This is tangential, but what you wrote about nature reminded me of a biology professor once saying how at least in nature it seems like other animals generally kill in a quick, efficient way where hopefully the prey won’t suffer too much.

Humans are by far the most vicious animal species, because the sophistication with which they apply torture is off-the-charts. Felines and orcas may consume their prey alive or play with them, but it's not in their capacity to keep their victims alive indefinitely with the express goal of inflicting maximum suffering.
