I've actually been wondering for the last few years if pedos specifically go to the Catholic church to become priests as a way to try and control their urges, the sexual desires that they know are wrong, to stop themselves from harming children?
Clearly that's not the /end/ result, but I've often wondered if that was their original intention.
It doesn't help that the culture of the church is one of "forgiveness", and the idea they foster that, apart from a few mortal sins, no matter what you do, if you truly repent, you will be forgiven and reach heaven.
