Having lived in the era of file sharing programs not being monitored 24-7 against ~unlawful~ material, I have gained a strong tendence to treat pedophiles as less than human beings. I don't think I need to go into details about this, either.
Having also tracked the efforts of groups like Perverted Justice and Evil Unveiled, which have exposed several online discussion boards made by pedophiles FOR pedophiles, where they discuss their "activities", one can see that they come from all layers of society and all kinds of backgrounds, and there's one very clear trend that spans every single one of those communities: they feel like they're victims, in fact, they actively enforce that feeling upon anyone who joins up those boards.
The majority of them think they're only expressing their love for the children they prey upon, and that the children consent to it and enjoy it, even though that, by observing their own fucked up stories (which they make sure to share, mind you), they often go from one child to another, after they get tired of the original, and end up teaching the original child how to lure and abuse others. The worst criminal isn't one that does something bad and is conscious of that fact, its the guy who thinks he's doing good while doing terrible things.
These are people who destroy children's lives to satisfy their fucked up tastes and then do every psychological acobratic feats to justify their actions and think of themselves as victims. Sure, there are observable exceptions (pedophiles who know they're doing terrible things but can't help it), but they're quite a small minority.
And sure, by listening to them, we could maybe find a way to treat them, but before that happens I want these people to be tracked 24-7, and to stay as far as possible from anyone within their desired victim age range, and I want society to be aware of what they are, what they do and how far they're willing to go to get what they want.
