Act III, Scene 1

Macbeth dislikes and fears Banquo because he is noble, intelligent, dedicated, and rational.

Our fears in Banquo
Stick deep, and in his royalty of nature
Reigns that which would be feared. 'Tis much he dares,
And to that dauntless temper of his mind

He hath a wisdom that doth guide his valor
To act in safety. There is none but he
Whose being I do fear, and under him
My genius is rebuked, as it is said
Mark Antony’s was by Caesar. He chid the sisters

When first they put the name of king upon me
