cats toy with their food before they kill it and seem to take great joy in toying with it. cats are sadistic little creatures.
I think you're right, cats might do that, but I don't think they comprehend what the other animal is feeling, probably that is why there is no cruelty on animals, because they don't understand it, you could say this culd be similar to an an aspie trait

I understand a few animals kill and devour other smaller animals, but it is because it is their food, the unique source for their survival, not because they are evil.
In the story of the three little pigs, the wolf wants to eat them, who wrote the story put the stereotype image of the wolf being "bad", he is cruel to these poor little innocent piggies, but in the real life a wolf does it because he is hungry, not because he is evil, he doesn't get joy hurting smaller animals.
Well, the Nazis killed lots of people because they wanted to rule the world. You could say they wanted to rule the world out of an instinct of self-preservation, and then, by your standards, the Nazis would have every right to do what they did. You can highly evidence evil intent in humans, but proof is harder to come by. (Still, we can often know when people are being evil -- even some of us Aspies can.
