I think its unfortunate that opposition to torturing animals is often lumped in with opposition to merely killing animals.
He said that these cows have exactly one bad day in their lives, as they spend their entire lives with their mothers in grassy pastures.
The nature of torture aside, taking the life of a sentient being is the ultimate violation of its rights. I don't see how any act less than killing can be considered morally worse than killing.
This does not make it right for a human to deliberately cause harm to an animal for pleasure or entertainment. I also would consider trophy hunting to be immoral if one leaves the body to rot.
Why?
They are different things that inflict a different amount of suffering and distress on a creature capable of feeling suffering and distress.
