Any religion into which people are born and raised without choice, (as opposing to knowingly choosing membership on an informed basis at a responsible age) is pretty much bound to encompass both the best and worst ends of humanity and everything inbetween, as there is no selection process. One glance at the history of Catholicism and that is horribly obvious; the bigger the religion, the more obvious those extremes are. Whatever brand of dogma people happen to be raised on, they will ultimately process and interpret it to suit themselves, albeit within the confines of their surroundings. I personally think that Catholicism (the monolith as seen from outside) couldn't care less who it has as a member as long as it maintains its economic growth, stability, power structure and expansion. I don't think it sets out to produce either good or bad people, just people who aren't non-Catholics. It started as a political movement seeking power and wealth, and (when viewed from the outside) it still is. Their power structure provides equal opportunities for both 'saints' and child molesters, and as Joe says it's impossible to tell them apart, save by their actions, and even then it can be debatable. Catholicism should start caring for people instead of just regarding them as a means to an end if it wants to maintain any credibility in a world that is slowly but surely waking up to reality. Or at least a broad band of mutually acceptable reality anyway. We yet have a fair way to go..

Child molesters almost invariably don't give it up unless they are physically forced to - Chris is right; they would still be doing it if they could get away with it, no question about it. It's not a disease and there isn't a cure.
