Well, the Bible is filled with numerous specific examples of faithful servants of God eating meat with no implication that they did wrong.
Genesis 25:27,28; 27:1-4 - Esau was a skillful hunter. His father Isaac loved Esau because he ate what Esau killed.
Genesis 43:16 - Joseph had an animal slaughtered for his brothers to eat with him.
1 Samuel 25:18 - Abigail brought sheep dressed to eat as a gift to David and his men.
1 Kings 4:22,23 - Solomon, the wisest man who ever lived, ate oxen, sheep, deer, gazelles, roebucks, and fowl.
1 Kings 19:21 - Elisha slaughtered oxen to feed people.
1 Chronicles 12:39,40 - David and the people ate oxen and sheep when he was named king.
Nehemiah 5:17,18 - Nehemiah provided for those who ate with him oxen, sheep, and fowl.
Matthew 3:4 - John the Baptist ate locusts and wild honey.
Note that many of the people ate, not just fish or birds, but "red meat": cattle, sheep, oxen, etc.
If eating meat is immoral, then all these people were immoral and sinned in eating meat. Yet the Bible presents them as good people and never once implies they did anything wrong in these cases.
I'm not trying to make this a religious discussion, but if you are going to talk about evil and immoral behavior, I guess that would mean many Biblical figureheads were bad in your eyes.
It's not one of the 7 deadly sins and it's not one of the 10 commandments. I don't see a "thou shalt not eat meat". So, I'll continue to do so. And, yes, I do know how cows are slaughtered. It's not nice, but it's better than how it used to be.
