Was this movie intended to make the audience question whether or not they treat females...

... guilty of committing, as this movie portrays, a disturbing crime (and do watch it and see that undeniably haunting and disturbing scene towards the end), differently than their male criminal counterparts, and why? Or did it just intend in its own weird way, perhaps, to tell a horror story?

And it also just HAPPENED that the female, "the fan" of the movie title, happened to be a gorgeous and vulnerable 17 year old young lady.

P.S. Understandably, but with controversy, this movie caused outrage and yes, to repeat that word, controversy around nudity surrounding our title character in question. BUT... Did anyone also feel that this movie was also being outrageous and controversial by portraying her character as... an obsessive criminal psychopath? Or was the latter part rather normal with audiences on most if not all levels?

P.P.S. Its still a very good film though, 8 out of 10 I give it. And fans of films involving femme fatales, cannibalism, females turning to dark sides, Germany, early 80s, music etc, as well as works like "Play Misty For Me" (1971), "Fatal Attraction" (1987), cannibal themed horror including the recent one "Raw" (2016) (also involving a girl in question), "Repulsion" (1965), the works of Jorg Buttgereit including his "Nekromantik" movies, some other little seen American fare like "Nobody Loves Alice" (2008) and also films like "May" (2002) etc, give this one, the classic slice of early 80s cult outrageous, surreal and disturbing, maybe even feminist (?), slice of Kraut horror "Der Fan" ("The Fan") (1982) a look, I own the uncut version on Blu-Ray.
