The problem with abuse in the Catholic church stems from two distinct aspects of its methods -
The first is that it continues to encourage its priests to live unnatural lives. Their celibacy and denial of the comfort of a normal family sets them apart from the very people they are supposed to help and support. If you are going to help and support families, it does help if you have some experience of family life yourself.
The biggest issue however concerning priests is the poisonous attitude of superiority and entitlement that is delivered to them from Day One of their priest hood.
They are surrounded by people who adore them, and hang on their every word, and believe that they can never do or say anything wrong. That level of adoration is catnip to the perverts and abusers that the church attracts, men who believe that they are entitled to abuse people, especially vulnerable children, and they are encouraged and protected in that belief by a church which revels in its secrecy and its willingness to simply relocate discovered priests so they can abuse elsewhere.
There is no sign of either of those concepts being altered any time soon, since in order to be in a position where you can actually influence change, you already have to have proved that you endorse the systems as they are.
It's a self-perpetuating secret and protectionist system that will never change.
Priests are arrested adolescents, they lack emotional maturity and interaction, and they fill their time receiving undeserved adoration, and plotting their macheavlein schemes to protect and preserve what serves them so well.
