Extrajudicial use of capital punishment for hundreds of years.
Yup all those witch hunts, hangings, beheadings etc etc. All those killed off so many psychopaths and anti-social individuals. Ending their Genes right then and there.
Sure lots of innocent people got caught up in it all but far more often than not they killed bad people. Even if they were innocent they largely chose some one people hated, probably for good reason.
Yikes
so your theory is that European culture used capital punishment so much more often than Africa and Asia that it changed the gene pool forever?
😬🔫
Well the other option is to let the anti-social behaviors congregate into warlord tribes and spread their Gene's far and wide.
