Throughout the play, Brutus speaks of honor and his loyalty to his country. These two concepts become major conflicts for him when it comes to his friendship and loyalty to Caesar. Brutus' life is led by the concept of honor. Throughout the play he constantly talks about how honorable he is and how honorable men should live. He is very proud of how the Romans see him as a noble and honorable man, who fights for what is right and always follows the moral and ethical code. Brutus ends up using the concept of honor and loyalty to his country as the reason why Caesar must die. He is convinced that his countrymen will thank him for saving them from a tyrant and that Rome would be much better off without Caesar, but it ends up being a huge miscalculation. His honor and loyalty shape the world around him. You can see how honor and loyalty have shaped the world around him when Cassius comes to him for help in dealing with Caesar. You too Brutus love Caesar and know that Caesar is a good man, let Cassius convince him to look deeper and see that Rome cannot have a tyrant as a leader. He says to Cassius "Into what dangers would you lead me, Cassius, that you would have me seek in myself, that which is not in me?" (1.2.65-67). Brutus knows that killing his best friend is not something he wants to do, but he is willing to commit such a crime because it is for the good of Rome and the people of Rome. If that friend then asks why Brutus rebelled against Caesar, this is my answer: not that I loved Caesar less, but that I loved Rome more." (3.2.19-24). His focus on honor and on the nobility ends up being used against him by Cassius, who instigates him to kill his best friend Cassius knows how naive and moral Brutus is and uses this information to help him kill Caesar. Being naive and overly trusting causes his first mistake and helps with his downfall when he refuses to listen to Cassius, who wants Antony killed as well because he knows he will seek revenge for Caesar. However, Brutus' code of honor will not allow him to approve the. killing Antony "Our plan will seem too bloody, Gaius Cassius. We cut off the head and then we cut off the limbs, it seems that we kill Caesar in anger and then vent the malice on his friends, because Antony is only a branch of Caesar." (2.1.169-172), he does not want to be seen by the Roman people as a murderer, but someone who does what is right for the people
