He is very important person in my life and I know he's not a pedophile. Nor is he defending them. It is very rude of you to make that accusation.
In psychiatry pedophiles are those who have sexual fixations towards minors. And lot of them were sexually abused as children. They may or may not be acting on those tendencies or even expressing them. It's not treatable (currently), but manageable. Would you kill someone based on his mental illness instead of actions?
Also not all child sex offenders are pedophiles. Some of them do it for profit or another end.
