Unicorn, as you try to sound smarter than everyone else, you prove yourself to be even more crazy than previously thought. Let me give you an example by quoting your signature:
"How we use our free-will, determines our eternal destiny in Heaven or Hell."
Are you saying that your choosing (free-will) to kill all the animal examples listed by Steve is going put you on your holy road to Heaven??? If not, how exactly does that fit into your great plan?? How do you think those animals got here to begin with, and who are you to eliminate them? By the way, how do you propose to teach a lion to "refuse to stop killing weaker animals"? Have you ever heard of the food chain? You call yourself a member of PETA? I hate that organization, but I've never heard of them wanting to eliminate certain species? What are you, a specieist (your word)?
Why do people incist on going all vegetarian when the history of mankind, all the the way back to the ancient cavemen ate meat? The problem is not about eating meat altogether, it's about how much meat you eat. It's about balancing your diet: Meat, Poultry, Fish, Grains, Vegetables, Fruits, etc... Get it?
