Our ancestors who evolved to hunt did not "play fair", they killed animals any way they possibly could. Running them off cliffs, into pits, setting fire to the forest to burn them alive. Might as well say guns and knives aren't hunting, that you have to use your bare feet and hands and that's it.
Our ancestors, although containing the equivalent or even greater intelligence as us, were unlikely to consider morality or ethics when it came to survival.
Both comments above sounding much like Victorian era post Darwinian drawing room expressions of "Nature red in tooth and claw" and other aphorisms not sourced to either Darwin or Wallace, all running contrary to the actual considerations of actual hunter and gathers (Pintupi Nine, San Bushmen, etc) who repeatedly stress the importance of not killing off your food supply by over taxing breeding and regrowth abilities.
I'm not entirely sure what you're referring to regarding my comment, which was effectively addressing the non-comparative examples of hunter-gatherers killing for pure survival versus modern humans killing out of annoyance or so-called sport, where food is just around the corner, except in extreme cases of poverty and such.
It's also not clear whether the last bit of your comment is entirely accurate. Is there not plenty of evidence of ancient humans overhunting fauna? That was my understanding and a quick search seems to verify that.
Ah, the deep-seated caveman urge to hunt down utility poles, shoot the electricity out of your neighbors, I mean, enemies, and hear the lament of their melted ice cream ...
What you are describing is sadism and/or mental illness.
