Supercolonies and Psychopathy

At first sight it would appear that psychopaths should be everywhere. How on earth could evolutionary pressures prevent the creation of psychopaths in human civilization when it appears to actually favour them? Why don't all species eventually collapse because of these parasitic agents (whether it be within the specie or external to it).

The fact is, humans are a poor example of how nature removes parasites because modern human society does not mimic how it was evolved in order to control for parasites.

The selective pressures against a parasite are weakest in supercolonies because of the absence of internal competition. In the human body (a supercolony of cells) the immune system exists to allow for a reduced risk of parasitism within the body through the use of an authority system. There is a cost to this however, errors in the authority class can cause mass havoc, in this example, autoimmune disorders.

Supercolonies without a functioning immune system eventually are wiped out by parasitism, shrinking the natural size of the population to a level that can manage parasitism through isolation and competition (natural forces that keep parasitism at bay).

Two factors that prevent colony collapse in humans is not the lack of parasites, but because of human cognition and the speed of growth of our supercolony. Both prevent collapse but in different ways. Conscious awareness incentivizes the parasite not to over consume to the point of collapse, so in this case, compromise (i.e. longer term management of theft) prevents the parasite from killing the host. In nature (i.e. nonhumans/nonconscious beings) this compromise still happens, just not through cognition. The other factor, growth, if greater than the negative effects of parasitism, can create a net growth for the colony even if parasitism is also growing (be it viral/external or cancerous/internal). In this case the supercolony itself may turn to parasitism of the external environment to maintain this growth (because the colony is forced to grow or die, due to the parasitism). 

It is important to note that these effects do not work by selecting against the parasite; in one case the parasitism is optimized for the parasite, not the colony (if benefits result to the colony, they are by chance alone), and in the other case the parasite is actually being fed by the growth. What’s worse, the combination of the two exists in its strongest forms if the parasite is in control of the colony (i.e. if the queen bee is the parasite).

It is my belief that the worst case scenario, The Dark Queen Scenario, applies to these human supercolonies.
