During World War II, Nazi doctors had unfettered access to human beings they could use in medical experiments in any way they chose. In one way, these experiments were just another form of mass torture and murder so our moral judgement of them is clear.
But they also pose an uncomfortable moral challenge: what if some of the medical experiments yielded scientifically sound data that could be put to good use? Would it be justifiable to use that knowledge?
Horrific torture and unfathomable experiments perpetrated by the USA/CIA are finally coming to light. While seemingly disconnected, they mosaic into a terrible picture for terrible times by terrible people -- a self-fulfilling agenda of "exceptional" decisions by covert agencies, the military and pathological politicians. We will not be asked permission. It goes beyond brinkmanship. As stated in the above video, the CIA "would do the same again today." Maybe worse. Undoubtedly worse.
