You and your friends are stranded on a deserted island: your food supply has been depleted for days now and...?

I'd go around the length and breath of the island in search of food before I'd eat my friends. To eat them, I'd have to kill them first, and I can't even kill a spider. I put them out the window. Eating human beings is crossing a moral line and is not something I'm prepared to do. What I would do in that scenario is get us all working as a team and hunt for and gather a supply of food for us to cook and eat.
