Very good Frankn! The reason for this behaviour is: Loss of Love for neighbors.
Neighbors being defined as, anyone who has lived, is living, or will live.
A very smart man, back in the 1950's and 60's or so, by the name of Dan MacDougald, after having studied POW's during the Korean war, wondered what and why it was, of the 3000 American POW's, the majority of them either went insane, took their own lives, and/or returned home very very damaged by their experiences. While the same Turkish POW's, who only numbered around 300, were basically unaffected.
Mr. Macdougald was then hired in Georgia, to determine for the land and water beureas, as to why one man upstream controlling a dam and spillway, would release waters, and flood their neighbors downstream. Were they just doing their job?
The conclusion of his work was; loss of love for neighbors.
This man, along with his best friend, Norman Malick-Yonan, brought back from Turkey the Yonan Codex. The put together a course, to rehabilitate the most hardened of criminals, and started their first workshops in Reidsville prison.
When one has loss of love for theirselves and/or their neighbors, you will see fear and anger come to surface and the worst of atrocities committed. Even JUSTIFIED! Much as we all see these things still, even today!
I am very honored to hold in my possesion, some of the files, life bio's, and courses, of these men, who were ahead of their time. They would have done much good in the world, except for the fact, that reducing recidivism and making whole, even the hardest of criminals, did not put money in the courts/sheriff/wardens/prisons pockets. And as with most businesses: affect their pocketbooks and they will take you out. Shame, shame, shame.
The fact was true thousands of years ago, 50 years ago, and still today. Loss of love for self and for your neighbors, is the undoing of our humanity. Imho.
