When is it wrong to kill animals anymore?

[BennyJackdaw]

I see so much pushing towards hunting and killing, whether it be killing deer for being overpopulated or even killing endangered species with the idea that money raised from it will help them, or even when cats and dogs get spayed or neutered, which isn't killing any existing animals, but will stop those from being born. It feels like, these days, the only time it's wrong to kill an animal is if that animal is a human.

I just want another sign. When is it absolutely wrong to kill a non-human animal?
