If you and your friends were lost at sea, would any of them decide to kill and eat the rest of you?

150 years ago it was called The Custom Of The Sea, and if you were lost at sea in a life boat with others then once the food ran out, you'd all draw straws to see who would be killed and eaten. This would continue on until you were either rescued or there was only one person left. There was a plane crash in the Andes back in the 80's and the survivors all ate the dead people to keep them alive. But being a vegetarian i'd only eat my friends who were made from vegetables.
