LOTS OF SPOILERS!!!
So your plane crashes next to a deserted island. Some die, some get hurt, some are okay. You have plenty of salvaged luggage, an amount of food and water, and plenty of stuff to make shelters from. Within two days you've decided to kill of the injured people to conserve water and someone's committed suicide?! Blimey! What happened to planes having transponders or flight plans, or perhaps a relative wondering why your flight never made it? They have a flare gun and a life raft so the obvious thing to do is swim to the other island a mile away. Repeatedly. It only takes them ten days to start killing each other. Heck, by day eleven they probably would have eaten the bodies :/
