Cassius chooses Brutus because, he is loved and respected by everyone in rome, including Caesar. Cassius is not liked because he is greedy and selfish. He kills Caesar because of jelousy. Brutus kills Caesar because he thought it would be best for rome. At Philippi Brutus and Cassius both commit suicide, because of honor. Antony says "<span>This (brutus) was the noblest Roman of them all: All the conspirators save only he Did that they did in envy of great Caesar;He only, in a general honest thought And common good to all, made one of them. His life was gentle, and the elements So mix'd in him that Nature might stand up And say to all the world 'This was a man!"
