In "Lord of the Flies," the omniscient narrator gives us a bird's-eye view of the boys' actions and thoughts, which helps us understand their struggles and emotions more deeply. For example, we see not just Ralph's leadership efforts but also Jack's growing desire for power, allowing us to feel the tension and conflict as the boys’ society breaks down.
This narrative style encourages the reader to judge the characters based on their choices and behaviors. For instance, when Jack becomes increasingly cruel and violent, we can clearly see his transformation and decide whether we agree with his actions or prefer Ralph's more democratic approach.
