Could I be a sociopath if I don't like anyone?

Sociopath. A sociopath is a person with antisocial personality disorder. This involves behavior that is usually criminal or against societal norms. It does not mean not liking other people.
Antisocial. The modern clinical term for sociopathy is antisocial personality disorder. The hallmark of this disorder is the person seems to have no conscience, or sense of morality, or right or wrong. This person cannot empathize with others, is opportunistic, predatory, and often thrill seeking. An example of this would be Charles Manson. Any licensed mental health professional can make this diagnosis.
