We’re getting pretty far afield, but I’ll try to reply briefly. Almost all of the sex offenders whom I knew were abused themselves, even the girls arrested for prostitution or other sex crimes. Yes, it is hard to change behavior that was ingrained in childhood.
If you ask a probation officer, sex offenders are the easiest to deal with. They are used to leading double lives and are masters of deception and manipulation. That is how they find their victims and hide their crimes for many years. Yes, many of them are religious, but the “religious self” is the face they present to the public. So, as it turns out, hiding behind Jesus-speak and God-talk is quite an effective means of disguising one’s true identity.
