To your hypothetical sentient person with abstolutely no care for other sentient beings, the sociopath would be weak for fulfilling his emotional needs rather than to gain power. Hedonism is as much of a weakness as morality.
Not sure what your saying here, I made no hypothesis.
A sociopath is impossible to just pick out of a crowd, being they are more than capable at feigning compassion, empathy and morality. They can exploit these things in others, and will do so as long as they can without being caught. This is the inherent advantage they have over everyone else.
If the sociopath's strong desires include power over others, then they have the advantage of not being constricted by a conscience.
