You can do everything right and still get the ax
Pleasant imagery, right? No Roman illustrates this point better than Emperor Aurelian. To summarize his plight, Aurelian inherited an empire that was in absolute shambles: Rome was in the middle of a century of misfortune and the empire had lost two huge chunks of territory known as the Gallic and Palmyrene Empires. At the time, it looked like Rome might be heading for a fatal balkanization when Aurelian stepped in. Not only did he save the empire from Germanic invaders on multiple occasions, he also reunited and stabilized the empire, all within 5 years! And what was this savior's reward? Getting stabbed by a cabal of his closest generals! One could also draw an analogy to the endeavors of Pyrrhus of Epirus, the celebrated Greek general who constantly beat the Romans but still lost his war, and from whom we have get the eponymous notion of "Pyrrhic victory."
If you listen to contemporary rhetoric, you'd believe modern Americans are the sue-happiest people in the history of the world. If you believe that, I guess that's another reason you should be happy you weren't born into the Roman empire. In his 88th episode podcast—A Day in the Life— Mr. Duncan explains that the ". . . famously litigious Roman's . . . sued the bejeezus out of each other." It's about 10 minutes into the podcast if you want to listen to that specific section. The Roman laws also begot to us the adjective "byzantine," to describe something inflexible or overly-complex, like their laws.
While it's undeniable that high-profile [probably] frivolous lawsuits occur, I'm in the group that thinks litigiousness is more of a mark of national stability than anything else. If one doesn't believe that the legal system will, on average, correctly settle one's affairs, than one is more likely to utilize extralegal means to achieve one's goals. The fact that Romans (and Americans) would turn to their court systems so frequently shows faith in said systems as the best means of settling a dispute. In most cases, it's preferable to a duel to determine who is at fault for your car accident. Either way, I think a trustworthy legal system was a major factor in the longevity and (relative) stability of Roman hegemony in the Mediterranean (and afterwards in the Byzantine Empire).
