Both Macbeth and Lady Macbeth refer to water in this scene, but their attitudes are very different. What do their attitudes say about their characters?

MACBETH.Will all great Neptune's ocean wash this blood
Clean from my hand? No; this my hand will rather
The multitudinous seas incarnadine,
Making the green one red.
LADY MACBETH.
A little water clears us of this deed:
How easy is it then!

ANSWER: These lines continue to show Macbeth struggling with committing Duncan's murder. He says that "all great Neptune's ocean" cannot wash the blood from his hands. Lady Macbeth has a "whatever" attitude – showing her cruel nature. She says we'll just wash our hands and be done with it – simple as that. ("How easy is it then!")
