What leads to the downfall of heros?

The downfall of heroes often stems from their hubris, where excessive pride or confidence leads them to underestimate challenges or adversaries. Additionally, personal flaws, such as a tragic flaw or moral ambiguity, can cause them to make poor decisions that compromise their integrity. External pressures, such as betrayal or manipulation by those they trust, can also contribute to their decline. Ultimately, a combination of these factors can create a tragic arc that transforms a hero into a cautionary tale.
