Dunno about you, but when I was 19 the thought of raping a child never crossed my mind. He's spent less than a year in prison, and hasn't repented for what he did. Redemption has to at the very least come with an understanding that what he did was wrong.
Edit: slightly more than a year; 13 months
There's a pretty obvious difference between a kid who's 12, and someone you could reasonably mistake for being an adult (UK age of consent is 16).
