There's just too much of it.
Of course it is biologically necessary, but often we would get the message that there is something dreadfully wrong happening to our soft tissue/bones/organs from much less.
There is no need for quite so much of it.
I don't know what the theological implication is. "Curse God and die!" they said to Job. Hahaha! It's not that easy. I tried.
God indeed. I don't think there is a God, yet. I think that's what this is all about, this brutal struggle of life: we are building God, but he's not ready yet. The blood sacrifice of millions of generations of shocking pain, the blood shed by evolution.
One day the benevolent and incandescent one will rise.
