OK, I'll try.
Cannibalism was a common practise, as was headhunting, in the South Pacific. Two of their milder practises. To a Western mindset, difficult to understand. Dig into it a bit, and you find that there were reasons -- good reasons -- why they did this. From "our" viewpoint, evil reasons, completely foreign to our experience as a Civilization. From theirs, it made perfect sense.
Difficult to describe what I mean by this Evil: it's something you almost need to feel and be attuned to experientially.
Ever read Goulding's "Lord of the Flies?" It comes about as closely as possible to what I mean.
I loaded crude oil from an offshore submarine hose in Borneo once. Locals came on board to haul up the hose and connect it to our ship's headers. The pilot mentioned that the workers were only a generation or two away from (past) cannabalism practices.
They had nice teeth.
The insects that flew on board while we were anchored were huge. One night an insect which was the size of a small bird flew screeching into the pilot house and scared the H out of the mate on watch.
