I think it's important for anyone who has been involved with the WT to understand how cults work and how they have been affected by them. People who have been in cults and not fully healed from that experience are vulnerable to being sucked into another.
Steve Hassan's book, "Combatting Cult Mind Control" is very helpful in this regard.
Scientology hurts people, just like the WT does, and uses many of the same mind control techniques.
