William Golding's Lord of the Flies is the story of English schoolboys who are left stranded on a tropical island after a plane crash. There are no adults on the island and the boys have to learn how to survive together in this environment. The death that happens in chapter eleven of the novel is the third (and final) death, and it is quite different from the first two in several ways.
The first death occurs when the boys light a signal fire that gets out of control; after the boys recover from the conflagration, they realize that one of the young boys, a boy with a mulberry birthmark, is no longer with them. They are sad at the discovery. The second death is Simon's. He is killed on a stormy night as he crawls out of the forest right into a circle of chanting, frenzied boys; while they know the boy is not a beast, they are caught up in the emotion of the moment and they kill him. The next day, Ralph, at least realizes the enormity of what they did. Piggy disagrees, but Ralph says, “That was murder.”
The third death is different. Unlike Simon's death, Piggy is killed during the day. Unlike the little boy's death, everyone is aware of it as it happens. Piggy's death is deliberate and premeditated. When the boys in the fort use the lever to drop the boulder on Piggy, they show no remorse for their actions. In fact, Piggy's death prompts Jack to capture Samneric, the last holdouts other than Ralph, and order his savages to kill Ralph.
No one calls Piggy's death a murder, though it is. The boys show no remorse for the murder, though they should. This death is not like the other two and has much more serious consequences.
I believe is because between the death of Simon and Piggy if you think about it is that the boys showed no regret or shame.
During the assasination of Simon, the boys including Jack felt the fear overcome them of the "beastie" making them kill Simon believing that he is the "beast." They were not exactly sure when and how it happened. 0_0
On the other hand, Piggy's death occured when the boys were having a battle towards Castle Rock. Here at this stage, Jack's boys are not feeling any mercy and as the savages they are becoming, they push a huge rock on Piggy. This demonstrates they no longer know the difference between the hunt for humans and beasts. They have become more like a "beast"....:o
it differs because the boys wanted to kill him, it was not an accident like the other two.
