Cicero said after the assasination that it was a good dead but one half done.

By this he meant the assasins should also have killed Mark Anthony whom Cicero correctly believed would take the reigns of power after Caesar's death. Cicero constantly criticised the abuses of power being comitted by Mark Anthony in his Philippics, although he actively supported the rise to power of Octavian because he believed that Octavian could be manipulated by himself. However when Anthony proscribed Cicero, Octavian did nothing.
