:: He goes into therapy and begins deal with being raped at 8 by three teenage boys in a "Church School" growing up and continues to be molested though his teens. Begins to understand and piece together what the abuse is doing to his life and where all the fears and anxieties are coming from. He also realizes that he has followed in the steps of his abusers and has also vicitimized others. He goes to the elders AND families in the congregation realizing the need of change and asking for help in doing so. He's not 'reported' by the elders he confides in, but is severely reprooved.
MANY MANY IF's here. One you seemed to miss...
*IF* the boy had told on the boys who raped them, and saw JUSTICE administered as those three boys PAID FOR THEIR CRIME. The victimized boy probably would have never... EVER... molested anyone else and put them under the same pain that he went through.
Now, *IF* he told the authorities within the church and they COVERED IT UP instead of letting him CONFRONT his abusers, AND let the molestation CONTINUE, then you can see just why he became a molester himself. It was the only way he could reconcile the injustice done to him. Does it explain it? Possibly. Does it EXCUSE it? Definately NOT. Could it have been avoided. QUITE PROBABLY!
Your problem is you are sympathising and analyzing the ABUSER after it is TOO LATE. If you concentrate on the VICTIM's recovery, then you will most likely stop the victim from becoming the ABUSER later on in life.
