The overwhelming pride that destroys the tragic hero is called hubris.
Hubris refers to excessive pride or arrogance displayed by a character, often leading to their downfall. Tragic heroes are typically individuals who possess remarkable qualities or achievements but are also flawed in some way. Their hubris causes them to overestimate their abilities or believe they are invincible, leading them to challenge or defy the gods or fate.
In Greek tragedies, the fatal flaw of hubris is a common theme. The tragic hero's excessive pride blinds them to their faults and the consequences of their actions. This ultimately brings about their downfall and a sense of catharsis for the audience.
To summarize, hubris is the overwhelming pride that destroys the tragic hero by causing them to act out of arrogance and disregard the potential consequences of their actions.
