It can be both. It can serve as a way to ensure there is no enrichment of the priests family but it can also attract deviants. In fact even if priests were allowed to marry there would be just as many predators in the church because it's high trust career that let's you get close to children. There are actually more pedos in childcare and teaching then there are in the church so the whole 'evil pedo priest' thing gets a bit old. The pedo priest thing was kept in the headlines of the jew controlled news a LOT longer then other types of child abuses cases that's for sure.

In fact the reason we have pedo catholics is because it was an attack on the church. These people were specifically placed in the church by communists as an attack on western institutions. This is well documented.
