I was involed with 5 or 6 in my 7 years as an elder. I was a dyed in the wool true believer. I had a hand in disfellowshipping 4 people. 2 went back. I will be calling all 4 in the next couple of weeks to apologize. Not that it would make up for what I was involved with, but its the least I can do.
Once I started doing research I never went back. I couldn't even attend a funeral. I went before the propaganda session to give my condolences to the family and left.
