What is Simon's role in the story?

Simon

The most introspective character in the novel, Simon has a deep affinity with nature and often walks alone in the jungle. While Piggy represents the cultural and Ralph the political and moral facets of civilization, Simon represents the spiritual side of human nature. Like Piggy, Simon is an outcast: the other boys think of him as odd and perhaps insane. It is Simon who finds the beast. When he attempts to tell the group that it is only a dead pilot, the boys, under the impression that he is the beast, murder him in a panic. Golding frequently suggests that Simon is a Christ-figure whose death is a kind of martyrdom. His name, which means "he whom God has heard," indicates the depth of his spirituality and centrality to the novel's Judeo-Christian allegory.
