Fatal Flaw

In classic Greek tragedies, the term hamartia, first described in Aristotle’s Poetics, refers to a fatal flaw in the main character of the drama, which causes a chain of events to unfold: a reversal of fortune from good to bad, and the eventual downfall of the character. One traditional example of such a flaw is hubris, an overblown ego and lack of humility. Write a short story in which your protagonist suffers from an unfortunate degree of hubris. Does overconfident pride blind the character to the consequences of that individual’s actions? Does arrogance lead the protagonist toward one big mistake, or several small errors that lead inevitably to tragic misfortune?
