I think this gives us the first real look into the inner workings of this man's psyche. My guess is that some of the outer layers of his bizarre "reasoning" about "society's role" comes from exposure over the years, and especially on the internet, to the sort of "philosophy", "justification"...or whatever we should call it-- that is out there from numerous "pediophile support groups " (for lack of a better term)--we have seen some examples at links members here have posted recently. But the underlayer--that is a different story, I think. Really heart-wrenching, to think of a child and then a young man struggling with those kinds of inner yearnings, with those underlying experiences (if they are reported accurately) and feelings, trying to live with them and make some sense of them somehow, without becoming like what hurt him.
Unfortunately, what it doesn't tell us is how much he has succumbed to his urges (other than in his mind)...and certainly doesn't tell us, I think, whether he did have something to do with JBR's death--or has just chosen her super-high-profile case to jump into the spotlight of to make his "point."
Sad, sad...on all sides.
