Moral superiority to religion and the religious is at the very heart of New atheism and antitheism.
I think it's been established that being an atheist doesn't prevent you from being a bad man. However, what is at issue is what the organisations that these bad men are part of do about it.
One option is to be transparent about it: have an investigation, take action to dissociate the organisation from the person,, turn the evidence over to the police if they have done something potentially illegal.
Another option is to quietly relocate the bad man, bribe or threaten the victims, maintain a wall of silence with respect to the legal authorities.
Guess which of the two options the Roman Catholic Church took? Moral authority, my arse.
