'you can't assume that every child victim will abuse children in turn and so their experience does not excuse their behaviour.'
The past is why the present is the present, no sexual abuse as a child no sexual abuse of children when that person is an adult, normally. You do not get a 2nd invitation to Orgy Island and the rewards that goes with it once you are back on the mainland. That is what Cuba's destiny was before they revolted so at least one side was reluctant to abuse that was 'one sided'. The victims taken ti the island are killed, as a move that was planned from the very first move.
There are 3 part to the whole story and to keep it simple I will use the RCC as their shepherd/flock relationship as it is quite close to parent/child one. When abuse happens in the home today to a low level family the whole unit is blown apart and the people devastated for the rest of their lives. The rich are never subject to any of that and both parties are considered 'special' and they rise in power in society and if they balk they are rejected.
Why would you come up with an effective treatment when lifelong misery is used to keep the abused 'in-line'?
Incest in it's 'normal form' is between a sexually aroused child and one of their natural parents. Let's go with that both enjoyed it and the other parent was 'aware', if not part of the it. Nobody is charged and all enjoy a prosperous life, . . . sort of. . . .
Target abuse would be something the Clergy would use and the 'abuse' is well planned out starting with the local Priest spotting a child with traits that can be harvested by the Clergy. A docile flock is desired rather than one that is well informed and vocal. Sending a 'certain Priest' with 'special skills' would be about as 'planned' as it could get. There is no admission that anything happened so the person from the flock is mocked and rejected by the clergy and most of the flock.
