Why do brutus and Cassius kill themselves?

Answer 1

Brutus asks Strato to kill him so Brutus wouldn't have to die by the enemies sword

*<edit>

Because the last answer was rather strange I decided to help. Cassius killed himself once he thought his friend (Titinius or something like that) was kidnapped by the enemy. He asked Pindarus (or how ever you spell his name) to kill him. Brutus kills himself later (thanks to the help of Strato) cause he's sure they're are going to lose to Antony. That's how it works in the play Julius Caesar but for all I know the top answer could be true. I rarely look into things deep.

2nd edit

brutus kills himself because he feels bad for killing Caesar for no good reason. Cassius kills himself b/c he thought titunius was kidnapped and dead.

after all this, Antony, octavius and lepidus are in charge of rome

Answer 2

Why do Cassius and Brutus take their own lives at the end
