In Act I, Scene vii, of Macbeth, one can effectively compare and contrast Lady Macbeth and Macbeth.
First of all, Lady Macbeth seems to be the stronger of the two. She questions Macbeth's manhood. It is here where readers see the power that she holds over her husband. Lady Macbeth knows of the prophecy and she seems determined to get it for her husband. While Macbeth states that he is man enough, she questions his ability to gain the crown.
Macbeth, in this scene, comes across as the weaker of the two. While he states that he is indeed man enough, he fails to prove it verbally to his wife.
Here, both characters seem to know the other character better that they know themselves. Lady Macbeth knows that her husband is not strong enough. Macbeth knows that she will not rest until she gets what she believes is due comes
The only similarity which one can make in regards to these characters is the fact that they both want more power. Little can be said about the similarities between the two in this scene.
