Macbeth is a play about ambition run amok. The weird sisters' prophecies spur both Macbeth and Lady Macbeth to try to fulfill their ambitions, but the witches never make Macbeth or his wife do anything. Macbeth and his wife act on their own to fulfill their deepest desires. Macbeth, a good general and, by all accounts before the action of the play, a good man, allows his ambition to overwhelm him and becomes a murdering, paranoid maniac. Lady Macbeth, once she begins to put into actions the once-hidden thoughts of her mind, is crushed by guilt.
Both Macbeth and Lady Macbeth want to be great and powerful, and sacrifice their morals to achieve that goal. By contrasting these two characters with others in the play, such as Banquo, Duncan, and Macduff, who also want to be great leaders but refuse to allow ambition to come before honor, Macbeth shows how naked ambition, freed from any sort of moral or social conscience, ultimately takes over every other characteristic of a person. Unchecked ambition, Macbeth suggests, can never be fulfilled, and therefore quickly grows into a monster that will destroy anyone who gives into it.
Ambition Quotes in Macbeth
That tend on mortal thoughts! unsex me here,
And fill me from the crown to the toe, top-full
Of direst cruelty; make thick my blood,
Stop up the access and passage to remorse,
That no compunctious visitings of nature
Shake my fell purpose, nor keep peace between
The effect and it! Come to my woman's breasts,
And take my milk for gall.
To prick the sides of my intent, but only
Vaulting ambition, which o'erleaps itself
And falls on the other.
Creeps in this petty pace from day to day
To the last syllable of recorded time;
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life's but a walking shadow, a poor player
That struts and frets his hour upon the stage,
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
