There is definitely a strong man vs. nature conflict in "Lord of the Flies." Golding seems to be positing that nature bears an indifference to man's daily struggle. For instance, during the scene where the boys brutally kill the sow, the butterflies are described as still fluttering peacefully nearby. Also, the weather and surroundings are typically described as holding such beauty, all the while the boys are descending deeper and deeper into the darkness of mankind. There are times, however, when the heat is described as oppressive, bearing down on the boys. This is mostly found before the storm that erupts, during which Simon is savagely killed. Clearly, there is some pathetic fallacy going on there!
