Lady Macbeth is a controlling wife. She is selfish, greedy and even dangerous. She manipulates Macbeth into murdering King Duncan. She insults his manhood in order to get him to follow through and murder King Duncan.
At one point, Macbeth has changed his mind about murdering King Duncan:
We will proceed no further in this business.
He has recently honored me, and I now have the
Golden opinions from all sorts of people,
Which I want to enjoy for a bit longer, and
Not cast them aside so soon. (Act I, Scene vii)
To this, lady Macbeth begins to insult Macbeth's manhood:
Are you afraid
To be the same man in reality
As the one you wish to be? Would you have the crown
Which you believe to be the ornament of life,
And yet live like a coward in your own self-esteem (Act I, Scene vii)
Truly, Lady Macbeth does not appreciate the honors King Duncan has bestowed on her husband. She is determined to convince Macbeth to kill King Duncan:
What beast was it, then,
That made you tell me about this plan?
When you “dared” to do it, then you were a man;
And, in order to be more than what you are, you would
Be so much more the man. (Act I, Scene vii)
Lady Macbeth is no lady. She is dangerous. She will not take no for an answer. She is determined to have her way. She does not respect that King Duncan has recently honored her husband. She will stop at nothing to see that she becomes the queen of Scotland. She has murderous thoughts. She seems to have no fear at all. She will not rest until King Duncan is dead. She will manipulate Macbeth until he follows through with the murder. She is not a good wife at all.
she is a good wife in a way that she helped her husband follow his dream to become king no matter what the consequences were.
Partially, he succeeded in killing Banquo but Fleace , upon seeing the murdering of his father had escaped the scene.
