Apparently this was a Canadian Folklore vampire cannibal which spawned a Psychological disorder that made people believe they where in fact cannibal vampires.....from Canada i would assume.
I am not, but I see nothing ethically wrong with the act of cannibalism, provided of course the person you are eating is dead.
We renamed Wendigos, call them "The Bloc Quebecois" now. Get it? Because they feed off the rest of Canada? On a note that is not the product of muddied logic due to posting late at night, sounds like an ancient zombie story. And it reminded me of a DS game called Devil Survivor that used to kick my ass (Wendigo was one of the first real bosses).
