A person may have many roles in their life that they must fulfill. For instance, being a friend, co-worker, father, mother or a citizen, are all roles a person may possess. Due to different circumstances and situations, one may have to gain or lose roles and their current roles may change. William Shakespeare gives Macbeth a number of roles in which they change during different times and situations. In Macbeth's life time he plays and important role as a husband, a leader, and a friend. .
Macbeth's role as a husband changes from the beginning of the play till the end. Macbeth is seen as a loyal and caring husband towards Lady Macbeth. In his letter to his wife about the witches prophecies, Macbeth writes, "This have I thought good to deliver thee, my dearest/ partner of greatness that thou mightst not lose the/ dues of rejoicing, by being ignorant of what greatness/ is promised thee" (1.5.10-13). In this scene one can see Macbeth's faith and loyalty to his wife as he immediately writes to Lady Macbeth about it. In the husband and wife relationship Lady Macbeth is considered to be the one wearing the pants in the relationship and it is obvious that Macbeth is the one who is being controlled. When Macbeth states, "we will proceed no further in this business: He hath honoured me of fate." (1.7.31-32), Macbeth shows a bit of weakness as he does not want to go through the murder of Duncan. However, Lady Macbeth is the one who questions his manhood and intimidates Macbeth which allows him to be convinced. Nonetheless, after Macbeth becomes king, he gains new confidence and makes his own choices without even consulting his wife, Lady Macbeth. As Macbeth says, "For Banquo's issue have I filed my mind;/ For them the gracious Duncan have I murdered" (3.1.70-71) he realizes the potential threats he has of his powers and makes a decision himself to kill Banquo. As the play progresses further, Macbeth realizes that his ambition has led to nothing he expected, which causes him to lack concern of his wife.
