The Ghost Of Banquo In Shakespeare's 'Macbeth'

The ghost of Banquo’s soliloquy to himself after he gains knowledge of who has sent for him to be killed and what it truly means to be evil and how fair is foul and foul is fair. What knowledge has Banquo gained during his short time as a ghost?

Although my life has come to an end, I think this knowledge may allow me to rest knowing that fate is on my son’s side. There isn’t much I can influence in this world as
