Simon is killed at the end of Chapter 9. At the beginning of Chapter 10, Ralph and Piggy have trouble even bringing it up. They start by talking about Simon's death in whispers. They reluctantly begin to discuss it.
Ralph and Piggy feel incredible guilt about having taken part in the mob's attack on Simon (however much they did take part). Initially, it is mostly Piggy who tries to convince Ralph (and himself) that Simon's murder was an accident. Ralph insists it was murder and recognizes that things are really starting to fall apart:
I'm frightened. Of us. I want to go home. Oh God, I want to go home.
When Sam and Eric arrive, they are also reluctant to acknowledge what happened. They speak of the feast, not the murder. With all four of them, part of this reluctance (and lying) is guilt and another part is fear of acknowledging how bad things have gotten: that is, how savage the group has become.
In chapter 9 of the book The Lord of the Flies, Simon finds the dead parachutist's body and decides to let Jack and the rest of the boys know that it is a man not a beast. He tries to make his way back to the campfire, where a huge feast is about to take place. A storm is blowing in and the darkness is falling fast on the island. Simon stumbles his way towards the camp with the parachute with him. Ralph, Piggy and the other boys go and join Jack, to try to keep things under control. Things get wild at the feast and all the boys start dancing and chanting around the fire, even Ralph and Piggy. When Simon comes in, the boys think he is the beast and jump on him and kill him.
Ralph and Piggy have a hard time coming to terms with their part in Simon's death. It means that they are now becoming like Jack and the other boys. Piggy can't handle his part, so he says it was a terrible accident. They say it was dark and didn't realize it was Simon. Ralph knows that with the death of Simon, it is an end to his innocence. All the kids' innocence is lost.
"Surrounded by a fringe of inquisitive bright creatures, itself a silver shape beneath the steadfast constellations, Simon's dead body moved out toward the open sea."
The death of Simon is the end of everything the boys knew. Simon was a complete innocent and the boys killed him savagely. The real question is rather the boys will ever be able to be what they once were.
- Ralph, Piggy and Samneric all participated in the chants and had their share of the meat; deep down, they knew they should be account for the death of Simon. Guilt overwhelms these boys, and they find excuses to deny themselves of the incident and blame. If they admitted to their actions, it would make them seem like savages.
In the book "Lord of the Flies" the boys were with Jack and his tribe the night of Simon's death. At first they were not going to eat, but they were given food by Jack and so they were hungry and ate it. The boys began to dance around the fire and became almost entranced as they began to chant about killing the beast. Simon entered from the woods at an inconvenient time because the boys were startled and thought it was the beast.
The boys were so enraged by the event that they continued to beat on Simon and bite and kick at him. Ralph and the other two boys felt terrible guilt about their behavior and Simon's death. They tried to pretend that it was a beast. The boys could not cope with their own level of responsibility.
