I would observe that eating meat was a concession on God’s part, but not part of original creation order.
In the garden, Adam and Eve (and all the other animals for that matter) were allowed to eat any plant.
Behold, I have given you every plant yielding seed that is on the face of all the earth, and every tree with seed in its fruit. You shall have them for food. And to every beast of the earth and to every bird of the heavens and to everything that creeps on the earth, everything that has the breath of life, I have given every green plant for food.
Animals were allowed to be killed for sacrifice purposes, and presumably God killed the first animals to provide garments of skin for Adam and Eve.
It was not until after the flood that God gave authorization to eat animals (presumably, at least in part, since it would have destroyed so much vegetation).
Every moving thing that lives shall be food for you. And as I gave you the green plants, I give you everything.
Thus I suspect that this temporary provision will cease when all things are made new, and there will be no more death. Until that time, we operate in the present word where death is a reality.
I’d ask 2 questions back at you, if I may.
Your concern seems to be with honoring animals and them avoiding pain, etc. just to understand your position, would you object to a system where we ate the same animals we do now, so long as we only collected and processed the meat of said animals after they died of natural causes?
if you are embracing an evolutionary perspective on these things… We got to where we are through being carnivores. Why stop now? I would think “our shared relationship in the evolutionary saga” makes killing another animal for food simply a continuation and participation in the same thing life has been doing for eons, no? It still seems to work for lions and tigers, why stop now?
