Well yes I know that, but seriously how many pedophiles are not child molesters? Pedophilia is considered to be mental disorder, it is on the short list of paraphilias.
The vast majority of sexual assault of a child, is from someone they know. Put a pedophile in that situation and most likely to some degree they will act on it. And considering that there is evidence of brain dysfunction, you cannot guarantee that pedophiles wont commit a sexual crime against a child. Every pedophile is a danger to a child.

Structural brain abnormalities in the frontostriatal systemand cerebellum in pedophilia
Even though previous neuro psychological studies and clinical case reports have suggested an association between pedophilia and frontocortical dysfunction, our knowledge about the neuro biological mechanisms underlying pedophilia is still fragmentary. Specifically,the brain morphology of such disorders has not yet been investigated using MR imaging techniques.Whole brain structural T1-weighted MR images from 18 pedophile patients (9 attracted to males, 9 attracted to females) and 24 healthy age-matched control subjects (12 hetero- and 12 homosexual) from a comparable socioeconomic stratum were processed by using optimized automated voxel-based morphometry within multiple linear regression analyses.Compared to the homosexual and heterosexual control subjects, pedophiles showed decreased gray matter volume in the ventral stri-atum (also extending into the nucl. accumbens), the orbitofrontal cortex and the cerebellum.These observations further indicate an association between frontostriatal morphometric abnormalities and pedophilia. In this respect these findings may support the hypothesis that there is a shared etiopathological mechanism in all obsessive–compulsive spectrum disorders."
