If I recall, “Apache” was a name given the tribe by the
Navajo that means “killer” or “enemy” or something. I think
that they referred to themselves as something else.
I’m not saying they weren’t vicious. They were. Who isn’t when they’re constantly at war. The Apache were just better at it. There are many races no longer among us because they didn’t have the stomach to take it to a level that the enemy couldn’t accept. Any race still living did similiar things to the Apache.
