Axel..

 To continue on the current test Subject the sociopath while can be incredibly intelligent as far as I.Q. is concerned , but develope emotional issues based ( i would just like to take this time to remind everyone I am doing a dissection of Jeremy "Axel" Rose  as a student of psychology .) on their previous socio-sexual interactions. Therefore if the current subject has sexual  problems , it's seed is in the person's past and would of been characterized as constant masturbation, incest, and homosexuality as a means to dominate the other men in the inner circle, as a means to establish a permanent place with in the  social situation.
            At this the sociopath is king as long as the society exists (their society, which was made uniquely to take out their devious a-sexual fantasies ) so at one point the sociopath  goes beyond sex to dictate and dominant. Secondly, then Jeremy must not know what love is , so they cannot deploy those chemicals linked to falling in love because most of the associations they have are not directed towards anything positive. So papa Iggy never showed little Jeremy love just acceptance at this point I  should denote that the sociopath believes that everyone must believe or think like them if not they will develope ways to make the group around them submissive .
