Simon represents the good in all of us.
In Lord of the Flies, Simon is the only character who stands out as a true hero. He is the only one who truly cares about the well-being of others, works to help them, questions their actions and motivations, does not give into savagery and violence, maintains order and civilization on the island, has a connection with nature, sees the beast for what it truly is, does not judge others based on appearance or actions, is able to forgive others even when they have done wrong and see the good in others even when it’s hard.
Simon represents the best version of ourselves—the part of us that wants to do good and help others without any expectation of reward or recognition.
