Almost any chapter you could choose would show Golding's representation of human nature, however, there are some pretty blatant scenes. For example, the pig's head on a stick....GREAT example. Then there's the section, chapter 8 I think, where Ralph and Jack confront one another. This struggle between Ralph and Jack are the same 'wars' that every human being has....to follow our more base instincts or to adhere to the rule of law. Both have their pluses and minuses as depicted in the story .
