Observations from act one (Macbeth)

 At scene 5, Lady Macbeth says she wanted to be a man to commit the murder of Duncan, because, according to her, a man would be more appropriate to commit the crime.

At scene 7, Macbeth is not sure about killing the king. He thinks that it would be very wrong if he, one of the men that the king trusted the most, murdered the king. But when he says that to his wife, Lady Macbeth convinces him that this is the right thing to do, telling him to be a man.

Conclusion: is Lady Macbeth maybe disappointed with her husband because he is not being the man she conceives/ he is not being the ideal man for her?
Conclusion 2: we can observe that Macbeth is a good person by the fact he thinks twice before murdering the king. But we can see that he has a defect too: he can be convinced easily, as he accepts to kill Duncan even if this is against his principles. It shows that Lady Macbeth can easily manipulate him.
