Answer: Jack, having just killed a pig, is too excited by his success to care very much about the missed chance to escape the island. Indeed, Jack’s bloodlust and thirst for power have overwhelmed his interest in civilization. Whereas he previously justified his commitment to hunting by claiming that it was for the good of the group, now he no longer feels the need to justify his behavior at all. Instead, he indicates his new orientation toward savagery by painting his face like a barbarian, leading wild chants among the hunters, and apologizing for his failure to maintain the signal fire only when Ralph seems ready to fight him over it.
