Among the most compelling aspects of the plot of Macbeth is the process by which Macbeth, a noble if ambitious thane at the beginning of the play, degenerates into a murderous, amoral monster by the end. So Macbeth's "good side" is really only evident at the beginning of the play. For example, after hearing the Sergeant's description of Macbeth's exploits in the battle against the rebel leader Macdonwald, for example, King Duncan exclaims, "O valiant cousin! Worthy gentleman!" Some might argue that the Sergeant's account, in which he describes Macbeth basically cleaving Macdonwald in two with a sword, anticipates Macbeth's bloody deeds later in the play, but it also shows the high regard that Duncan has for Macbeth. Moreover, while not exactly his "good side," we do see in Scene 7 of Act One that Macbeth at least has a conscience of sorts, when he expresses reservations about killing Duncan, saying that "he hath honor'd me of late." He has to be goaded into the murder by his wife.
