What rules does jack reinforce in chapter 5?

With his customary abruptness, Jack stands up, takes the conch from Ralph, and begins to yell at the littluns for screaming like babies and not hunting or building or helping. Jack continues to be an aggressive and destructive force. He restates that he and his hunters are the ones who really do anything important. He again physically threatens Piggy, foreshadowing the eventual violent conflict between the two boys, and he even manipulates the young boys' fear of monsters and ghosts. During the assembly Jack fully abandons the rules and codes of society. Jack doesn't really talk about rules in this chapter more than he promotes anarchy among the boys, leading them on a disorganized hunt for an imaginary beast. While Ralph is appointed leader for his calm demeanor and rationality, Jack gains his authority from irrationality and instinctual fear, manipulating the boys into thinking that there may be a dangerous creature that they should hunt.
