Final answer:
Nick Carraway concludes that the characters in 'The Great Gatsby' are unique in their own moralities and flaws, and Gatsby's story is individual yet universally meaningful due to its relatability with common human experiences.
Step-by-step explanation:
Nick Carraway, the narrator in F. Scott Fitzgerald's The Great Gatsby, observes the reactions of Gatsby, Tom, and Daisy after the accident and comes to important conclusions about their characters. Fitzgerald portrays these characters in a way that suggests they are not meant to represent broader societal classes or types, but instead embody their own set of morals and flaws.
Gatsby's 'greatness' is a unique concept, his story personal yet universally meaningful due to the common human experiences it touches on, such as the pursuit of unattainable love, the allure of money, and the struggle with individual identity. Through Nick's eyes, we see a critique of the era's moral decay, which Fitzgerald symbolizes through the use of colors and environments in his descriptions. Gatsby's rise and fall, as well as the characters' responses to the tragic events in the story, highlight these themes while leaving the intricacies of their intentions and truths tantalizingly out of reach.
