LOTF Ch.9

Lord of the Flies: Chapter 9 (A View to a Death)
The chapter starts out with Simon in his hidden fort in the woods, hallucinating the the Lord of the Flies. He stumbles wearily through the forest until he reaches the base of the mountain. Part way up, the wind filled the fallen man's parachute, bringing it into Simon's sight. Here Simon realizes that there really is no "beast", just the dead man. Staggering with weakness he starts down the mountain to tell the other boys of his discovery. Ralph and Piggy eventually make their way to Jack's party. Just before their dance around the fire, Jack essentially takes over the group for good, saying his tribe will have food, drink, fun and be protected from the beast. They continue to the dance where the hunters act out the killing of a pig, including their creepy chant. They were so hyped up from the feast and dancing that when Simon appeared, screaming about the dead man on the hill, they mistook him for the beast. All the boys jumped at him, tearing him apart. On top of the mountain, the wind blew and captured the parachute again. The dead man was carried away, out to sea. A little later, the tides came in, sweeping Simon's dead body out to sea as well.
This whole chapter is proof of how savage and out of control the boys have become. Jack is almost blackmailing the other boys to join his tribe (I fed you, now will you join my tribe??) and they all play a part in killing one of the most valuable people on the island, even Piggy and Ralph. Jack's tribe has a dance and chant about murdering pigs and beasts and Simon is hallucinating a huge fly on a stick. It honestly seems like they have all completely lost their minds, or at least their humanity.
