Hubris n.
exaggerated pride or self-confidence

Etymology: Greek

Seems to be the word of choice to describe the Fall of Eliot Spitzer

But the Spitzer saga is really a boon to literature and religion teachers everywhere. Where else can you see such a classic, right out of Shakespeare and the Greeks, absolutely textbook, flesh and blood demonstration of hubris, the overweening pride that leads, inevitably and inexorably, to the collapse of a public figure?
