What inference can be drawn about Brutus's motivation and his character?

Brutus is ambitious for power of his own.

Brutus acts without thinking things through.

Brutus hates Caesar and is jealous of him.

Brutus seeks to protect Rome from tyranny.

The correct answer is Brutus seeks to protect Rome from tyranny. Brutus is a supporter of the republic who strongly believes in a government guided by the votes of senators. Brutus's inflexible sense of honor makes it easy for Caesar's enemies to manipulate him into believing that Caesar must die in order to preserve the republic. While the other conspirators act out of envy and rivalry, only Brutus truly believes that Caesar's death will benefit Rome. Torn between his loyalty to Caesar and his allegiance to the state, Brutus becomes the tragic hero of the play.

Brutus seeks to protect Rome from tyranny. This is the correct option. Brutus is an idealist and he loves Rome. He imagines Caesar will become a tyrant and this idea torments Brutus. Brutus thinks that tyranny will ruin Rome and her people.

These options are not right:

-Brutus is ambitious for power of his own. He wants to protect Rome against any evil.

-Brutus acts without thinking things through. In fact, he evaluates Cassius' words and he joins him in to kill Caesar. He thinks he will make Rome good.

-Brutus hates Caesar and is jealous of him. Brutus admires and honours Caesar but his love for Rome is much stronger.
