There is a range in human behaviours. There may be a baseline, but not all are the same. And this is why theories that assume that everyone has a basic world outlook that is the same like you, that all people have a natural desire to be friendly, helpful, and sharing falter out of either a good nature or from a good maximizing, selflessly reasoning behaviour, falter so badly when applied to the real world. When a society fails to restrain some of the worst behaviours of those who prey on others in term of power or money, their example serves to bring out the worst in a much larger subset of the population that is marginally sociopathic, weak in their human values. Bad behaviour breeds bad behaviour, and those who profit by it find ways to justify this through self-serving social and political theories, to themselves and to others. And the pity is that people who have this variation in their character, either through nature or nutrure or both, as in the case of psychopaths and sociopaths, are naturally attracted to high profile positions of power. They tend to attract others like themselves, and create environments in which their parasitic tendencies and lust for power and money may flourish. And in its culmination can appear history's greatest tragedies, in which the madness that serves only itself without pity or remorse can be unleashed. Society is generally based on consumption, production, and cooperation. A system that has become tainted by the sickness of the disordered mind is based on debt, coercion and extraction.
