Why do you think Golding decided to have the figure fly over the boys on the beach and into the sea?

Golding likely chose to have the figure fly over the boys and into the sea to symbolize the loss of innocence and the pervasive nature of evil. The figure, representing a dead parachutist, serves as a stark reminder of the adult world's violence and chaos, contrasting with the boys' initial carefree existence. By having it descend from the sky and ultimately disappear into the ocean, Golding emphasizes the fragility of their innocence and the inescapable reality of their situation. This moment foreshadows the boys' descent into savagery and the overwhelming impact of external conflict on their isolated world.
