To find the answer, one must look to the animal world. Predators are small in number but strong, well equipped and highly aggressive, they survive on Preys.  On the other hand, Preys are in huge number, they are Tame, Cowardly and only fight among themselves. The only safety net they have is NUMBER, safety in Number.
Human are basically animal with moral value.
Culture makes you Predator or Prey.
Ironically, Preys survive longer.
