Simon

Simon is the most mature of the boys because he does rationalizes and sees through the imaginary beast, he realizes that it is only in the boys minds. He symbolizes a Christ-like figure who is kind and sees truth, but is killed because of barbaracy and ignorence. He had the solution that might have kept order on the island, but is unable to pass it on to the boys when he is killed killed by the group. His role is similar to Piggy's in this manner. This just shows how again, the emotions of the boys prevail in a life threatening situation.
