My dad killed himself when I was 17. He was depressed and on a whole crap load of meds. Now that I'm older, and know the TTATT, I suspect he realized it was all a sham and couldn't take it. He was already mentally unstable, and I think he just went over the edge. He was an elder and very zealous when I was very young, but some of the things when I was a teenager raised my eyebrows. I just think he couldn't take it, and knew he ruined our lives, and didn't want to go through the pain of watching us shit on by other elders and JWs.
I guess I'm a little different - I know the TTATT, but also love many things in this world and would NEVER commit suicide, no matter what. That, and I don't have kids, so didn't have to see them lied to and controled their whole life. Kids do make a little harder, I believe. Even so, I still couldn't do the big S.
