Except the proportion of paedophile priests is about the same as the proportion of paedophiles in the general population. There are more paedophiles in schools and social services than in religious organisations - and there have even been more convictions of teachers and social workers, at least tin the UK. The reason you think of the Catholic Church this way is BECAUSE it got more media attention earlier than elsewhere. A surprising number of people the UK do not know about the biggest big paedophile scandal in the country, the Islington one, that was huge, and at least one politician who was responsible for the failure to investigate went on to have a successful career in politics (the only time it set back her career at all was when Blair wanted to make her minister for children there was a backlash)
I doubt you have any reliable statistics about this, given how many victims keep silent out of fear.
But in any case, the moral failure of the church was not the existence of individual abusers (which indeed can exist anywhere in society), but how on an institutional level known abusers were protected by the curch. Everyone who was part of the cover-up (which went all the way to the top) is complicit.
