I think you may have shifted the goal a bit. Your first statement seemed to be a sweeping characterisation of their objective place in that universe. Your follow up statement is now more a human endemic point of view.
Also, I’d point out that your supporting examples for your logic argument are direct appeals to emotion.
In my opinion, if examining the food chain logically, those higher on it eat those who are lower. There is no value judgement for choosing to live by eating. The value judgment only enters on how you do it and *that* is where empathy and sympathy live and only because we’ve evolved these systems likely as part of a species survival mechanism (as all mammals and many other species). The concept of “evil” itself is just a mirror back to these chemical reactions in our brains as our developed minds attempt to find patterns and meaning when these evolved mechanisms and our ability to interpret them exceeded the initial design. Hydrogen has no such hangups.
And, no judgement there. Personally, I think we’re captives to our chemical reactions and the emotions they cause combined with socialisation, circumstances, et cetera. I don’t even think we have free will as we think of it, but that’s another topic.
As for your neighbour, have you ever considered a pet tiger? I hear they have fearful symmetry. Our cat might help, too. She’s on an allergy diet for two months and her canned food’s main ingredient is potato peels so she’s craving meat. She now wakes me daily at 4.00, 4.30, 5.00 and so to loudly complain about the lack of chicken on her plate.
