You lost the audience when you projected this statement "You believe that morality is arbitrary, that the means justifies the ends. I never said or implied that. Morality is a result of our brain's convergence due to evolution. It settles on what's best for the species survival, otherwise the species would die off. Sociopaths do not thrive. I can't say I know a single one of them personally. Natural selection would not permit sociopaths to survive [to dominate]. They would end up killing each other off. I do believe that behavioral therapy and medication can keep them in line sometimes. One form of behavioral therapy is religious indoctrination. You may now return to your original programming.
If there were a limited number per capita, as there is, they would thrive, as they have. Full blown sociopath is different than displaying sociopathic tendencies, which is basically a functioning sociopath, but we are getting off topic.

That's not arbitrary?
