What troubles Cassius about Caesar?

Answer 1

Cassius, like the other opponents of Caesar, who wanted to defend the Roman Republic were worried about suspicions, probably justified, that Caesar was trying to become a king. This was anathema to Republican culture. The Republic had been established in some 460 years earlier with the overthrow of the last king of Rome who was a tyrant. The Romans decided to do away with the monarchy and to establish a Republic headed by two annually elected consuls. The aim of the Republic had been not to leave power in the hands of a sole man so as to prevent the return of tyranny. The Romans also swore that they would not allow anyone to become a king ever again. They associated monarchy with tyranny. In the Early Republic trying to become a king had been the worst allegation against anyone. In the 5th century BC a man was killed and his house razed to the ground because he was accused of trying to become a king and in the 4th century BC another man was executed for the same reason.
