Explanation:

To understand this answer we have to analyze it. First of all the antisocial personality disorder is a personality disorder in which the subject manipulates, limit, and exploit someone else to obtain a benefit from it. So, it's one of the most dangerous disorders because they violate the rights and freedoms of other subjects. Second, the disorder has a lot of variables influencing its origin, one of them is genetically predisposed, which are influencing because it is deeply rooted in the subject. The rest are conceptualized as environmental factors and all can be controlled. But the amount of conditions that can make it develop has given the DSM a difficult time. That's why it is so studied.
