I've moved this over to this thread, because I think we are crossing over topics.
Although I don't for one minute think my 'suspect' is the only person capable of having done this (sadly there are probably many more), he appears to have all the attributes necessary.
I've contacted someone who knows him fairly well and thought you might be interested in what he told me in answer to my question of whether he would have known right from wrong, given that he had a drug habit and lacked control/authority in any form. This is the answer, without the obvious references that would identify him.
"The ethical landscape of Xxxxxxxxx is complex--and it was particularly
complex during the xxxxxxxxx. But, I think there were clear lines of
what is acceptable vs. what is unacceptable behavior. A lot of
xxxxxxxxx engaged in deliberately "unacceptable" behavior--killing,
raping, torturing, dismembering--to enhance their own status.
It was the fact that these sorts of things were unacceptable
that gave these acts power. That power came from the ability to defy
laws, customs and the social order, but it always relied on a strong,
opposing notion of what is right."
So sometimes politics and these sorts of acts are not so far removed after all.
