I see your point but for a man who imposed his choices on others and robbed them of theirs I’d like him to experience helplessness. And I don’t think it’s fair to ask the other inmates or guards to do that for us, further brutalizing their own souls.
Of course, he’s already mentally locked in to the “I’m the only victim here” mindset. Nothing will change that, so I guess all we can do is keep him out of the lives of the survivors.
