Puffer, your story both hurts and helps to read. Those pictures....I look at them and wonder who on earth could look at that boy and want to hurt him? I think the same when I see a photo of myself as a boy. I guess the answer is, "a sick monster would."
I found a quotation in a reputable book about this*. It is talking about torture as used in interrogation. I think that what I endured was possibly explained in terms of perfecting techniques which could be applied to interrogation.
Victims often need extensive treatment to recover from injury far more crippling than mere physical pain. Perpetrators can suffer a dangerous expansion of ego, leading to escalating cruelty and lasting emotional disorders. Though any ordinary man or woman can be trained to torture, every gulag has a few masters who take to the task with sadistic flair -- abhorred by their victims and valued by their superiors.
I'm not sure whether the lasting emotional disorders referred to here are those of the perpetrator or the victim.
He goes on...
Applied under the pressure of actual field operations after 1963, psychological methods soon gave way to unimaginable cruelties, physical and sexual, by individual perpetrators whose improvisations, plumbing the human capacity for brutality, are often horrifying.
Why, one might ask, is psychological torture so devastating, inflicting harm that is often more lasting than even the most brutal form of physical abuse?
victims suffer "a mistrust bordering on paranoia, and a loss of interest that greatly surpasses anything observed in anxiety disorders."
The subject...remains a tired human being, relatively uninterested and unable to concentrate.
I don't think that in my case I demonstrate all of these symptoms. I went on to graduate from college and graduate school and a teaching career. It may be that I achieved this in spite of what happened. After I "remembered" what happened there, I really did lose focus. I've been like that for about 30 years. There was another major incident of abuse by those perpetrators. I haven't reported on it in any detail here. I'm still trying to figure it out.
