'I'm not a monster': So-called 'virtuous paedophiles' reveal inner struggle
They're the most reviled members of society - individuals with depraved desires towards children.
While the research varies, even by the lowest estimates, there are millions of paedophiles walking among us each day.
For many, just thinking about or acknowledging their existence is unbearable. But in a controversial call, some scientists now say we can no longer ignore the ugly truth of paedophilia, and that if we rethink the way we treat them, we have a better chance of stopping their criminal behaviour.
And in what will come as a shock to many, the latest research also suggests there is such a thing as a 'good' paedophile – people who harbour inappropriate thoughts about children but don't act on their sexual urges.
On 60 Minutes, reporter Liam Bartlett investigated the uncomfortable concept of 'good paedophiles'.
Admitting the notion of a non-offending paedophile is difficult to believe, Bartlett sought explanation from a Melbourne man who identifies as a 'virtuous paedophile'.
'Kira' as he's known online, says 'virtuous paedophiles' are attracted to children but have vowed to never act on their urges. He and his peers claim to have no control over their feelings for children, living a life in shame as they try to avoid temptation.
"We do know the difference between right and wrong," he told Bartlett.
Kira told 60 Minutes he first became aware he had different thoughts to other people when he was a teenager.
"At about 15 I was going through school. I was looking at boys, I was finding them sexually attractive," he said.
"But as I was growing older I wasn't attracted to boys my own age. Post puberty, I was more attracted to younger ones."
Pressed by Bartlett to reveal the age of boys he was attracted to, Kira made a startling admission, "In a purely physical sense, I would say seven, eight years old."
Kira knows what he feels is wrong, and he is adamant he will never act on his feelings.
"You associate [paedophilia] with monsters. It's very hard then to realise that, hang on a minute, I'm not a monster. I've got a morality. I could never bring myself to do something like that. But then, you've got this dark secret inside you, as well."
Todd Nickerson is another man who says he's a 'virtuous paedophile'. Speaking from Tennessee, he told 60 Minutes he was speaking publicly to try to educate the community about the difficulties he faces, and to assure people he wasn't a threat.
"I feel a great burden has been lifted off of me because now people take me at face value, they know what I'm about for better or worse," he said.
Todd, Kira and thousands of other virtuous paedophiles say they need greater understanding and more support from the community so they can continue to receive the help they require to remain law abiding members of society.
