You appear to be describing antisocial personal disorder and/or a lack of emotional self regulation, not necessarily psychopathy. The fundamental difference between sociopathy and psychopathy is conscious vs. unconscious behavioral patterns to deceive, manipulate, gain power, and control others. The psychopath doesn't know why they do it, the sociopath intends antisocial behaviors to achieve goals.

Oh, on further reading I was wrong. The dictionary was off, but psychological journals are a better source.
