I agree with you, Tosh.
I don't know that there is much point doing anything to the old monster. Maybe hang a sign around his neck, give him a begging basket, and turn him loose. But, really, I don't truly think there's any point. We might all feel a bit of some kind of satisfaction if we punish him, but there is NOTHING that will make him like us and nothing can undo what he did.
Is he "insane"? I don't know what the legal definition of insanity is in Austria. The elaborate plans, etc., do not make me think he's "not" insane. In some ways they prove he's as loony as can be. In other ways, he's "sane", in that he is acting out of what he is and undoubtedly always has. Some people seem to be born that way, and some of those people are brought up in ways that exacerbate their sociopathy. This man lived through WW II. Who knows what he might have seen or done, maybe worse things. Maybe awful things happened to him. I'm not "excusing" him, but trying to understand.
I don't want to sound callous, but in all honesty it would have been better if the whole clan had died. Who knows what monstrous things he's created? I know that's a dreadful thing to say and now that they are out and trying to live in the world I think everything should be done to help them.
The only thing we can do, as decent people, is to keep him locked up and to treat him humanely. To do otherwise is to let our side down. We are obligated to act properly and if that means that he lives in comfort, so be it. We can't possibly punish him in any meaningful way and we shouldn't even try.
