Tragedy of Julius Caesar

Betrayal and Honor-- Fearing that Caesar means to end the Roman republic and make himself the emperor, Brutus, Caesar's closest friend, allows himself to be caught up in a plot to kill Caesar. Once Caesar is killed Brutus realizes, too late, that there was far more to this than meets the eye. Let me have men about me that are fat; Sleek-headed men and such as sleep o' nights; Yond' Cassius has a lean and hungry look; He thinks too much: such men are dangerous.
