Caesar is a very high-ranking aristocrat, and although Krassu is a social slave, but has long been a slave owner + a businessman who is eager to be greedy, his political status is very low. Moreover, although Caesar swayed Krassu, the arrest of Krassu's son was Caesar's lack of evidence, and the last killing of Krassu's son was Krassu's own female slave. No matter from which point of view, there is no reason for Krassu to kill Caesar. What's more, human death can't be resurrected. For his own future, alliance with Caesar is only good and no harm, so it's okay to vent a slap, and tearing the face is not enough. What's more, Caesar is also a superior military commander. Before the annihilation of Spartacus, he would slap his own stupid things, and Krassu would not do it. The same is true of the subsequent historical development. After the Spartacus rebel army was annihilated, Krassu and Caesar returned to Rome, vacated the Senate, and became the "three heads" with Pompey, who did not appear in the play. alliance". In the later period, Krassu died on the outside, and Caesar triumphed in the civil war against Pompey (that is, the famous strategy: "playing on the face"), and Roman power was Caesar. In the Senate, the powerless aristocrats represented by Brutus, after planning for a long time, stabbed Caesar under the statue of Pompey before a deliberation.
