Yes, Brutus betrayed Ceaser. He was also his best friend. He organized a killing because he felt Ceaser was letting power get to his head and it was for the good of the country to remove him.
After this Marc Anthony led a revolution against Brutus and his counter-part (Cassius, i believe) and Brutus fled. As the toops were approacing, rather than become captive, he commanded his servant to hold out his sword as Brutus impaled himself upon it. I think this is what they mean at the end when they say "Time has come to do what's expected of you."
