Why does Antony shake hands with the conspirators?

Antony shakes hands with the conspirators to make them believe that he does not have ill intentions toward them. He ultimately desires to take a brutal revenge against the group, but he is aware that confronting them directly after Caesar’s murder would likely prove fatal for him. Showing great wisdom, inner resolve, and patience, Antony “makes nice” with the conspirators and relies on his unassuming reputation in order to bide his time, turn the people against the conspirators, and raise an army to enact his revenge against them.
