Banquo’s nolbility is made explicitly clear throughout the play, and Shakespeare consistently holds him up as an example of ideal morals for in the face of normal humanity.Though he struggles against temptation, his good morals and noble character wins out, and he makes the morally correct choice to stop supporting Macbeth. Banquo is described to have a ”royalty of nature’’, emphasising his noble and majestic nature. This idea is compounded shortly after, when Macbeth describes him as “wise”, implying a rational and intelligent character.
