Answer:
Banquo doesn't commit any crime but is murdered at Macbeth's command.
Explanation:
This is the event from Acts 2 and 3 that demonstrates the recurring motif of "fair is foul, and foul is fair." What this phrase shows is that things are not always as fair as they should be. Sometimes, what should be fair ends up being foul, and viceversa. This lack of justice is shown in the case of Banquo. Banquo did not commit any crime. However, he is still murdered at Macbeth's command.
