The tendency clearly facilitates group cooperation for the benefit of members. In this respect, it mimics much genetic programming of social insects.
We see the extreme power of the tendency to reciprocate disfavors in some wars, wherein it increases hatred to a level causing very brutal conduct. For long stretches in many wars, no prisoners were taken; the only acceptable enemy being a dead one. And sometimes that was not enough, as in the case of Genghis Khan, who was not satisfied with corpses. He insisted on them being hacked into pieces.

What both human and ant history suggest is that
