What is Brutus' reasoning for asking all of the following questions in the quote below?
Did not great Julius bleed for justice' sake?
What villain touched his body, that did stab,
And not for justice?
What, shall one of us,
That struck the foremost man of all this world
But for supporting robbers, shall we now
Contaminate our fingers with base bribes,
And sell the mighty space of our large honors
For so much trash as may be grasped thus?
I'd rather be a dog, and bay the moon,
Than such a Roman. (4.3.19-27)
