Who was good/evil in chapter 7 in Lord of the Flies?

If you're asking which character is both good and evil in this chapter, the character would be Ralph. There's a specific point in this chapter where Ralph joins in the hunt, wounds the pig, and briefly feels like he's a part of the group. Like the rest of the boys, he gets carried away by the excitement..... but that excitement and uncivilized behavior is quickly shed in favor of his better side.
