Our view of Macbeth

at the start of the play we meet the three witches who plot to meet Macbeth after his battle but as soon as they arrive they then leave, there is some thought of imagery and paradox for example when they say "fair is foul and foul is fair" is this talk about the weather or what is to come during the rest of the play to Macbeth is he really the brave army general we are lead to believe from act 1 scene 2 or is there a more twisted side to him that only the three sisters know about, We could say that is this why he is in the army because he does have this violent side and by fighting he has it under control and when there is no war all it takes is for an idea that gets his blood flowing for violence. here that In act 1 scene 2 we see from Duncan and the Sargent that they see Macbath as a brave and loyal general in his army. The captain then describes for Duncan how Macbeth slew the traitorous Macdonwald. line 9- 26. and for his reward he then becomes the than of cawdor. there are many sides to Macbeth and many have argued different sides for this argument 

Hi William, thanks for your answer, it contains a lot of insight.   I particularly liked what you said about the witches saying "Fair is foul and foul is fair" introducing an element of uncertainty and ambiguity in the play and suggesting that there is a darker element to Macbeth's character that only those on the dark side know about.Food for thought!  Thanks, Peter
