"So if the killing of animals is wrong why has the 'creator' designed them to kill each other to survive? A wild cat is never going to eat a salad.."
Here is my reply:
I don't know understand your argument.
Why do you think that evolution is a deterministic process controlled by a Creator?
Cats are also killing for pure enjoyment, just like many humans do. Do you think this is morally justified? Do you think that this is a behavior that a Creator put into the cat – to kill other beings for enjoyment?
Some species evolved to become meat eaters because of that they lived in areas with a scarcity of plant based foods, and that their genetic mutations combined with them choosing to kill other sentient beings, increased their survival rate.
That they got genetic adaptations for a certain behavior, doesn't morally justify their behavior.
As I asked,
Do you think that cannibalism is morally justified?
I argue that we are not morally justified to kill either humans, or other animals for our survival. See this blog post that I have written:
Furthermore, as I said before, humans today in our culture are not killing for survival, we are killing for “pleasure” or convenience – for a trivial “taste experience”.
I agree with these quotes by Leo Tolstoy:
“A man can live and be healthy without killing animals for food; therefore, if he eats meat, he participates in taking animal life for the sake of his appetite. And to act so is immoral.”
“Thou shalt not kill” does not apply to murder of one’s own kind only, but to all living beings; and this Commandment was inscribed in the human breast long before it was proclaimed from Sinai.”
