What does Jack spend all his time doing? What does the author reveal about him during this activity?

Jack spends all his time hunting for a pig. While Ralph is dedicated to building shelters for the group, Jack is determined to become a successful hunter and establish himself as a lone hero among the group. The chapter's beginning follows Jack on a solitary hunt through the forest, which underscores Jack's importance to the novel and explains his preoccupation with hunting. For Jack, hunting is not an instinctive talent but a skill that he continues to develop as the story unfolds. His motives for hunting are disturbing. He hunts not for the ostensible purpose of gaining food to eat but for his personal enjoyment. Golding indicates that there is something tremendously dangerous in Jack's obsession; his expression is one of "madness" when he speaks about his desire to kill.
