In Macbeth, what quotes represent the hubris? (macbeth's excessive pride)

Hubris can be considered more than excessive pride in a person.
Hubris can also be too much ambition or even over confidence in a
character.

Macbeth is a prime example of a man filled with pride,
ambition and confidence. The reader sees this right from the start of the play. As soon as
Macbeth is named Thane of Cawdor,fulfilling one of the witches prophesies, he begins to
contemplate how to become king as the witches have suggested. The fact that he wants to be king,
and kills to become king, shows his ambition.

The second set of
prophesies allow the reader to examine Macbeth’s overconfidence. When the trees begin to march
against him as the witches warned, Macbeth still believes that he will live. He leaves the castle
with armor on his back and fights to keep his power. Even though the witches have tricked him
once, he still believes he is invincible as the witches told him. He fails to think about the
ways the witches have tricked him. This shows us that he is confident of his success, yet since
he is eventually killed by Macduff, we can see that his confidence was misplaced (an example of
hubris).

Hope this helps. Good luck!
