The message I got was that church dogma, whatever it may be, gives its clergy the impression they have permission to use others as sexual objects because they always have the opportunity to absolve themselves of such transgressions through acts of contrition. So, "the victim be damned because I can always put myself right with the lord, and that's all that counts." Through the doctrines and principles of the Church children can be considered the sexual toys of abusive priests
Latin rite clergy are obliged to live in continence (which means no sexual activity whatsoever). Unfortunately, due to a long neglect of traditional disciplines specifically designed to weed out men not capable of such a commitment the seminaries admitted untold numbers of candidates who should never have been allowed anywhere near the priesthood to begin with. For example, the rules had long stipulated that obvious homosexual tendencies constituted immediate disqualification for a priestly vocation. And this was obviously ignored to the point of criminality. (It is not a coincidence that the majority of victims were adolescent boys). The rules (at least traditionally) also stipulated the priests who committed serious sexual sins were to be immediately deprived of their clerical state. Again, this was utterly ignored for decades.
The problem wasn't Catholicism. The problem was an attitude in vogue during the mid twentieth century which in the name of 'mercy' watered down Catholicism and perpetuated the misguided idea that you could reform serial pederasts. The problem were bishops who for one reason or another were just too unwilling, too cowardly or too lazy to deal with the problem in any substantive way.
Confession isn't a blank cheque to do what you like. (That's an idiotic strawman). A valid confession requires the serious commitment to reform and not commit the same sins again. If a person is confessing pederasty every second week then he is obviously not contrite enough to receive absolution. Indeed, committing sins with the intention of confessing them later is in and of itself a sin.
Priests don't commit sexual abuse because of their Catholicism, they do it despite it. And the bishops who ignored it for decades did not do so because of their Catholicism, but despite it too concerned with their careers and not stirring the pot than doing what they were actually to ordained to do. Guard and teach the Catholic faith and to work for the spiritual good of their flocks. (Which includes taking action against scoundrel priests).
