Why does the psychopath no longer need the group? Just like man in earlier times and the animal in the pack even today? Because he has a network of psychopaths who support themselves and psychopathize the world more and more. They hold man hostage in fear and force from him the resources they need. That is why the psychopath no longer needs a human being and yet does not perish, but, on the contrary, flourishes.
While the conscienceless, the soulless, the psychopaths were excluded in the clan and so they could not pass on their poison and their genes, they really live up in a lone wolf society. Poison them, multiply and manifest the madness as the new normal.
