I believe this as the truth though. What he is saying is perverts will be perverts, they can't change and those who are true pedophiles don't WANT to change. Stopping them from wanting to have sex with children is like trying to stop you or I from not getting turned on when a beautiful woman (or man) is coming on to you, it just isn't going to happen.
Now that they admit this then they have to admit that you can't cure it either, a pervert will be a pervert in his head no matter how you try to "reform" them. It will be up to them to abstain if they have the opportunity to rape a child because they admit here it can't be counseled out. It will all come down to having to trust them to "do the right thing", which will never work.
A sociopath is no different, and we lock them up forever for societies sake, his admission to this should amount to the same view towards perverts, either lock them up or make it impossible for them to act out their fantasies.
We may agree that pedophiles are very difficult to "cure", but the fact remains that this is all part of a plan to convince the public that pedophiles are not accountable for their actions, and that is very, very dangerous.
