Banquo is a perfect Macbeth

Banquo is a perfect Macbeth. Banquo is a foil. A foil is a person how follows the same storyline as the protagonist but makes different decisions.

BANQUO Good sir, why do you start and seem to fear.  Things that do sound so fair? (to the WITCHES) I' th' name of truth, Are ye fantastical, or that indeed Which outwardly ye show? My noble partner You greet with present grace and great prediction Of noble having and of royal hope, That he seems rapt withal. To me you speak not. If you can look into the seeds of time And say which grain will grow and which will not, Speak, then, to me, who neither beg nor fear Your favors nor your hates

This is an example of how banquo had the same path but the witches didn't say anything to him. He also makes a different decision by asking for the witches to make a future telling thing got him to not only Macbeth. Banquo and Macbeth in the beginning of the story fights in the same battle, very well but the king only rewards Macbeth. Then when there was another war they both fought very well, but  again only Macbeth got rewarded. Banquo also makes different decisions in the situation they get into  . Overall Banquo is a perfect Macbeth because he is a foil and has the same situation.
