Problem not solved, in my opinion. The second pedophile is already unable to molest children, and adding severity to punishment isn't as effective as adding immediacy or certainty.
The problem is solved by pairing those who wish to live longer at personal cost to themselves with virtuous pedophiles. The pedophiles get to have consensual intercourse with children capable of giving informed consent, and people willing to get turned into a child and get molested by a pedophile in return for being younger get that.
I think the point of "normative dimension" was that the Forces Of Magic were working within a framework of poetic justice. "Problem solved" was IC.
There's a recent science fiction story that I can't recall the name of, in which the narrator is traveling somewhere via plane, and the security check includes a brain scan for deviance. The narrator is a pedophile. Everyone who sees the results of the scan is horrified--not that he's a pedophile, but that his particular brain abnormality is easily fixed, so that means he's chosen to remain a pedophile. He's closely monitored, so he'll never be able to act on those desires, but he keeps them anyway, because that's part of who he is.
What would you do in his place?
In the language of good old-fashioned AI, his pedophilia is a goal or a terminal value. "Fixing" him means changing or erasing that value. People here sometimes say that a rational agent should never change its terminal values. (If one goal is unobtainable, the agent will simply not pursue that goal.) Why, then, can we imagine the man being tempted to do so? Would it be a failure of rationality?
If the answer is that one terminal value can rationally set a goal to change another terminal value, then either
