Yes, I'm sure I don't want any long-term dictators. Caesar can be a powerful senator/consul/general, but my aim is to not let Pompey and Caesar be Sulla & Marius 2.0.
Pretty sure that battle is already more or less lost since at this point in time the political system as well as culture is more or less perfectly suited for exactly that kind of strongmen and I honestly see little way to reform it without becoming one yourself. Realistically if it weren't Caesar and Pompey you would get another bunch of ambitious and successful generals doing something like this because the circumstances make it nearly impossible to avoid it.
Yes, because the worse the dictators are, the more backlash they will generate. the smart ones and able ones will be very hard to dislodge and then you'd have to contend with their imitators.
If you have a disastrous one or two? then you can cast them in the same light as the roman kings.
Yeah, I am sure that the theory of Accelerationism will be the perfect consultation to us when said disastrous dictators burn Rome and us down and surely such a person will serve as the perfect example and warning to the Roman people like Sulla, Marius or the Gracchi (and many others) did.
