Wild animals must be free from violence? Has this guy seen how a fox kills a rabbit? Or how a coyote kills a fox? Or how a bear kills an elk?
Many species of wild animals live by inflicting violence on other wild animals. It’s their job.
EVERY animal & plant in nature is part of the food chain.
You will potentially be eaten by anything that is larger, faster or smarter than you.
Just like the stories of some old lady dying in an apartment. Then they find her a week or two later and her dog or cat has started to eat her.
Or a lion, wolf or tiger kills an antelope or deer, for that matter.
They DO want donkeys to kill elephants.
