Dennis, you are correct, much more to the problem.  I have a question for all who read this comment, how can it be possible for a human being or an organization that has heard countless stories from victims of clergy abuse as children, they have heard the tragic consequences like destroyed childhoods, not being believed, carrying lifelong shame and pain, the destruction of families, daily partial suicide either by substance abuse, severe depression or just hopelessness that many times leads to ending ones own life. 
Most victims were hurt even worse by the callous response to their pleas for help from bishops. So often the children were knowingly put in harms way by bishops who knew a priest was an offender.  Most children became victims because of their desire to become closer to Jesus by serving mass or getting more involved with the church.   

Why was knowing about all of the pain caused to Catholic children not enough of a catalyst for this church to change on its own?
