For those who question the article by saying that perverse personality is different from Anti-Social behavior, they are very wrong.
The article is good, perversity in psychology refers to a deviation from the object, whether sexual or cognitive.
A sexual pervert, whether a voyeurist, masochist, etc. and a cognitive pervert such as an Antisocial. both fall into the definition.
Get informed, read and learn before commenting nonsense.
