Answer:
Lady macbeth says that she could not commit the murder because duncan "looked like my father while he slept" this shows that she is not as ruthless as she appears to be.
Explanation:
L. Macbeth never planned killing the king herself. Although she tells Macbeth to just sit there, “look like the innocent flower and leave the rest to me”, we can see that she is full of talk and bravado.. L. Macbeth leaves the dagger waiting for Macbeth. At a particular point, she states that she would have done it herself if the old king had not resembled her father. This, however, seems more a pathetic excuse to convince herself that she is ruthless rather than anyone else.
