Please think about this before complaining. My thought is that the very paradigm that priest must be celibate selects for the abnormal person.
But first, a brief history of clerical celibacy:
http://www.futurechurch.org/fpm/history.htm______________________________________________________________________
306-Council of Elvira, Spain, decree #43: a priest who sleeps with his wife the night before Mass will lose his job.
325-Council of Nicea: decreed that after ordination a priest could not marry. Proclaimed the Nicene Creed.
352-Council of Laodicea: women are not to be ordained. This suggests that before this time there was ordination of women.
385-Pope Siricius left his wife in order to become pope. Decreed that priests may no longer sleep with their wives.
Fifth Century
401-St. Augustine wrote, “Nothing is so powerful in drawing the spirit of a man downwards as the caresses of a woman.”
Sixth Century
567-2nd Council of Tours: any cleric found in bed with his wife would be excommunicated for a year and reduced to the lay state.
580-Pope Pelagius II: his policy was not to bother married priests as long as they did not hand over church property to wives or children.
590-604-Pope Gregory “the Great” said that all sexual desire is sinful in itself (meaning that sexual desire is intrinsically evil?).
Ninth Century
836-Council of Aix-la-Chapelle openly admitted that abortions and infanticide took place in convents and monasteries to cover up activities of uncelibate clerics.
St. Ulrich, a holy bishop, argued from scripture and common sense that the only way to purify the church from the worst excesses of celibacy was to permit priests to marry.
Eleventh Century
1045-Pope Boniface IX dispensed himself from celibacy and resigned in order to marry.
1074-Pope Gregory VII said anyone to be ordained must first pledge celibacy: ‘priests
first escape from the clutches of their wives.’
1095-Pope Urban II had priests’ wives sold into slavery, children were abandoned.

In fact, as late as the fifteenth century half of the priests in the RCC were married and accepted by their congregations.
My point at the start was to argue that enforced celibacy selected for the very tendencies the we today find abhorrent.
Man (both the male and female varieties) is born with some innate, hard wired drives. After survival, the most forceful is procreation, the drive to pass on our genes. I would argue that celibacy is even more difficult because it negates another hardwired need: The need to be loved and accepted by another.
If this is true, and it is accepted psychology now, then anyone pledging celibacy for life is going against his basic needs as a human being. So it would follow naturally that for those in training for the priesthood, denied the contact of females, would turn to each other for contact. The problem comes when those in the priesthood, with the power of their position, turn to those innocents they are supposed to be shepherding and use them for substitutes.
This subset of what is called abnormal is present in all of society, but in the general population they don't have the cover of their position to hide behind. In a setting such as the church, they would be attracted to the facts that they would have power, cover, and plausible deniability. They would be powerfully attracted to the position, not to forge that in their early years they would feel apart from society and the priesthood would certainly satisfy that.
