How many serial killers were ever spawned living in a tribal society?

Plenty! Tribes often went to war with each other and they'd kill one after another after another. That's called serial killing, kid. It doesn't do to romanticize primitive people; it can even get you killed. And we all at least started out that way. Some have managed to come farther from that beginning than others.

No one talks about it, but that doesn't mean it doesn't happen.

If a bear shits int he woods, and you can't hear it, does it mean it doesn't happen?

BTW, Look up Hutus and tsutsis.

There was this tribe called Aztecs...........

but all tribal societies lived in peace and picked flowers, traded sea shells and sang Kumbaya around a camp fire....didnt they?

Of course you won't think of one.

The question is an oxymoron.

When an ENTIRE tribe is mass murderers why worry about what they spawn, unless it was someone with a conscience?

Head hunters and head scalpers were doing what the ENTIRE tribe would have done, ALL spawned were mass murderers...

Huron, Chichimec , Iroquois and Muskhogean tribes all scalped their enemies.

Additionally, China, Nigeria, Nuristan, Myanmar, Borneo, Indonesia, the Philippines, Taiwan, Japan, Micronesia, Melanesia, New Zealand, and the Amazon Basin, as well as among certain tribes of the Celts and Scythians of ancient Europe, all practiced head hunting.

That's twenty, want more on other occasions, or what?

You know what really grossed me out, that I heard about the Chichimecas? On their trips, on long treks across the desert in northern Mexico, they'd carry dried meat on their belts and guess what it was: human babies. Their own human babies, if they already had enough or it was inconvenient or who the hell knows why. Baby jerky. Yuck.

Then there was a story about some cooking contest, I think it was in Australia: this was just back in the 1980's: a guy from New Guinea entered it and won with: you guessed it, 'baby back ribs.' This was (supposedly) a real news story. There was some consternation when the judges realized there was something wrong with that meat.

Tamerlane.

That's one.
