What is the difference between between Octavius and Antony?

Antony, Octavius and Lepidus differ significantly from the original conspirators. They wish only to avenge Caesar's death and are willing to murder each of them, stating "These many, then, shall die; their names are pricked" (4.1.1). In their counter-conspiracy, they are willing to include relatives and friends on the list of those to die, demonstrating they are most serious and dedicated to the task of eradicating those who conspired against Caesar. Antony's statement, "He shall not live. Look, with a spot I damn him" (4.1.6) brings to the forefront the calculating nature of the new rulers.

Antony then sends Lepidus to Caesar's house to fetch the will. He hopes to somehow reduce the amount of money that needs to be paid to the beneficiaries. After Lepidus leaves, Antony tells Octavius that Lepidus was a poor choice to form the second triumvirate with. Octavius says, "You may do your will; / But he's a tried and valiant soldier" (4.1.28). Antony implies in his speech that he will eventually remove Lepidus from rule, but that they should keep him a while longer.
