Based on the information in this reading passage, why would Macbeth be motivated to murder Banquo?
BANQUO. Thou hast it now: King, Cawdor,
Glamis, all, As the Weird Women promised, and I fear
Thou play'dst most foully for't; yet it was said
It should not stand in thy posterity,
But that myself should be the root and father
Of many kings. If there come truth from them
(As upon thee, Macbeth, their speeches shine)
Why, by the verities on thee made good,
May they not be my oracles as well
And set me up in hope? But hush, no more.
[Sennet sounds. Enter Macbeth as King, Lady Macbeth as Queen, Lennox, Ross, Lords, Ladies, and Attendants.]
