Fair is foul and foul is fair

For brave Macbeth, Disdaining fortune with his brandished steel, which smoked with bloody execution.

"If chance will have me king, why, chance may crown me."

"Yet do I fear thy nature; It is too full o' the milk of human kindness."

"Come this night and pall the in the dunnest smoke of hell, let my keen knife not see the wound it makes."

"Look like the innocent flower, but be the serpent under't."

"This castle hath a pleasant seat"

"I dare do all that may become a man; Who dares do more is none."

"I have no spur to prick the sides of my intent, but only vaulting ambition, which o'erleaps itself, and falls on the other."

"Is this a dagger which I see before me, The handle toward my hand?"

A dagger of the mind, a false creation,
Proceeding from the heat-oppressed brain?

"Will all great Neptune's ocean wash this blood clean from my hand?"

"A little water will clear us of this deed"

"I fear thou playst most foully for't"

"O full of scorpions is my mind my dear"

"The time has been that when the brains were out; the man would die"

"Out damned spot"

"All the perfumes of Arabia will; not sweeten this little hand"
