Why does Simon feel shame for giving Piggy meat Jack rage at him in lord of the flies?

In William Golding's novel "Lord of the Flies," Simon does not feel shame for giving Piggy meat, rather, it is Piggy who feels ashamed of his own greediness and fear. Jack lashes out at Simon because Simon represents moral goodness and innocence, which starkly contrasts with Jack's increasingly savage nature and desire for power. Jack's rage is a symbolic attempt to suppress the guilt and internal conflict he feels due to his own actions and motivations.
