Whiles I threat, he lives./Words to the heat of deeds too cold breath gives."" This is somewhat of a prayer, and Macbeth, although concerned about his soul, tries not to think about what the consequences will bring. .
Although Macbeth admitted in II, i that his intentions are rather grave, other characters throughout the play seem to notice his violent temperament as well. In Act I, ii, 75-78, the Captain notes a previous incident in which Macbeth displayed his warrior-like nature: "For brave Macbeth (well he deserves that name),/Disdaining Fortune, with his brandished steel,/Which smoked with bloody execution,/Like valor's minion, carved out his passage/Till he faced the slave;/ Which ne'er shook hands, nor bade farewell to him,/Till he unseamed him from the nave to th' chops,/And fixed his head upon our battlements."".
Not only does Macbeth want so badly to kill Duncan, but he also desires the assistance of others, namely, Banquo. Macbeth is even prepared to take desparate measures "or, in this case, simply bribe Banquo " in order to secure Banquo's help, as evident in Act II, i, 34-35: "If you shall cleave to my consent, when tis,/It shall make honor for you."" Macbeth is basically telling Banquo that if Banquo joins the cause to kill Duncan, Macbeth will make it worth his while "in other words, he will possibly give him a high role in society. Banquo, however, responds rather hesitantly, saying that he would rather keep his "bosom franchised and allegiance clear."".
Although Macbeth does not necessarily lack definitive heroic qualities, he does lack qualities that enable him to be liked by the reader. He is not very warm, compassionate, or considerate of others, beside himself. According to Aristotle, however, a tragic hero has to fall from grace from a high position, and after the fall, he must suffer with dignity. Macbeth does fall from grace, but he does not fulfill the "suffering with dignity- requirement.
