Consider that there are all these that are shown in the Bible (there really are yet more things in the Bible for it with better understanding).
Proverbs 12:10 should not be ignored. And nothing one would eat should be prepared with having blood in it.
Psalm 50:9-11
God has no need for animals to be killed.
Genesis 1:29, Genesis 2:19, Genesis 6:5-8, Genesis 8:15-17, 20, Genesis 9:1-5, Acts 15:22, 28-29, Romans 8:19, 21-22, Isaiah 11:6-9, Revelation 21:4
God said, "I have given you every herb that yields seed which is on the face of the earth, and every tree whose fruit yields seed, to you it shall be for food." Yahweh God said "It is not good that man should live alone." Out of the ground Yahweh God formed every beast of the field and every bird of the air, and brought them to Adam to see what he would call them. Then Yahweh saw that the wickedness of man was great in the earth, and that every intent of the thoughts of his heart was only evil continually. So Yahweh said, "I will destroy man who I have created from the face of the earth, both man and beast, creeping thing and birds of the air." But Noah found grace in the eyes of Yahweh. Then God spoke to Noah, saying, "Go out of the ark, you, your wife, your sons and their wives. Bring out with you every living thing of all flesh that is with you, that they may abound on the earth, and be fruitful and multiply on the earth." Then Noah built an altar to Yahweh, and offered burnt offerings. God blessed Noah and his sons, and said, "The fear of you and the dread of you shall be on every beast of the earth, on every bird of the air, on all that move on the earth, and all the fish of the sea. Every moving thing that lives shall be food for you, I have given you all things, even as the green herbs. But you shall not eat flesh with its blood. For your lifeblood I will require a reckoning." It pleased the apostles and elders with the whole church, to send chosen men of their company to Antioch with Paul and Barnabas. They wrote this letter: "It seemed good to the Holy Spirit and to us to lay upon you no greater burden than these necessary things, that you abstain from things offered to idols, from blood, from what was strangled, and from sexual immorality. Keep yourselves from these, you will do well." The earnest expectation of the creation eagerly waits for the revealing of the sons of God. For the creation was subjected to futility, not willingly, but because of him who subjected it in hope, because the creation itself will also be delivered from the bondage of corruption into the glorious liberty of the children of God. For the whole creation groans and labors with birth pangs together until now. "The wolf shall dwell with the lamb, the leopard shall lie down with the young goat, the calf and the young lion and the fatling together, and a little child shall lead them. The cow and the bear shall graze, their young ones shall lie down together, and the lion shall eat straw like the ox. The nursing child shall play by the cobra's hole, and the weaned child shall put his hand in the viper's den. They shall not hurt or destroy in all my holy mountain, for the earth shall be full of the knowledge of Yahweh, as the waters cover the sea." "God will wipe away every tear, there shall be no more death, nor sorrow, nor crying. There shall be no more pain, for the former things have passed away."
