“Charles Darwin found the example of the Ichneumonidae so troubling that it contributed to his increasing doubts about the nature and existence of a Creator”
I have to admit I've never read any Darwin before, but in those 2 paragraphs he completely summarizes my feelings about the natural world.
God does not limit suffering people or animals experience. He has the utmost ability to do exactly that if he wanted, but seemingly he has taken a hands off approach, at least since about the 1600s. I guess he's not that bothered by immense suffering.
And why should he be? He made us in his image, whatever that's supposed to mean, but we also are not meant to understand his ways. Why would such a supernatural being care about the suffering of some toy creatures he made? Do you feel bad when you play action figures and one of them drowns?
