There’s nothing natural about being slaughtered against your will.
this assumes non-human animals have a will to live. this would require an understanding that they, themselves, might die. we have no proof of understanding personal mortality in non-human animals (though, if you have a study that shows otherwise, i would be very interested to see it). therefore, we have no reason to believe nonhuman animals have a will to live.
no, and it's also not the cause of death for any of the animals we eat or otherwise exploit.
