I have seen no concrete evidence of andrenochrome or torture to extract it.
However, there is more than just circumstantial and anecdotal evidence out there that people are being manipulated through fear. The evidence for this is overwhelming and has always been the case throughout history.
Whether evil feeds off fears or not,i don't know or care,but you can aee the negative consequences and reactions of fear used for gain by those who manipulated the public. Massive amounts of wealth and power are derived from fear.
