I think the emphasis on celibacy as a contributing factor in these cases is misguided, for a number of reasons.

Lots of people live celibate lives, some by choice or religious vow (and not only Catholic clergy), and others not.
We don’t expect celibacy to be an excuse or justification, or a mitigating circumstance, for rape or molestation in those cases, and neither is it here.

That being said, one of the problems that has led to this crisis in the Church has been the celibacy requirement— specifically, the difficulty of attracting men to the priesthood and the gigantic drop off in numbers of clergy, starting in the 60’s. Fewer applicants increases the likelihood of letting bad applicants in.

But even so, the real problem here (apart from the endemic coverup and culture of silence within the Church admin), is and has always been the Catholic Church’s attitude toward sexuality in general and female sexuality in particular. It’s a culture of shame. Women and sexual desire are treated as lesser and other, consequently some of the men steeped in that culture (like priests) act as they do.
Individual Catholics may disagree with me here, saying that they don’t have those feelings about women or sexuality, or that their friends and family don’t, or even that they know individual clergy who don’t. I’m not disputing that at all— but my point remains.

Bear in mind here that the official position of the Catholic church IS that sex is only for procreation— that is one reason for the prohibition on birth control. Many Protestant denominations regard sexuality between a man and a wife as one of God’s gifts, meant to bring the couple even closer together. While some individual Catholic parishes will say this, and this is the sort of thing that many Catholic couples going to pre-Cana are taught— it isn’t standard and it is contradicted by the Church’s official positions on birth control.

That is one of the features of Catholicism that I think would need to be drastically changed, as well as the other institutional problems— the general attitudes towards women and sexuality. Accordingly, the problem runs a lot deeper than the individuals involved in the coverups, and unfortunately I don’t see the kind of drastic change that would be required happening easily or soon.
