Morality, Values, and Lifestyle of Society in The Great Gatsby Morality, values, and lifestyle played a major role in developing the plot of The Great Gatsby. Fitzgerald used it in order to give the reader a clearer meaning on who the characters in the book really are, rather than what they act like. By putting emphasis on these aspects of the characters, the reader sees how much the characters differ from each other and the way it effects their relationships with each other. Morality is defined as a system of ideas of right and wrong conduct. The Buchanans, Jordan Baker, Gatsby, and Nick each have different sense of morality. Daisy Buchanan, Tom Buch
