There are two main ironies in the crowd's reaction to Brutus's speech. First, Brutus explains to the crowd that the only reason he killed Caesar was that Caesar was too ambitious. Brutus says he participated in murdering Caesar in order to keep from getting too much power.
"As he was valiant I honour him but as he was ambitious I slew him."
Brutus and Cassius delivered speech to convince the roman mob and give proper reasons for Caesar's death. Then Mark Antony delivered his funeral speech where he succeeded to influence the mindset of the fickle-minded mob in his favour. They began considering Julius Caesar to be the noblest man in Rome. They ran into rage against the conspirators. Brutus and Cassius were driven out of the Gates of Rome and Cinna the poet was killed when the mob punished him for a matching name with Cinna the Conspirator. The armies of 'Brutus and Cassius' and 'Antony and Octabius' geared to fight each other.
One example of how Brutus used the appeal of reason was wen he said that if Caesar was still alive then they would all be slaves and that they would all die as slaves if Caesar wasn't dead.
Brutus's purpose was to control the crowd as was Anthony's. Brutus began his speech with a hostile crowd against him as a murderer of the popular Julius Caesar.
Anthony tricks Brutus into letting him give a soliloquy at Caesar's funeral. He uses the opportunity to sarcastically implicate Brutus and Cassius in Caesar's murder. He says that Brutus considered Caesar "ambitious" using his speech to use Brutus' own words against him.
His reasons for speaking @ the funeral are to justify the conspirators' actions in murdering Caesar and also to introduce Marc Antony.
The crowd wants Brutus to take power and rule Rome
Brutus must read it first.
Mark Antony makes the speech of Julius' will. The will is not real, it was created by Antony himself.

Brutus's use of logos is exemplified in his speech to the Roman people, where he logically explains his reasons for assassinating Caesar based on the threat to the republic and his duty as a patriot. This rational argument appeals to the audience's reasoning and logic to justify his actions.
