I have mixed feeling about the OP. Yes, we are all responsible for the decisions we make, but the Watchtower lies about their history and practices. They use their understanding of human behavior to manipulate and control their members. Are victims responsible for being victimized? Maybe, to an extent, but the majority of the responsibility lies with the Watchtower.
I look back at my time as a JW and, probably like all of us, wonder what I could have done differently to prevent wasting thirty years in a soul sucking cult.
I was thirteen when my parents and I started a bible study, I was much influenced by my much older sister, who I adored, and who became a JW before me. I loved the idea of a paradise earth, I was naive and took many things at face value. The Watchtower seemed to have all the answers in a troubled world. I researched at the library, but little information was there (obviously pre internet) that might have helped me, and of course I was told not to listen to "bitter apostates".
From that point its just like anyone else, meetings reinforce your beliefs, you have no reason to question things, you get busy with raising a family and making a living. It was not until my forties that I started learning critical thinking skills, and also had some difficult circumstances that caused me to start to question things. Once I did, I quickly lost my faith, I walked away and didn't look back, I didn't even find JWN or other JW critical sites, I just knew that the Watchtower wasn't what they claimed.
So, did I deserve what I got? I don't know, maybe to a certain extent. But I feel the majority of the blame goes to the leaders of this religion, that lied, that hid their history, that used mind control techniques to keep people ignorant and enslaved.
