Marcus Porcius, thank you for your reply. I've always thought that the system of governing the provinces endeared hatred for Rome, especially characters like Verres. It seems that getting rich of one's province through extortion was too great a reward for being elected consul or praetor, and no one was willing to do anything about it, as it was accepted custom.
You also raise a good point about a general's armies belonging to the general and not to Rome. Marius, Sulla, Pompey, Caesar all led armies loyal to them first and to Rome second. Perhaps if the legionaries had to swear an oath to Rome first and their commander second that could have been abrogated.
