Actually, you did very well in terms of compassion. I thought I could feel the 'throw them in prison forever and let the other prisoners take care of them' thing coming up, but by the grace of God you forebore from that distinctively American cliche.

My friend whose dad sexually abused him (without adding the folly of photography) couldn't offer much insight into how his dad excused these actions to himself. His dad also cheated on his marriage with other women and was basically a 'successful' guy who was used to taking what he wanted. Some alcohol helped him to become a night-terror for his son. He eventually committed suicide after being discovered doing something with a friend's young son. No chance for an insightful autobiography.
