Is there a solution?
The obvious solution would be a world in which, at the very least, the psychopath - in government or in society - would be forced to be responsible for unethical behavior. But game-theory modeling demonstrates that selfishness is always the most profitable strategy possible for replicating units.
Could it ever be an evolutionarily stable strategy for people to be innately unselfish?
On the whole, a capacity to cheat, to compete and to lie has proven to be a stupendously successful adaptation. Thus the idea that selection pressure could ever cause saintliness to spread in a society looks implausible in practice. It doesn't seem feasible to outcompete genes which promote competitiveness. "Nice guys" get eaten or outbred. Happy people who are unaware get eaten or outbred. Happiness and niceness today is vanishingly rare, and the misery and suffering of those who are able to truly feel, who are empathic toward other human beings, who have a conscience, is all too common. And the psychopathic manipulations are designed to make psychopaths of us all.
Nevertheless, a predisposition to, conscience, ethics, can prevail if and when it is also able to implement the deepest level of altruism: making the object of its empathy the higher ideal of enhancing free will in the abstract sense, for the sake of others, including our descendants.
In short, our "self-interest" ought to be vested in collectively ensuring that all others are happy and well-disposed too; and in ensuring that children we bring into the world have the option of being constitutionally happy and benevolent toward one another.
This means that if psychopathy threatens the well-being of the group future, then it can be only be dealt with by refusing to allow the self to be dominated by it on an individual, personal basis. Preserving free will for the self in the practical sense, ultimately preserves free will for others. Protection of our own rights AS the rights of others, underwrites the free will position and potential for happiness of all. If mutant psychopaths pose a potential danger then true empathy, true ethics, true conscience, dictates using prophylactic therapy against psychopaths.
And so it is that identifying the psychopath, ceasing our interaction with them, cutting them off from our society, making ourselves unavailable to them as "food" or objects to be conned and used, is the single most effective strategy that we can play.
It seems certain from the evidence that a positive transformation of human nature isn't going to come about through a great spiritual awakening, socio-economic reforms, or a spontaneous desire among the peoples of the world to be nice to each other. But it's quite possible that, in the long run, the psychopathic program of suffering will lose out because misery is not a stable strategy. In a state of increasing misery, victims will seek to escape it; and this seeking will ultimately lead them to inquire into the true state of their misery, and that may lead to a society of intelligent people who will have the collective capacity to do so.
