thats a good question to hear an answer for from someone in the know. i would guess pertaining to tribal beliefs it would be solely for personal gain or to enact revenge or harm upon ones enemies. maybe goose will fill us all in a little more. from the werewolf stand you would have to probably start with the epic of gilgamesh and work your way from there... curses and all. which makes ya wonder if its still a curse or now a lineage... (if possible of course)....lol.What would be the goal?
