From the passage, the reader can safely infer that the porter is a comic character.
Step-by-step explanation:
- In this story, the porter plays for comic relief by reducing the tension of the audience on the murder of the king Duncan.
- The porter also indicates the gates to Macbeth's home. The porter was a drunken character and he has a lively imagination.
- This porter character will speak humorously about his superiors. He only led Macduff into the Macbeth castle.
