In OTL, when we think of evil in history, the first thing that tend to come to mind are Hitler and the Nazis -- as such, they've become our go-to image of society gone wrong, of human capacity for bad, and what have you.
What I'm interested in -- take an ATL (only restriction -- no Nazi Germany; can be anything*); what is the equivalent go-to evil in their society's historical consciousness? Can be an OTL from before PoD or AH...
(Also, this may have been done before -- if anyone finds it, can you post the link?)
*please ignore forum -- PoD can be before or after 1900
