Umm Lady Macbeth had monster tendencies.
Lady Macbeth: Why did you bring these daggers from the place? They must lie there. Go carry them, and smear The sleepy grooms with blood.
Macbeth: I'll go no more. I am afraid to think what I have done; Look on't again I dare not.
Lady Macbeth: Infirm of purpose! Give me the daggers. The sleeping and the dead Are but as pictures; 'tis the eye of childhood That fears a painted devil.
................
Lady Macbeth: Glamis thou art, and Cawdor, and shalt be What thou art promis'd. Yet do I fear thy nature, It is too full o' th' milk of human kindness To catch the nearest way.

Lady Macbeth: The raven himself is hoarse That croaks the fatal entrance of Duncan Under my battlements. Come, you spirits That tend on mortal thoughts, unsex me here, And fill me from the crown to the toe topful Of direst cruelty!
........................
Lady Macbeth: How now, my lord, why do you keep alone, Of sorriest fancies your companions making, Using those thoughts which should indeed have died With them they think on? Things without all remedy Should be without regard: what's done, is done.
Yeah, that’s her.
