Even carnivores in the wild don't tend to kill like we do. It's risky to get into a fight and takes energy. They usually do it to eat enough calories to survive.

Humans kill for aesthetically pleasing materials, to affirm gender identity, to eat for pleasure (to the extent that it's detrimental to health and we put effort in to prevent that! Sometimes killing more to produce or test medicines to treat the problems created by the recreational eating we do).

It's pretty ridiculous however you cut it.
