Lord of flies why Sam and Eric think a harmless dead pilot hanging from a tree is a beast?answer with quotes

he dead parachutist appears to the boys as a supernatural creature; Golding enforces the twins' interpretation by describing the dead body with mystical imagery and language. The body appears to lift and drop its own head, and the flapping parachute opens and closes in the wind. Samneric describe it as a "beast," but Golding's opening description, which follows the parachutist as he drifts across the island-as well as the wing-like quality of his torn parachute-implies that he is more akin to a fallen angel. In Judeo-Christian mythology the first fallen angel was Lucifer, who later became Satan, the incarnation of evil. The parachutist thus serves as a symbol of, and motivation for, the evil that is now manifesting on the island. The Satanic function of the dead body is compounded by the violent, tragic action that results from the confusion surrounding its identity.
