In the tragic drama Macbeth, written by William Shakespeare, the hero, Macbeth, constantly has attitude changes from the beginning until his death at the end of the play. Because of his change of character from good to evil, Macbeth's attitude towards other characters, specifically Duncan, Banquo, Lady Macbeth, is affected.
             The first of the four characters is Duncan. Since Macbeth interacts with Duncan only a minimal amount before Duncan's death, Macbeth's attitude towards him changes very rapidly. Before Macbeth hears the witches' first prophecy, he is very close to Duncan, and would never even think of doing something against him. When the thought of murdering Duncan crosses his mind immediately after he finds that he has just been named Thane of Cawdor, he cannot believe he "yield[s] to that suggestion Whose horrid image doth unfix my hair And make my seated heart knock at my ribs" (I, iii, 133-35). In scene 5 of act 1, however, his ambition is starting to take over, but partly because of his wife's persuasion. He agrees that they must "catch the nearest way" (17), and kill Duncan that night. However when the time for murder comes, he begins giving himself reasons not to murder Duncan:
             First, as I am his kinsman and his subject,
             Strong both against the deed; then, as his host,
             Who should against his murderer shut the door,
             Not bear the knife myself.
             When Lady Macbeth enters, though, she uses her pursuasive techniques to convince Macbeth that this is the right thing to do. He then tells her that "I am settled." (79). He is firmly seated in his beliefs that killing Duncan is the right thing to do-until he performs the murder. He is so horrified by this act that for a moment he forgets where he is or who he is with. We learn from this murder that Macbeth truly had faith in the king and was very loyal, but under the forces of his wife's persuasion
