The rules in the real jungle involve the big animal eating the little animal. Animals seem to accept this. But humans are expected to know better. Whether we realize it or not, most humans recognize the quality of greatness in another when we see that person demonstrating such respect.
Humans are very much like other animals in some fundamental ways.
We need to eat, sleep and keep the company of others. We have emotions. We get lonely. We snarl a little when we're irritated. Humans react to stress and abuse, just like other animals.
