What is the triad the three main symptoms of having conduct disorder or antisocial behavior?

Disregard for others: There is not really a triad for antisocial pd, but it is characterized by a disregard and violation of the rights of others. People who suffer from this disorder think they have the right to exploit, harm or use other people. Some scholars theorize that they suffer from superego lacunae meaning that their conscience never developed. They may display impulsivity, aggressiveness and lack of remorse.

Antisocial: 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. This person delights in outsmarting the system, objectifies people, and simple does not care about anyone but themselves. An example of this would be Charles Manson.
