I once read a book on primatology (can't remember the title, wish I could) that observed that over 8 million people live together in NYC. For the most part peacefully. But if you put 8 million chimpanzees together in the same space they would rip each other apart. It would be a bloodbath.

Which is to say that one of the unique things about humans is our ability to get along with each other. To form ever-larger stable communities. So I question your declaration that the "true nature of humanity" is to be in competition with one another. I'd say we're the dominant species on the planet precisely because we have an ability to put aside competition and cooperate with each other. Not always, of course, but the majority of the time.
