Who were the former villains of history in common society?

by Zach_the_Quack

As of April 30th 2020, it will have been 75 years since Adolf Hitler committed suicide in his bunker in Berlin, thus marking an end to the Third Reich. In the aftermath, Nazi Germany and the man behind it have gone down in history as the most despicable people to have existed and have been immortalized as the pinnacle of human evil. Considering the fact that today (4/30/20) Hitler killed himself and marked an end to his reign of terror, I began to ask myself which other historical figures were somewhat equivalents of Hitler throughout various eras and places in human history. Or to rephrase the question, what historical figures were used as societal examples of evil incarnate? For example, was Attila the Hun or Hannibal the quintessential picture of evil for the Romans? Or in the mid 1800's was Napoleon considered to be the essential bloodthirsty conqueror by most Europeans? I know this is a broad question whose answer could wildly vary based on the time and place in question, but I would just like to hear maybe a few examples or so of what society considered the "former" pinnacles of evil. Thanks!

This is a commonly asked question here. There's a quick but effective answer by /u/davidlikespeace to that question more broadly here, while /u/kieslowskifan goes into more detail on perceptions of Napoleon and how they're a bit more complicated than perceptions of Hitler here, and /u/Georgy_K_Zhukov wrote about who Hitler got compared to at the time here.
