There is a maxim of law that pisses off lots of people: The Church Must Survive. The structure of the church is the foundation for our legal structure, and even that of the United Nations. to collapse the Catholic Church would be to collapse everything that has been done under its authority (including all non-sharia governments of the world). Therefore, gutting the bad actors while trying to leave the structure of the building intact is best done by someone with a lot of work in the construction sector, like our current POTUS.
