First, I think there is a need in them that, once innocent, was not fulfilled (being loved as a child perhaps?)... now I don't know if their anger against their mom has anything to do with, and the way they later lash out at women... and I'm working on memory here not research statistics.. but whatever basis they have to begin with, society allowing the visual perversion to continue without hardly any barriers... they live in a world other than reality??? They know nothing else...or at least it doesn't give them any sensation?

In short, they become sick, truly mentally unwell, needing to seek and find this perversion. Not all who are abused (neglected) as children fail to thrive in a normal way... but there are plenty who don't imo.
