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.
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 ...
