Why was Ralph particularly frightend by Simon's death? Why did all of the boys exept Ralph push knowledge of Simon's death out of their conscious memory?

Golding develops Simon as a Christ-figure. Simon takes on many of the characteristics that Christ had. Simon does not say too much but when he does speak it is to reveal some sort of truth. The death of Simon meant the death of goodness and Wisdom. Ralph wanted to acknowledge this while the other boys wanted ignore their guilt.
