Macbeth is brave and very loyal to King Duncan. He does not want to murder the king for more power at first.(1.7.31-32) "We will proceed no further in this business. He hath honored me of late."
Lady Macbeth prayed to be more masculine. She does not think Macbeth is manly enough to kill the king. She questions his masculinity. (1.6.39) "Unsex me here."
Macbeth is not loyal and turns evil. Macbeth gets Duncan's servants drunk and stabs Duncan to death. (2.1.63-64) "Hear it not Duncan, for it is a knell that summons thee to heaven, or to hell."
Lady Macbeth turns evil as well, and helps Macbeth in the killing of Duncan. (2.3.53) "Give me the daggers."

Macbeth goes to the witches for help. (4.1.70) "Tell me, thou unknown power."
Witches gave Macbeth confidence (4.1.79-81) "Be violent, bold, and firm. Laugh at the power of other men, because nobody born from a woman will ever harm Macbeth."
Macbeth mourning the death of his wife. (5.3.14-16) "Go prick thy face and over-red thy fear, Thou lily-livered boy. What soldiers, patch? Death of thy soul!"
Lady Macbeth goes crazy and kills herself. (5.1.53-55) "Wash your hands; put on your nightgown; look not so pale! I tell you yet again, Banquo's buried. He cannot come out on's grave."
