In The Tragedy of Julius Caesar by William Shakespeare, there are several examples of leadership.
Cassius, a shrewd general of the Romans, leads Brutus to believe that Caesar is too powerful and must die for his ambition. Leading Caesar into the hands of the conspirators, Decius provides another example of leadership. Antony even leads the audience at Caesar's funeral to turn against the conspiritors.
Any ability can be used in a good or bad way. As a weapon, leadership can be used to right a wrong, or to save lives. It can also be used to take them away. Using leadership, the characters in the play displayed this fact acutely.
