For example, in Macbeth, King Duncan explicitly describes Macbeth as noble and deserving of the title he has just received after defeating the Thane of Cawdor through his line: “What he hath lost noble Macbeth hath won” (Act 1, Scene 4).
For example, again in Macbeth, Macbeth’s soliloquy “But in these cases / We still have judgement here, that we but teach / Bloody instructions, which, being taught, return / To plague th’ inventor” (Act 1, Scene 7) as he reflects on the consequences of murdering King Duncan reveals his internal conflict and indicates that he is not a straightforward villain but a man torn between ambition and guilt.
