Nope people just become pedo's because they can't get married, the pervs joined the church because it's easy for them to gain access to children. This was a big problem here in Ireland for years, since Éamon de Valera gave the catholic church the power to run our schools and look how that turned out. The church had it's tendrils in a lot of Irish life over the last century, from running schools, orphanages, industrial schools and Magdeline Laundries.
They're plenty of priests out there that don't go on to molest kids but if they stand by knowing about the abuse and do nothing by refusing going to the proper authorities, they are just as guilty. And up to recently and I mean recently within the last ten years or so it was church rules to keep the abuse covered up and to ship the abusers to South America and than ship them to another parish somewhere else. Hell even the local priest in my town threatened to sue a woman if she went around saying she was abused by another priest.
Below is a official document from the Vatican on what to do with perv priests

And a very disturbing documentary on the church and it's abuse cover up

And personally I think the church should allow the priests to marry, but the abusers will still join any way.
