How Gaddafi was destroyed (in comparison to Shakespeare's Macbeth)?Was it through his own ego or ambition?

This is where a fundamental problem lies in comparing
Macbeth to Gadaffi.  He is still in power.  He hasn't gone anywhere.  He has not had the
epiphany that Macbeth has experienced in terms of the illegitimacy of his power. 
Gadaffi still believes that he is the victim of a campaign by the West.  He does not
seem to be relenting, even when nearly everyone in the international community is
awaiting his departure from office.  He is not
destroyed.

This becomes the fundamental challenge that will
be there in comparing Macbeth and Gadaffi.  It is because of this that a better
comparison might be with their personalities and how they approach the issue of power. 
One cannot really compare both of their characterizations because Macbeth was destroyed
by his own ambition, something that he, himself, understood all too late.  Gadaffi is
settling in for a while.  He is not leaving and even though the pressure of the world is
on him, he does not seem that he is close to departing from
office.
