Evil/Banquo

Question 1

“​I fear thou played’st most foully for’t​”

“​cursed thoughts​”

Answer 1

Banquo suspects Macbeth but doesn’t speak out as he states “​I fear thou played’st most foully for’t​”. He suspects Macbeth because he can​ identify evil as a moral person​. Or, perhaps, he suspects Macbeth because it’s what Banquo would have done in Macbeth’s position, as he had “​cursed thoughts​” himself.
