Answer:
Step-by-step explanation:
The great thing about any Shakespearean Play is that there are always alternatives to any answer to any question. So in this case, her mental state is really a two edged sword.
I'm sure she did not fully see what the consequences of her part in Duncan's murder would be. To her, it was a simple matter of killing Duncan which would lead Macbeth from being Thane to King.
She sounds tough as she urges Macbeth to commit the dead. There's nothing I know of that contradicts that stance.
But what she finds out is that Macbeth has
- powerful enemies
- witches who are very crafty
- witches whose power Macbeth has not taken into consideration.
- witches whose prophecies Macbeth does not take the trouble to interpret
Lady Macbeth is not told enough to make her cautious. All she sees is the crown. I do not like her very much, but I do pity her.
