That would be solving the problem at the source.....thus preventing the infection in the first place. That's a concept most here do not understand. Thing is, then Cardinal Ratzinger back in the 90's has already done exactly that, which is why the incidents  of actual abuse have sharply declined to near zero in modern times. All that the Church's detractors have to go on is their own hyperbolized inferences and their own misguided desires to castigate a sitting bishop, cardinal, or pope.
