My father (a violent alcoholic con artist and sociopath) was pretty damn depraved. And he was a faithful Jehovah's Witness.
I await the "he was never really a Witness" defensive countermove. But that would not work, because he was a major player in the Kingdom Hall while he was doing lots of bad stuff. As a con artist, he was a very persuasive member of the JW's and probably converted more people than anyone else in the congregation at the time. I watched him work his magic house-to-housing, using us kids as bait, and reeling in the old black ladies one by one with his gift of gab.
Thus from a young age I learned to identify BS when I heard it, and I also realized that con artistry, a charming personality, craziness, scary violence, hypocrisy and religious fervor could all co-exist quite nicely inside the same human being. With that background it should not come as a surprise that I eventually became an atheist. The surprise is that I stayed with the JW's as long as I did, and even tried to remain vaguely religious for a bit after leaving them.....
The other JW leaders knew about a lot of his wrongdoing-- they even came to the house and saw all the empty booze bottles, for example. My 6'3" father was beating my five foot tall mother regularly after coming back from bible study, house to housing and the Kingdom Hall. There were times he chased her out of the house barefoot into the snow. The JW leadership told my mother that her main problem was that since she did not participate in the JW activities with her husband, she was not as faithful a Witness as he was. So how could she expect any help from Jehovah God?
My father was finally excommunicated, but not for running cons, not for nearly killing his wife, and not for abusing his kids, and not for drinking up his paychecks and running the family business into the ground. He was not kicked out until years after we had all moved away from him. He began to challenge the Watchtower Society's interpretation of the bible, writing up his own versions of what prophecies meant.
That was it, he was kicked to the curb. Until his death, he maintained that he was right and the JW's were wrong. Clearly, he is not going to be in the earthly paradise of everlasting life....but he would have made it if he had not gone against the JW teachings. Well, that, and the forbidden blood transfusion that probably saved his life when he was in his 80's.
My brother stayed in the faith, dedicated his life to the JW's and became an elder or whatever the high mucky mucks are called. He learned to be a JW from our dad, so if dad "was not really a Witness", than neither was my brother. Or my sister-in-law, who joined because of my brother. And neither was anyone either of them converted.
You can "know them by their fruit", right?
