No.OK, then your answer to my question is that you think it is better for society if he can talk to no one.
I think it more likely that a perp confesses in the hope that someone else will take responsibility for the situation and do the right thing. The "right thing" being the involvement of psychiatric help and the judiciary and all the other people who are trained to get results.
I doubt that any significant number of abusers would confess if they didn't want help far beyond the abilities of a generic clergyman.
And if the confession is that of the victim, there isn't the tiniest shred of doubt that the only right thing to do is take them directly to the authorities and insist that they tell the truth.
