Which of these characters from "The Breakfast Club" would make the most interesting subject for a paper?

I need to write a paper for my abnormal psychology class. We need to choose a movie and analyze/diagnose a character with some sort of disorder, as well as tell how they can be treated.

Should I use: the Basketcase (Schizotypal Personality Disorder) OR the Criminal (Antisocial Personality Disorder)?

Other characters could work, but those two have the most symptoms that can be seen more obviously.
