Macbeth is a lord of Scotland and Thane of Glamis. He is a brave man and is loyal to his king, Duncan. He meets three witches, and they tell him he will be thane of Cawdor and king. Later Rosse ( a messenger) comes and tells him he has been called Thane of Cawdor by the king. Now he wants more, and he will do anything to get what he wants.
I think Mackbeth is a brave man in the battlefield. And people do talk about him like he is: "For brave Macbeth (well he deserves that name- (Act I, scene 2, line 16). A situation that shows as he is very brave is when the norweyan lord sends new supplies of men to battle, he continues fughting, although it was a hard situation. I dont think macbeth is strong sicologicaly though, because we cann see that he is afraid about killing the king and being discovered.
This man has no problem killing people when he is suposed to kill them in battlefield, because they are enemies, neither when there is no a moral problem about it. And we can see he has kill several peoplein the following lines: "with his brandish steel,.
Which smoked with bloody execution."".
These lines are saying that his sword steamed with the blood of those he had killed;.
"Till he unseamed him from the nave to the chaps-.
And in these lines we can see that Macbeth doesn't care about the way he kills, because this is the worst way a prson can kill someone.
.
Macbeth is very loyal to the king until he meets the witches. From this moment on, his ambition captures him and it gets stronger than his loyalty. Now he is going to start thinking about how to kill Duncan. When he is informed that Malcolm is Duncan's heir, his loyalty becomes even weaker, because he wont respect the king's will, and now will needs to get rid of both of them. In the aside he makes in Act I scene 4 , we can see he is not loyal to the king anymore: "Let not light see my black and deep desires-(line 51).
He is confused and doesn't know what to believe about the witches prophecy until Rosse tells him that the king has called him Thane of Cawdor.
