How was Macbeth destroyed in Shakespeare's Macbeth?

Primarily Macbeth was destroyed by his own "vaulting
ambition". An exceptionally gifted soldier and an widely admired general of the Scottish
king, Duncan, Macbeth had nurtured a secret ambition to become the king. The
"supernatural soliciting" of the witches after his exemplary victory in the battles
spurred the passion-horse of his ambition. Equipped with the hardened logistic and
emotional support of his wife, Lady Macbeth, Macbeth killed Duncan to usurp the throne.
but a man both fair and foul, Macbeth was sharply self-divided between his unscrupulous
ambition and his moral conscience. Suffering from a sense of insecurity and fear,
Macbeth gets Banquo killed, but Banquo's son escapes the killers. Macbeth moves from to
fear and betrays his murderous nature at the coronation banquet before all the nobles of
Scotland. He unleashes a reign of terror through bloodshed and murder. Macduff's wife
and sons are also ruthlessly put to death. At last the retribution overtakes Macbeth and
Lady Macbeth. The latter becomes a victim of somnambulism and kills herself. Macbeth
goes down to defeat and death at the hands of Macduff, as Duncan's son, Malcolm, leads
an English army to the Dunsinane hill for the ouster of the usurper king of Scotland.
Macbeth is thus destroyed as an example of self-damnation, his own "foul" engulfing the
"fair" in him.
