and your maids, could not fill up/The cistern of my lust, and my desire...(IV, iii, 60-63)
He continues to state that he possesses no admirable qualities of rulers, no fairness, honesty, kindness, strength of character, stability, devotion, bravery, or patience:
But I have none: the king-becoming graces,/ As justice, verity, temp'rance, stableness,/Bounty, perseverance, mercy , lowliness, /Devotion, patience, courage, fortitude,/I have no relish of them, but abound/In the division of each several crime/Acting it many ways (IV, iii,91-97)
But when Macduff responds with a cry of despair and hopelessness for his country, Malcolm tells him that what he has said is a lie, the first lie he has ever told:
Macduff, this noble passion,/Child of integrity, hath from my soul/Wipe the black scruples, reconciled my thoughts/To thy good truth and honor. (IV, iii, 115-119).
Malcolm then goes on to state that he is
yet/ Unknown to woman,,,,scarcely have coveted what was mine own,/At no time broke my faith, would not betray/The devil to his fellow, and delight/No less in truth than life(IV,iii,124-128).
After Malcolm declares that he does, indeed, possess virtue, Macduff is nonplused and says that he does not know what to believe: "Such welcome and unwelcome things at once/'Tis hard to reconcile" (IV,iii,137-138).
However, Malcolm is what he says he is. For, he later encourages Macduff to use the sudden news of his family's slaughter as a reason to fight Macbeth. And, he assumes the role of kingship with dignity and honor in the final act. In his final speech, he inaugurates a new era for Scotland:
As calling home our exiled friends abroad/That fled the snares of watcful tyranny,/...We will perform in measure, time, and place:/So thanks to all at once and to each one,/Whom we invite to see us crowned at Scone (V,iii,66-75).
