A lot of what I see as pedophilia is a mix-up of the natural aesthetically appealing (cute) nature of children with the sexual appeal of post-puberty adults. They are not the same thing, but some people are unable to distinguish the two. It doesn't help that society has increasingly sexualized children and their attire, either. People, these are kids, don't dress them up to look like sluts. Furthermore, the desire to want to investigate and be close to a child is fairly normal and I believe a construct of evolution. Evolutionary pressure would state that children with best ability to draw an adults attention would survive to adulthood. Normally, a child in the attention of an adult is less likely to suffer harm or die.
The question remains to be a method to either replace or correct this wrongful cross-link of cute-appeal and sexual appeal. I know many males are typically poor at understanding and analyzing their emotions, usually categorizing huge masses of emotions along the lines of happy, angry, sad, etc. So emotional literacy on the part of a pedophile might allow him or her to understand that this general attraction towards kids is not sexual, nor is it entirely unnatural.
