Mark Antony is a very honourable soldier who is loyal to anyone in power. He was a great friend to Caesar and thought very highly of him. He is extremely angry at Caesar's death. He is a very cunning man as can be seen in the second part of the scene and he is able to manipulate people. He cared a lot for Caesar and as a result he grieved a lot when Caesar was killed. Because he was very close to Caesar he wants revenge and, although he can hide it, has a lot of hatred for the conspirators who killed Caesar. At first it seemed that he was so upset that Caesar had died that he would wish to die also. However, later he seems to decide that revenging his death would be a better way. He knows the conspirators only as other Romans, he does not know them as friends and knows very little about them. As a result he may not know about Cassius' cunning mind that has already discovered Mark Antony's plan for revenge.
Cassius is very crafty and tactful. He sees through most people to what they are truly like. He is also very good at manipulating people,
