So your theory is that no matter how people organize themselves they will always commit mass atrocities? I can agree with this on some level, there is a lot of psychological disturbance among human beings and has been throughout history.

I'm wondering if you are aware that there is ample evidence in the work of Adorno and his collegues (http://en.wikipedia.org/wiki/Authoritarian_personality), Lloyd deMause and the Institute for Psychohistory (http://www.psychohistory.com/) and Alice Miller (http://www.alice-miller.com/index_en.php) that political and military disasters are not linked to something intrinsic and inevitable in human nature, but rather to childhood and even prenatal experiences that can be avoided?

If you haven't, you might take a look at Lloyd deMause's book "The Emotional Life of Nations" (readable online: http://www.geocities.com/kidhistory/childhod/chindex.htm), which I think traces this ability of humans to murder and pillage to it's source and provides a plan for how it can be eliminated in the future.
