And, quite seriously, the existence of this type of horrific parasitism precludes the existence of any sort of benevolent god in my mind. It's easy to imagine a million different universes where this sort of abysmal torture doesn't exist, and it only makes sense in the view of "uncaring" evolution.
If you were to ascend to the heavens and obtain dominion over all of the universe, would you spend your time meandering around the cosmos, exterminating species whose lifecycles struck you as "horrific"? Would this behavior make you more moral than a god who simply permitted nature to take its course?
This makes no sense to me. Doesn't pretty much every major religion believe God created nature in the first place? Yes, if I were God, I would create a nature in which the horrific torture of innocent, sentient creatures was not possible. On the contrary, currently nature requires this horrific torture for creatures (the parasites) to simply survive in the first place.
Stephen Fry puts it better than I ever could: https://www.youtube.com/watch?v=-suvkwNYSQo
Keep in mind that any negatives you permit will be offered as proof against your benevolence.
But that's why the torture of this parasitoidism is so clear cut. I can't imagine any sane person thinking that this kind of torture is anything but pain and evil. Fry's example is a great one "The world has it in insects whose whole life cycle is to borrow into the eyes of children and make them blind that eat outwards from the eyes. Why? Why would you do that to us? You could have easily have made a creation which that didn't exist." If any person created that kind of torture device we'd consider them to be one of the evil-personified villains in a comic book novel. But yet we come up with all these ridiculous explanations about how a benevolent god created that, just for shits and giggles?
What impresses me the most is that the wasps are not trained to do that. They appear to "just know" what to do. Wow.
