In William Shakespeare's Macbeth, the tragic hero, Macbeth, possess nervous irritability, great imagination, and determination. In order to prove this, one can use his own dialogue and actions to support these characteristics.
Nervous Irritability: Macbeth's nervous irritability is irrevocably seen in Act IV, scene i. Macbeth has previously decided that it would be in his best interest to visit the three witches again. His fears regarding being found out for his part in the murder of Duncan are rising. Not only that, his desire to find out more about his future has put him on edge. In order to alleviate his nervous irritability, Macbeth approaches the witches quite harshly--demanding that they tell him of his future.
How now, you secret, black, and midnight hags? What is't you do?
I conjure you, by that which you profess,
Howe'er you come to know it, answer me:
I will be satisfied! Deny me this,
And an eternal curse fall on you! Let me know:
Here, Macbeth's anxiety rises as he makes threatening demands of those who have the ability to help him. Instead of approaching the witches with a calm demeanor, Macbeth comes with great nervousness and irritability.
Great Imagination: Macbeth uses great imagination to describe and move forward with his plan to become king. Not only does he plot, and succeed, to murder Duncan, Macbeth also creates a story to move any suspect thoughts away from himself. In Act II, scene iii, Macbeth creates a string of dialogue which is meant to make others believe that Duncan's death is no fault of his own.
Had I but died an hour before this chance,
I had lived a blessed time;
There's nothing serious in mortality:
Here, Macbeth creates a woeful dialogue, similar to a statement made to remove him from being suspect. Determination
: Macbeth's determination is seen throughout the play. First, after hearing the prophecy, Macbeth decides that the throne will be his. He is willing to do anything to gain the throne (including murdering the king and some of his "followers"). Not only does Macbeth murder for the throne, he is willing to revisit the witches in order to find out more about his future. In the end, Macbeth is willing to give his own life to insure his place as king. Essentially, Macbeth is willing to do anything it takes to keep the throne.
