Hubris

Extreme pride or overconfidence

Hubris (from Ancient Greek ὕβρις (húbris) 'pride, insolence, outrage'), or less frequently hybris, is extreme or excessive pride or dangerous overconfidence and complacency, often in combination with (or synonymous with) arrogance. Hubris, arrogance, and pretension are related to the need for victory (even if it does not always mean winning) instead of reconciliation, which "friendly" groups might promote. Hubris is usually perceived as a characteristic of an individual rather than a group, although the group the offender belongs to may suffer collateral consequences from wrongful acts.
