The animal only goes into hatred in the moment of acute fear of death. Outside of that, it knows nothing of its imminent death.
Unlike the animal, the human being knows about his finiteness. That is why man in materialism, the man who cannot grasp eternity, is in constant hatred, in constant fear of death. He always has his inevitable end before his eyes and sees it coming every minute. That is why he always has to fight. Fighting against everything and everyone that presents itself to his eye. Using all means. And in his loneliness and in his futility, his turf knows no end.
