan can live his life as a beast-of-burden. Using his immense strength to haul carts of wood day-after-day, with the only things offered as rewards being food and new Gura merch.
I think this will lead him to a more peaceful existence.
I think they had professions and institutions for those sorts of problems, but I could just be imagining things.
