There is research on this topic, although it's riddled with flaws, some of which become almost unavoidable in a practical sense. For example, those who have ASPD often had conduct disorder. One of the criteria for conduct disorder is harm to others more so than non-conduct disorder children. Ideally, researchers would have to choose ASPDs who did not satisfy any violent-related criteria, although that's difficult. Researchers often take prison or jail samples because there tends to be a high density of ASPD people, which can lead to a self-fulfilling prophecy as the person may have committed a violent crime or the living conditions have made them more aggressive. In theory though, ASPDs would show greater anger, although that need to equal physical harm.

Most psychopaths have ASPD but not many with ASPD are psychopaths. Sociopathy is a general term that's not clearly defined and is neither a medical nor legal term (psychopathy is a legal term).
