Earlier quoted context omitted.
What's illogical about it? In fact being a psychopath is the most logical thing (promoting your interests with cold logic with care or mercy for others). All other behaviors need either a faith in some God or man-given morality, ethics, or emotions like love, mercy etc (which, as emotions, are not logical). Of course one can logically come to the conclusion that behaving moraly instead of like a psychopath is better…
Not really, Nash equilibria aren't necessarily the best outcome for any individual (cf the prisoner's dilemma). Cooperation is usually better than every-man-for-himself for everyone involved, hence why social animals evolve altruistic traits. Of course, selfishness works at the expense of an altruistic majority, but that's why people don't like to associate with psychopaths
In most actual real life situations you can get far ahead by behaving as a sociopath.

The thing is that as a sociopath you don't even have to show that you are that to people. You can still pretend to be altruistic (to your advantage) and still push your personal agenda whenever possible covertly.
