Perhaps when we look at the connection between animal cruelty and human violence, we would focus more attention on those who abuse animals to prevent them from escalating to crimes against people.
Given recent acts of heinous human violence in addition to the ongoing wars in which we're engaged, it's worth revisiting what we know about the social behavior of nonhuman animals (animals).
There has been a paradigmatic shift in our thinking away from vicious competition towards altruism, and this has been altering all human behavior, our nation, and our world.
