Macbeth's Dark Desires and Lady Macbeth's Manipulation
Macbeth knows his thoughts are absolutely wicked, which is why he pleads "Stars, hide your fires! Let not light see your dark and deep desires!" He's literally asking heaven to hide its light so no one can see his evil plans. This shows he's fully aware that what he's thinking is morally wrong.
Lady Macbeth, on the other hand, thinks her husband is far too soft for murder. She describes him as "too full o' the milk of human kindness" - basically calling him too nurturing and pure to do what needs doing. The milk imagery connects to traditional feminine qualities, which she sees as weakness.
That's exactly why Lady Macbeth demands "unsex me here" and asks spirits to "take my milk for gall." She wants to be stripped of all her feminine qualities because she believes only masculine ruthlessness can achieve their goals. It's a fascinating look at how Shakespeare's characters viewed gender roles.
Quick Tip: Notice how Shakespeare uses light vs. dark imagery throughout - light represents goodness and truth, whilst darkness represents evil and deception.
