I was thinking about cognitive therapy to decrease the likelihood they would harm people as a result of the proclivities they cannot change. Some people have a natural urge to murder people all the time, if they learn to control it there is no reason they cannot contribute to society.
There's a program in Germany related to this, called Kein Täter Werden (to not become an abuser / don't become an absuer). I think it's controversial because the therapy is confidential, even if the participants have committed abuse.
