Answer:
Macbeth’s speech became very famous in many ways.
Step-by-step explanation:
Dagger is a sharp pointed knife. Macbeth’s soliloquy is a famous dagger speech.
Macbeth wanted to become the king and so he planned to kill the king ‘Duncan’ himself. But, in his speech he expressed guilt and hesitance as he was going to kill someone. So, he narrates how he imagines his actions of using a dagger to kill Duncan.
The dagger scene basically shows the evil inside Macbeth and the heinous crime he was going to commit. He tries to justify the thought of murdering Duncan and eventually decides not to kill him, though he was later manipulated by his wife.
