I wonder how many of these predators are getting off as much on the virtual corruption of some negligent parent's innocent offspring as they are a sexual attraction children.
If the perps are sociopathic/psychopathic/etc. we can definitely expect that to be a major factor. Sociopaths look for weak, vulnerable people that they can easily manipulate and exert some sort of power on, and kids fit that description quite closely. "Sexual attraction" in its everyday sense would be quite secondary.
