Thank you for writing.
Actually, the Bible says that God clothed Adam and Eve, but there is no mention of any death. He could have used the shed skin of the serpent, much like the albatross that was hung around the neck of the mariner in The Rhyme of the Ancient Mariner, or made skins as He made everything else in creation.
The giving of flesh to eat was a concession because of the hardness of heart of the humans and was never God's creation or heavenly intent.
Jesus did call a number of fishermen to be His disciples, but He also turned them away from fishing to become fishers of men (to save mankind).
There is a huge difference between living as peacemaking children of God in His heavenly will, and justifying a life in this corrupted and fallen world.
You of all people must know that in order to take the life of another living being, we must first harden our hearts and souls so as to no longer have empathy for that being and their desire to live.
In the Love of the Lord,
Frank and Mary
