But these are the most human questions in the world. Man has been asking them since the dawn of time, universally. It's almost as if man had been "programmed" to ask them....
But you exempt yourself from "that sort of thing." Why?
I've watched my cats for years and noticed that they are just like little humans. They'll take food from each other if they can. They'll pick on each other sometimes just out of boredom. They're mean to each other when they are strangers, but if they develop affection, it lessens. Adult cats will attack strange kittens. Cats will kill small rodents for fun even if they are not hungry. It goes on and on, this is just how creatures are. Even trees crowd out smaller trees and hog the sunlight. Parasitic organisms feast on their hosts even unto death. It's just the nature of creatures trying to survive, and the more advanced ones trying to attain pleasure.
