Ummmm with respect, and I men it, I suggest that you look up Ratzingers "influence" in the cover up going back 30 years. Fry alludes to it in his talk when he says that Ratzinger threatened excumunication to people who spoke to the police.
Saying it went back further isn't a defence, its a condemnation of all who went before him.
No he never killed a child but what he did do, was insure that the misery and suffering of hundreds(1,000's?) of children was either covered up or was allowed to continue.
If he was not who is, but say the head of a social services department, you would spit on him.
