They are so accustomed to having someone tell them what to do in every situation that they do not want to have to make decisions for themselves. I'm not talking about a physical laziness, but a laziness of intellect.
Thank you for sharing some of your experience. I have to say that many people have different circumstances in which they leave (some fade and as such have time to prepare, while others are thrown out into the world outside by getting disfellowshipped). People also have different personalities, attitudes towards life outside, and capacity to discern things about the world around.
Also, people have different levels of attachment to that organization and their believes. Some are emotionally attached as they feel that being a JW is part of their culture, and others, like me, couldn't care less about anything JW after I left, as influenced by them as I was. Others leave but still believe in what they say to various degrees.
I embraced leaving, and was looking forward to my life outside. Yes, I did and still do have a little bit of the follower, but people are not robots, and people aren't stupid either. We found our way as we minimize the influence of that organization.
