Powerful imagery in Lord of the flies chapter 8

I think the most powerful image in chapter 8 is when Simon faces The Lord of the Flies. Many critics have noted that the scene resembles the New Testament's telling of Jesus' confrontation with Satan during his forty days in the wilderness. Simon, a naturally moral, selfless character, does seem to be a Christ-figure who, in his knowledge of the true nature of the beast, is the sole bearer of truth at this point in the novel. In this scene with the pig's head, represented as evil, he meets and struggles against his antithesis. His eventual sacrifice, again an allusion to the crucifixion of Jesus, will mark the triumph of evil over good on the island.
