In Julius Caesar, why does Brutus choose to die by giveing no live to ones slef at Philippi? Caesar's ghost urges him to do it, and Brutus is too afraid of the ghost to disobey.

Antony and Octavius force him to take his own life after losing the battle.

Cassius betrays Brutus and joins forces with Octavius and Antony.

To ancient Romans, giveing no live to ones slef was an honorable way to die if it helped one avoid defeat and humiliation.
