I don't agree. If humans needed to eat animals to survive then it might be reasonable to argue that killing animals for any reason other than food is wrong. Because then you could argue that you are inflicting the minimal possible amount of suffering.
But since humans don't need to eat animals, I don't see much difference ethnically between killing them because they taste good vs for no reason. If anything, that seems to be more about welfare of the human psyche than welfare of the animals.
