Some of the quotes i will be looking at in detail are

“O, name him not. Let us not break with him,
For he will never follow anything
That other men begin.” – Brutus
“For Antony is but a limb of Caesar.
Let us be sacrificers but not butchers, Caius.” – Brutus
“No, not an oath. If not the face of men,
The sufferance of our souls, the time’s abuse
If these be motives weak, break off betimes,” – Brutus
“Caesar, now be still: / I kill’d not thee with half so good a will,” – Brutus
“Not that I love Caesar less but that I loved Rome more.” – Brutus
