I was at this point over a decade ago:
If "the truth" was a lie, then all the beliefs that I had developed would need to be thrown away. It would mean that God didn't
intervene in my life and give me a higher purpose. I wasn't serving Him by
peddling WATCH TOWER magazines. I only saw two options: blame God for taking me at my most vulnerable moment and leading me
into the Watch Tower organization, or remove God from the field and take blame for myself for being duped into the religion. I needed Him as my scapegoat.
But as time went on, I discovered so much more. Millions of people are duped. I don't need to wallow in self-blame. I made what seemed like an important life choice, a valid one at the time, and I was wrong because I was misled by a dangerous mind-control cult. My bitterness with God died and I remained bitter with the organization known as Watchtower. It does no good to self-blame. That's something that many abuse victims go through also, and it just isn't reality to self-blame.
I tend to agree with you that there is no Jehovah in all that, and my atheism is from a serious look at the evidence. But even without such solid evidence for a lack of God in things, I wouldn't serve God through religion now unless He personally proved himself to me.
I have taken years to find peace, to find a balance because i still have a wife in the JW's. It's a tough road, but there was never any possibility of turning back or remaining the the congregation as a silent nonbeliever.
