I remember hearing a fellow talking about the Nazi doctors on the radio. He described these people as monsters, subhuman. It's true, of course, that we human beings have done monstrous things. But none of is anything other than human. Indeed, it's because we're human that we are capable of such monstrous actions. If we don't realize this--that every sadistic murderer is human, like us--then we overlook the fact that we have the capacity to act as they do.

We have to realise what we are. That range of what is human is vast, ranging from the saintly to the monstrous. When we speak of other human beings as if they somehow do not belong to our species, we ignore the reality of our very nature.
