It's my opinion that anyone, regardless of denomination, who allows outside human "interpretation" or blatant man-made rules to run their lives gets what they deserve. Not to remove all blame from people who run cults, governments, or churches, but it is our own brains we need to protect from being washed. Most people are so lazy and/or apathetic they'll give control of their very minds over to someone else. Human nature being what it is, if you offer your mind to someone else - especially someone who craves that very power - they'll take it.
The vast majority of people in churches - JWs included - claim to base their lives on the Bible, yet have never read it. Many of the ones who do read it don't care enough to pay attention and don't comprehend and/or immediately forget what they read. Repeatedly, the Bible warns against granting other people power over your faith, because they are imperfect - both in ability and in motive. (2 Thes 4:3-4, 1John 4:1, Acts 17:11, Pro 14:15, Eph 4:14-15, Gal 2:4-5, Col 3:23-24, 1Sam 12:20-21, 2Pet 2:18-21, 1Tim 4:1-5, Psa 146:3, 118:8, Jer 15:5, Luke 11:35) If people ignore all of those warnings - and many others, both direct and indirect - in favor of some convoluted, pathetic explanations of what "faithful and discreet slave" and "Be obedient to those who are taking the lead among you and be submissive" mean, then it's difficult to have too much sympathy.
This isn't 1100 AD, people. You can get a Bible for free, at a dollar store, read it online in many versions. The rich man and Lazarus was all about access to the Scriptures. For hundreds of years, people were willing to die to see what the Bible really said, so they wouldn't have to take their clergy's word for it. Now, people have one sitting on the coffee table they completely take for granted. Meanwhile, they claim to live by it. Then, they blame a denomination for the duality of their mind where they will entertain conflicting thoughts and brainwash themselves to hold both as truth.
People blame the Catholic Church for Inquisitions, Puritans for witch hunts, Nazis for the Holocaust, cults for mass suicides, governments for wars and war crimes, etc. Why are all the people who actually perpetrate the deeds absolved of responsibility? We invite mind control by not taking control of our own minds. JWs are just another group of people acting as a group. Mob mentality is a very powerful thing, but every mob is made up of individuals who have relinquished their minds to the mob and each is personally responsible - in courts and to God.
