How does Brutus change throughout The Tragedy of Julius Caesar?My teacher told me that Brutus is a dynamic character, but he hasnt explained why. I...

At first, Brutus is a loyal friend to Caesar. The two of
them are very close. At the same time, Brutus loves Rome and he is a concerned citizen.
When Cassius plants the idea that Caesar is becoming overly ambitious, Brutus begins to
examine the situation. He begins changing his mind about
Caesar.

After Brutus decides to join the conspirators, he
becomes a murderer. He commits a violent act against his dear friend. After the
assassination, he insists that the conspirators wash their hands in Caesar's blood and
walk through the market-place. In this image, he appears to be a cold-blooded
murderer.

After Antony is permitted to speak as a memorial
to Caesar, Brutus has to flee for his life. He becomes despondent. His country is
plunged into a civil war. Portia commits suicide. Brutus loses his wife and becomes
hopeless.

He is angry with Cassius now. He was trying to
spare his country from  the slavery following Caesar's dictatorship. Although Caesar is
dead, Brutus sees his ghost and realizes that Caesar is still
ruling.

Because Antony's forces defeat him, Brutus falls on
his own sword. In a sense, Brutus has lost all the courage and bravery he once had. He
dies without hope of seeing Rome remain a free country.
