The Greeks and Romans, for example, don’t seem to have been run down by psychopaths.
With genocide of any foreigners and mass torture for entertainment also having been considered perfectly acceptable, the Roman culture in the flesh would certainly feel alien enough to us that an utilitarian, altruistic time traveler could likely be predicted to attempt to sway it, with virtually any means justifying the end for them.*
I know I would, and I know that I’m not an unusual decision maker for the LW community.
*(cue obvious SF story idea with the time traveler ending up as Jesus)
But these seem to have been larger cultural phenomena, not the unchecked actions of a few psychopaths. Psychopathy affects around 1% of the population, and I doubt so few people could have swayed the entire culture if the rest of them had no interest in killing people.
You’re right that we don’t have data on the incidence of psychopathy in ancient Rome, and our data its current incidence is pretty sketchy. (Unlike most mental illnesses, psychopathy is more a problem for other people than the person who has it, so psychopaths have no reason to get treatment. Not that we really have any treatment if they did.)
But there seem to be both genetic and social components (e.g. being abused as a child), so probably those same genetic opportunities got triggered in some people throughout history. Possibly at different rates than here and now.

One percent of the modern population. How much historical data is there?
