To speak of morals from an atheist perspective is a meaningless non-starter.
This isn't to say "atheists are BAD" or anything like that. It's just to say if atheism were true, there would simply be no such thing as "bad" to begin with. This is why the bad logic from the stereotypical "pimpley basement-dwelling limey with the Richard Dawkins poster" is so cringey when they try to use the scandals of the Vatican as an argument against religion.
If there were no God, then not only would the Vatican's pedophilia scandals not be wrong,
NOTHING would be wrong.
