Could there be any connection between the prideful superiority of the Catholic church and its Pope and the serious problem with pedophile priests? Sandusky had the same kind of superior pridefulness and inability to even realize that he was wrong. Any institution which has an overwhelmingly inflated opinion of its own perfection stands in danger of serious mistakes, even a great University. The Greeks call it HUBRIS.
The problem among priests was not pedophilia, but ephebophila (look it up). All religious groups have people and even leaders (i.e. pastors, etc.) who are exposed as pedophiles or ephebophiles.
