In chapter 9 what does the village by the ocean show you about humanity? what is the purpose of this scene?

They continue down the beach to find a small village, but no inhabitants. All evidence points to a hurried and recent evacuation. Suddenly, a group of fishermen spring from their cover and seize the boys. The villagers have heard rumors that a young band of rebels are in the area, and accuse the boys of being hostile. After interrogating them, the fishermen take the boys’ shoes and send them away. This is very sad that villagers are so terrified of child soldiers that they have forgotten their humanity even when they know the boys are innocent.
