Act 2 Scene 1
Brutus's lines 10- 35
pg 62 .

Brutus It must be by his death;and for my part,
I know no personal cause to spurn at him,
But for the general.He would be crown'd :
How that might change his nature, there's the question.
It is the bright day that bring forth the adder,
And that craves wary walking.Crown him?- that?
And then,I grant, we put a sting in him,
That at his will he may do danger with.
Th' abuse of greatness is when it disjoins,
Remorse from power; and to speak truth of Caesar,
I have not known when his affections sway'd
More than his reason.But 'tis common proof,
That lowliness is young ambition's ladder,
Whereto the climber upward turns his face,
But when he once attains the upmost round,
He then unto the ladder turn his back,
Looks in the clouds, scorning the base degrees
By which he did ascend .So Caesar may ;
Then lest he may,prevent.And since the quarrel
Will bear no colour for the thing he is,
Fashion it thus : that what he is, agumented ,
Would run to these and these extrimities;
And therefore think him as a serpent's egg,
Which hatch'd would,as his kind, grow mischievous,
And kill him in the shell.

In this passage,Brutus is trying to conivnce himself on why killing Caesar is such a noble cause,because Brutus is all about honor
