I believe a lot of the constraints of the JW cult have little to do with faith in God and more to do with strength of being born in a cult ie fear obligation guilt. So let's say you would naturally be an atheist if not born in, the social and emotional pressure of the cult makes you fight to believe even if you don't. "You just don't have enough faith".
Scientologists don't believe the desert god yet they are equally as screwed in a control system. And north Korea as well. Even when God is absent high control groups are doing what they do and replacing it with something else.
For me it was a big moment allowing myself to be atheist, I would say I turned, I was just constantly trying to force myself to be a theist.
