F. Scott Fitzgerald uses the characters to show how dreaming about something changes the entire psychological and emotional construction of an individual, leading him to the despair that makes him do anything to achieve that dream, even something immoral and improper. This is clear in Gatsby, who through his dream of social ascension, ends up taking very immoral attitudes, these attitudes are reinforced by his dream of being with Daisy. This quest for ascension and achievement becomes more and more desperate, because it seems increasingly distant, even though Gatsby has already achieved most of his goals. F. Scott Fitzgerald shows how uncontrolled despair, guided by desire, can cause tragedies and irreparable losses, as happened with Gatsby, who so much pursued his goals in non-commendable ways, had a sad and undesirable ending.
