Heroes with flaws that lead to their downfall?

Heroes with flaws often exhibit traits that, while initially seen as strengths, ultimately contribute to their downfall. For instance, excessive pride can blind a hero to their vulnerabilities, leading them to underestimate their foes or ignore wise counsel. Similarly, a deep-seated need for revenge might drive a hero to make reckless decisions, resulting in tragic consequences. These flaws add depth to their character, illustrating the complex nature of heroism and the fine line between virtue and vice.
