Responsibility isn't some kind of moral yard-stick, it's a matter of cause and effect. Holding someone responsible for their actions is an entirely different matter from deciding what to *do* about their actions.

In the cases of the sexually abused young males you have worked with, whose understanding of reality and good and evil have been warped and they continue the abusive pattern at the expense of innocent individuals, I would argue that there is a *collective* responsiblity, both on the part of the original abuser and the abused and subsequently abusing victim. For the abuse to continue, *both* individuals have to enable it.

"Who's responsible" is the easy part, it's deciding what to do next that's hard.
