Hubris

"hu-bris" [noun] excessive pride or self-confidence; arrogance

"In many myths, mortals who display arrogance and hubris end up learning, in quite brutal ways, the folly of this overexertion of ego. The Greek concept of hubris refers to the overweening pride of humans who hold themselves up as equals to the gods. Hubris is one of the worst traits one can exhibit in the world of ancient Greece and invariably brings the worst kind of destruction." -from the Mythology Study Guide by Edith Hamilton
