Mark Twain
Of all the creatures that were made, man is the most detestable. Of the entire brood he is the only one - the solitary one - that possesses malice. That is the basest of all instincts, passions, vices - the most hateful. He is the only creature that has pain for sport, knowing it to be pain. Also - in all the list he is the only creature that has a nasty mind.
