Val, I dont accept lonliness as an excuse for what he did. There is no excuse for it, which is why he deserves the punishment and probably should do some time in my opinion.
But it seems to me like he was severly depressed, sexually repressed, rejected by a girl he really liked, and add that he was a brainwashed jw. Then he got totally wasted to the point where they had to let him crash at their house. That was his first mistake because he probably shouldnt have been drinking when he was in a mentally stressed state of mind. The second mistake was them putting him up in a room with a kid.
Had he not run into those jw's at the bar I dont think he would have been on the prowl for a child to replace his heartbreak over the rejection of the girl. I dont think hes your average child molestor on the prowl. You are right he should have left them and done something like go to a strip bar or pick up a chick at the bar or something like that but maybe that is how normal guys deal with rejection and depression not how a mentally screwed up jw does. The kid happened to be in the wrong place at the time when all this guys internalized, repressed feelings busted out beyond his control.
I honestly think one of the cruelest things the jw's (and other religions) teach is that healthy adults should deny themselves sexual satisfaction. Its mentally unhealthy and causes all kinds of problems.
When I say I feel sorry for him, its not to the point that I feel sorry for the victim of something like this. I also felt sorry for the cult woman who allowed her child to starve to death because she was brainwashed. I guess I'm just wierd like that.
