It may seem dark, but I love this idea. Just think, your food supplies are raided by a bearger and your only friend is killed. Almost starving, wouldn't you eat him to survive, at the cost of your sanity? There could also be a couple more uses for human meat (none of which I have thought of). There are some issues though. For example, what would WX78 drop? Hes not made of meat, although, his abilities are not quite as great compared to others. A compensation could be to make him drop boards and gears, rather than sanity inducing meat. If a perma-death system is implemented rather than a perma-respawn system, he could be farmed for gears in return for Wilson's beard hair. (From meat effigies). I haven't quite worked out the ups and downs of this specific dilemma, but it seems like a valid starting point to perfect this plausible system. I hope cannibalism gets into the game, and that it is gone about correctly.
