A big part of the portrayal of Ca**ius has a lot to do with political and personal beliefs. A lot of things in the story is about personal stuff.
The conspirator agrees to k** Caesar anyone else close to him but Brutus disagreed. Brutus did not want to k** anyone else because that would not be right. There is no need to cut off Caesars arms and legs. Murdering Caesar would be enough. Brutus wants the murder to appear justified as being good. Brutus is just as guilty as everybody else. Even though he claims to Julius Caesar best friend, he still k**ed him. The plot to k** Julius Caesar is brutal and was planned by a group of his companions.
Marc Antony was a good friend of Julius Caesar and kind of took over after he died. Marc Antony fought Brutus and fought to become ruler of the Roman Empire. I think they could have compromised and not fought so much. They could have shared power in the government. After Brutus k**ed Julius Caesar, Marc Antony convinced the whole crowd that Brutus was wrong and Julius Caesar was a good leader and man. Marc Antony was right, Julius Caesar was a good friend. Brutus is cruel and he is easily influenced.
Marc Antony won the war and Brutus and Ca**ius took the easy way out and k**ed themselves.Now Marc Antony is fighting the people that was with him because they don't want to share power.
