As in, What really caused Pope Benedict XVI to resign?
These priests, bishops and cardinals need to be either de-frocked, or if Canon Law doesn't permit that, reassigned to monasteries to live as hermits for the rest of their natural lives, never to be allowed the privilege of ministering to the public ever again. The Church certainly has enough half-empty monasteries to hold all the offenders.
And no more gay priests, IMO. Much of what is called "pedophilia" in regard to the scandals in the church is nothing but old-fashioned pederasty: grown men diddling pubescent male youths. Make homosexuality a disqualifying trait for the priesthood and you'll clean up nearly all of the problem. Sorry if you don't like that, gay men.
