I am curious about how you differentiate those who were "good" to their "newcomers" from those who were bad. Isn't it only a matter of degree? Do you draw the line at physical abuse? But isn't it physical abuse just to keep somebody your prisoner?
Maybe some of those people you are looking for have come to regret their actions and see themselves as having been under the influence of a cult.
I can't argue with your anger, and won't. There have been times when I was that angry. Maybe I am just repressed right now. I did post that thing to Brady Minnick. Thinking about what he did upsets me -- if he had not told me that lie I would not have given up trying to get out of Straight. That lie changed everything. But maybe he has come to realize the awful part he played there, in which case I can't see holding a grudge against him now.
I also can't see holding a grudge against anyone I was in there with. They were just innocent teenagers like myself, caught up in a bad thing. It does get confusing, because if I think about things from Straight it hurts. But in terms of being mad at those people to this day -- why would I? Either they have come out of the spell they were under to make them act like that, and regret their actions and words, or they haven't, which is really sadder.
In Straight I didn't have a newcomer for that long, but I did become quite militaristic. I was always poking people to get them to sit up. If you remember that, you might feel rage at being helpless in a blue chair with someone poking you. But it wouldn't make any sense to come after me now, you would just be attacking some part of me that has mostly disappeared and that I wish would entirely disappear.
