BONAFIDE- This happens all the time. I remember a regular pioneer sister who was an absolute $itch . She intimidated any other sisters or brothers reaching out to auxillary pioneer or regular pioneer. She would only work with one or two close friends and would not include others in her service group. I'm a big believer in Karma- last I heard she cheated on her elder husband with a wealthy 83 year old witness to try to scam her elder hubby out of their house. She got DFed and is trying to get back in I hear. She was diagnosed as Bi-polar with depression.
Another elders wife in the early 1980's intimidated people in the congregation where people ran in terror of her. There was emotional and physical violence and abuse going on in her and elder hubbies home towards the 17 year old daughter- but they tried to hide it from other elders. In time it was exposed , the husband got deleted as an elder and he and the psycho wife got pissed and moved to another congregation where they could be emotional terrorists ! Once again Karma bit them in the behind
