Chapter Four contains the turning point of Ralph and Jack's relationship. Whilst previously Jack had respected Ralph's leadership despite some initial strains over such issues as hunting vs. helping with hut building, by the end of Chapter Four the situation had substantially changed. Jack is flushed with success after finally killing a pig, and the humiliation he feels over Ralph's admonishment over neglecting the fire is more than he can bear. The reenactment of the hunt is both a way for Jack to escape Ralph's brooding anger and to relive the primal joy he felt from the first successful hunt.
Ralph is intensely annoyed and frustrated by the neglect of the fire, and only being able to stand by and watch as the boys perform their reenactment of the hunt only further darkens his mood,
Then Maurice pretended to be the pig and ran squealing into the centre, and the hunters, circling still, pretended to beat him. As they danced, they sang.
"Kill the pig. Cut her throat. Bash her in."
Ralph watched them, envious and resentful. (p.94)
The author includes the reenactment of the first successful hunt to both highlight the huge rift between Jack and Ralph, and to show how the boys through their chanting and actions are moving beyond just playing a game; the violence and bloodthirsty nature of killing a wild beast is not something they recoil from but rather embrace with wild enthusiasm. The reenactment of hunting represents a dark foreboding of what will come in later events.
