From the moment the boys land on the island, we begin to see signs of destruction. Over and over we are told of the “scar” in the scenery left by the plane. The water they bathe in is “warmer than blood.” The boys leave “gashes” in the trees when they travel. The lightning is a “blue-white scar” and the thunder “the blow of a gigantic whip,” later a “sulphurous explosion.” Now, if you’re trying to answer the big question of whether the boys are violent by nature or were made violent by their surroundings (the island), you could argue that 1) because the island is already so steeped in violence (think the thunder and lightning), the boys couldn’t help but become part of its savagery when they arrived; or that 2) the boys put scars and gashes in the land from the get-go, suggesting they are inherent bringers of destruction and the island is the Eden they destroy.
