In Golding's classic novel, Jack and the majority of the boys reject Ralph and his attempts to establish a civilized society in favor of hunting pigs and living like savages. The primary appeal of rejecting civilized society is the freedom to do whatever the boys please and refrain from difficult, mundane tasks. For example, the majority of boys do not feel like following the rule established to keep the coconuts full, they do not enjoy maintaining the signal fire on top of the mountain, and do not feel like helping erect shelters on the beach. Instead, the boys prefer the excitement of hunting and relaxing by the lagoon, which is why they dismiss Ralph's directives and begin to follow Jack. The boys also enjoy the freedom to live exactly how they want without following any specific rules or answering to someone else.
Another possible explanation as to why a person might reject civilization concerns the ability to exercise their power and authority over others. For example, Jack desires to rule as a merciless tyrant and control his subjects through fear and violence. In a civilized society, Jack would not be able to exercise his authority or satisfy his inherent desire to overpower and harm others. Characters like Jack and Roger thrive in a lawless society, where they are alpha males capable of defending themselves and intimidating others.
Overall, individuals looking to avoid manual labor and following rules would be motivated to reject civilized society along with powerful, hostile individuals who are only interested in ruthlessly exercising their power over others.
