Someone advocated having a Norwegian-style rehabilitative penal system in the U.S and I responded saying it's not as easy as that and there may be cultural or even biological explanations for Norway's successful penal system, outside of the system as a whole. That snowballed into a discussion of biological and social influences on crime.
That said, I'd be extremely surprised if there isn't a cluster of genes that is overrepresented in paedophiles - at the point at which we have universal genetic screening it might be possible to flag them for early psychological intervention - similarly to how people with a family history of glaucoma get more frequent eye checks.
Some cultures are more encouraging of paedophilia than others too - efforts to stop child sex abuse could probably get a higher cost/benefit ratio if they focused some effort specifically on those cultures - In the U.K for instance there have been the Rotherham, Rochdale, Derby, Nottingham and Leicester cases.
Basically the assertion that "all groups of people naturally have similar levels of propensity for crime and vice" is wrong and making that assumption hamstrings efforts to actually address problems.
