What is the significance of Ralph and Piggy joining the dance? Why do they do this? What is the environment like in this scene and why is the environment important? What is the irony of their actions?

In chapter 9, a violent storm hits the island, and Jack and his hunters begin ritualistically dancing on the beach. The boys work themselves into a frenzy as Ralph and Piggy join the group of dancing boys. Ralph and Piggy feel secure and energized among the hunters as they begin to chant with the other boys. The violence of the storm only increases the hysterical atmosphere as the boys dance and yell wildly into the sky. The chaotic atmosphere and severe weather mimic the unrestrained emotions of the savage boys. Suddenly, Simon stumbles onto the beach from out of the forest, and the group of boys mistakes him for the beast. The boys surround Simon and begin to rip, stab, and tear the defenseless child. Ralph and Piggy participate in the frenzy and take part in Simon's unmerciful death. Ralph's and Piggy's participation in the ritualistic dance and brutal murder of Simon is ironic because they are both depicted as the most civilized individuals on the island. The fact that Ralph and Piggy participate in Simon's murder emphasizes Golding's negative view of humanity, and possibly the belief that all humans are inherently wicked.
