Who is legitimately hurt when the boys re-enact the pig spering?

When the boys re-enact the pig spearing in "Lord of the Flies," the legitimate hurt is primarily inflicted upon Simon. This act symbolizes the loss of innocence and the descent into savagery, as Simon, who represents morality and insight, becomes a victim of the group's primal instincts. The brutal nature of the re-enactment not only results in Simon's physical harm but also signifies the emotional and psychological damage inflicted on the boys themselves, as they lose their grasp on civilization and humanity.
