Many forensic psychologists, psychiatrists and criminologists use the terms sociopathy and psychopathy interchangeably. But there are clear and significant distinctions between them. There are similar traits but sociopaths and psychopaths also have their own unique behavioral characteristics.
A sociopath always tends to be nervous and is easily agitated. They are prone to emotional outbursts, may it be anger or sadness. Sociopaths usually prefer being reclusive but form bonds with others at times. The crimes committed by a Sociopath are rather spontaneous.
A psychopath on the other hand has no emotional attachments whatsoever. Instead of feeling them, they mimic emotions. They have charming personalities and are very manipulative. Crimes committed by Psychopaths are always planned. They are cool, calm and meticulous all throughout.
This article by Scott A. Bonn helps us understand the clear distinction between criminal psychopaths and sociopaths.
