"Evil is a logical foundation for morality which is a highly evolved sense of self and other that occurs in homo sapiens. ..." Sab,above
NO it's not!! The concept of "evil", tends to be a theological self-serving label slapped onto anything that theists perceive as "wrong" - or threatening to their theological worldview - just as many of them view same-sex marriages, pregnancy out-of-wedlock, empowerment of women, freedom for slaves, etc, as "evil" - until the masses move past the theologists, and they have to play "catch-up"....
As "tornapart" said, bottom of page 1:
"Maybe you should see things from the tetse fly's point of view.. I'm sure he's quite happy with things....."
Tsetse flies, being another species that evolved on this planet, same as the rest of us, are self-justifying - they evolved, they exist, and any harm/calamities that they cause, well, that's something for the OTHER species to EVOLVE defenses against!!
And THAT dance - evolve an effective predatory/parasitic behavior, then the prey/hosts evolve defenses against it, then the predators/parasites evolve ANOTHER effective behavior, then the prey/hosts evolve ANOTHER defense against it...
THAT is the reason one sees a sort of "arms race" in the paleontological record... And in our modern-day world, too.
