(TV) Dangerous Exploits follows a young man’s journey from a womanizer to a brilliant sociopathic manipulator, starting with his graduate studies of psychology at Arizona State University.

Ok, your protagonist is obvious, the young man, but what is his goal(s) that he is trying to accomplish? Is it to become a "brilliant sociopathic manipulator"?
And what/who is the antagonist that he must overcome? What is the conflict in your story?

hmm very good point, that is definitely something I need to think hard about for this logline; why the viewer would be on his side

>>but you're on his side.

Are we? Why should we be? Give us a good reason. Which, I admit is difficult to do given the constraints of a logline. What is there about your sociopath that will engage our interest, perchance sympathy, even as we don't like how he operates?
