What causes jack humiliation chapter 8 lord of files?

Jack is humiliated in Chapter 8 of "Lord of the Flies" because he is forced to confront his own violent nature and the consequences of his actions. He feels guilty about having killed Simon and is filled with shame when the other boys realize what he has done. This humiliation is compounded by the fact that Jack has been idolized by the other boys and has seen himself as a strong and capable leader. However, the realization that he has committed murder and the ensuing consequences shatter this image and leave him feeling vulnerable and exposed.
