I would say he was where I was about ten years ago. Having doubts about the org. and just about ready to resign as an elder but believing the "new testament" as a Christian and foolishly thinking (me not your father who sounds great) I might be instrumental in trying to protect the flock while remaining an elder.
The point about child abuse strikes a chord. I went to the Police and asked for and got their assurance of keeping my identity anonymous without telling the rest of the body about a child abuse case. (I also told the police I would stand up in court if they needed my testimony but in the end they got their information from a first hand source).
I also hated those money meetings at the circuit assembly but was dumb enough to question the proposals in public.
Sorry, this sound like it's all about me. I just think your Dad was awakening or awake and a really good elder to go to privately for any jw.
The nice thing is he probably died with his faith in Christ and a resurrection - to heaven or earth - largely intact.
