Often for both the pedophiles and society.
"Makes you wonder what the cause of the desires is, like I can't think of a good biological reason why men wld be attracted to kids"
This was based off some fMRI or MRI scans that found that the areas of the brain that were activated during sexual stimulation also lit up for pedophiles when they seen pictures of kids. The attraction seems hard-wired, but that doesn't make them necessarily innate. Pedophilia is just one among many paraphilias. I'd bet if you stuck a necrophiliac in an fMRI machine and showed him pictures of some newly-deceased body, their scans would also show the same brain areas light up as when a heterosexual man sees an attractive woman. I could probably do some digging on the general topic, but I feel like it's common sense?
It looks more like both pedophilia and necrophilia have psychological components that play on innate biology. Like you said, there doesn't seem to be a good biological explanation—at least a purely biological one at any rate.
"Now, many experts view it as a sexual orientation as immutable as heterosexuality or homosexuality. It is a deep-rooted predisposition — limited almost entirely to men — that becomes clear during puberty and does not change."
This makes me feel a bit sorry for paedos, not the shitheads who act on their desires but the ones who have the feelings and don't want to. Makes you wonder what the cause of the desires is, like I can't think of a good biological reason why men wld be attracted to kids
i've heard in Germany they treat it with chemical castration and have quite good success, I'd be all in favour of doing that.
