While we share much in common with the animals there are fundamental ways in which there is no comparison. Our ability to love, to think, to communicate, to dream, to plan, and to create send our species soaring high above any other form of earthly life. Yet the reach of our capacities is matched by the depth of our perversities. Sometimes when people do especially vicious things we deride them as animalistic. Truly, that is unfair to the animal kingdom.
Human evil is far worse.
We make use of our unique capacities and invert them for evil. We have found a nearly infinite number of ways not just to kill each other but to torture our victims first. We can organize evil on an unimaginably vast scale, such as the development of gruesome military weaponry and the unleashing of government-sponsored genocide. We use our amazing linguistic capacities to craft verbal swords and bullets to wound not only those we hate but also those we love. We make promises to each other but then baldly break them.
