Congregations of Jehovah's Witnesses experience the same power struggles that companies, corporations and other secular entities go through. Individual JW's who simply "wait on Jehovah" can get crushed. Entrenched elders can be ruthless bastards without a hint of scruples or mercy. Sometimes the difference maker is the presence of an advocate, another elder, a circuit overseer, someone at Bethel who knows you well enough to realize that what is being said about you is a lie.
In about three decades as an elder, I survived several of these wars. The final one, involving my offspring, did me in.
In my experience, there is nothing one can do to nudge, influence or hasten someone's departure from JW's. They must reach that point individually.
One final blow for the sincere JW who is being smited by vindictive elders is the letter they send to the congregation the wounded one moves to. The wounded ones may find themselves never fully accepted because their "resume" contains inaccuracies impossible to live down.
