Final answer:
The assertion that Lady Macbeth should be admired for her loyalty and faithfulness to the king is false. She is instrumental in plotting the murder of King Duncan, showing her disloyalty and prioritizing her ambition and loyalty to her husband over the king.
Step-by-step explanation:
The statement that Lady Macbeth should be admired for her loyalty and faithfulness to the king of Scotland is false. Lady Macbeth is a complex character known for her perseverance and support for her husband's ambitions in Shakespeare's tragedy, Macbeth. However, her actions show a stark contrast to loyalty and faithfulness towards the king. It is Lady Macbeth who plots to kill King Duncan and convinces Macbeth to go through with the act, displaying disloyalty and betrayal ('When Duncan is asleep...What cannot you and I perform upon The unguarded Duncan?'). Her primary loyalty lies with her husband, Macbeth, and her ambition to become queen, rather than the sitting king of Scotland.
