P2 Macbeth was a reluctant killer, tempted by LM and the witches. He felt regret and recognised the injustice of Duncans death- “wake Duncan with thy knocking, i would thou couldn’t”. before, he was killing only to speed up the prophecy. however, now he is killing despite it. Shakespeare does this to portray his greed-what he has will never be enough, he will never feel secure.
