It always stroke me as odd that no-one attempted to kill somebody else on Survivor.
You're all on a stranded island, no food, no shelter, who's going to stop you? And what do you have to lose? You're in the middle of nowhere where rattlesnakes are your neighbors and rats are your pillows, you definitely don't want to hear some idiot's vicous gossip about someone else or the whore trying to get pounded meanwhile she's more dirty then a pig in the mudpile..
