What is your opinion on the Roman senator Cicero?

Many people seem to have a favorable opinion of him, for supposedly defending the Roman republic during its collapse, but seeing his history and actions he did everything to defend the interests of the Roman elite to the detriment of the Roman population, and abused the system against their enemies when it was convenient and was a landowner famous for building the buildings in a horrible shape. Still, it has a reputation for having defenders to this day.
