It’s not really constructive to talk about “punishing” an Albert Fish (Jeff Dahmer, etc.). Punishment is something we mete out in hopes that that it will either (1) persuade the person being punished to not repeat the offensive behavior, or (2) provide some manner of compensation to that person’s victim(s).
Say, for example, that Jim undertakes to spray paint Ed’s house with a statement that combines an ethnic slur with language suggesting that Ed’s family leave forthwith or risk losing their lives. Removing the graffitti will cost Ed quite a bit of money, and Ed’s family endures considerable fear and anxiety until Jim is identified and arrested. We may punish Jim in any of several ways, such as:
(1) We may put him in prison, in hopes that he will find the experience sufficiently unpleasant that he will avoid behavior that will put him in jail again;
(2) We may compel him to attend some manner of training or counseling, in hopes that he will understand the harm that he inflicted on Ed’s family and thus refrain from acting in such a manner again;
(3) We may compel him to make whole Ed’s property by either removing the graffitti himself or by paying for its removal, in hopes that this brings some relief to Ed and his family (it may also be unpleasant enough to persuade Jim not to commit similar acts in the future).
This only works if Jim agrees that prison time/a big fine/Ed’s distress, etc. is not a fair price to pay for the temporary pleasure of vandalising Ed’s house.
An Albert Fish doesn’t function that way. He’s probably not particularly upset at the prospect of going to jail or of dying. He has no empathy for his victims. He may even regard himself as a victim, insisting that he’s been wronged by his arrest and conviction. Nothing will persuade him to change his behavior, so you can’t really speak of “punishing” him.
It’s more constructive to ask, “How does society *manage *someone like Albert Fish?” Do we lock him up for the rest of his natural life in order to prevent him from harming any more people? Do we decide that he’s such a risk to others (even if incarcerated) that we should simply end his life?
I can’t support the notion of torturing someone like Fish in order to provide “closure” to his victims or their families. If we agree that he’s such a danger that he can’t be incarcerated, he should be euthanized. Because really, that’s what we’re saying - this creature is so damaged that we can’t justify keeping him alive, any more that we can justify keeping a rabid dog alive. Making him suffer does nothing to make anyone safer, doesn’t bring back the dead, and probably doesn’t grant long-term comfort to the survivors. It’s a perverse form of entertainment for the living, nothing more.
