what are the characteristics of Cassius?

Caius Cassius is a man opposed to Caesar. He assembles the conspirators and is the man who convinces Brutus to kill Caesar. He commits suicide at the battle of Philippi after falsely thinking his army has been defeated.

Cassius is a very observent man; he has great foresight and in not easily deceived by those with false motives. His foresight, however, should not be seen in a positive light, as he regularly uses it to manipulate those around him.

Cassius is also jealous of the position Caesar has attained with the people of Rome, and envious of the power he has achieved. Note, although he manipulates Brutus extensively, he does become his loyal friend.
