Do ppl actually have ted bundy/jeffrey dahmer paraphernalia ?

i mean i understand why people find them interesting but didnt bundy have groupies at the trial?why? even this girl in class one time said dahmer was her favorite serial killer.i mean lol.i get it they might find him attractive in a dark way.i think dahmer was just lost he seems like a normal human being in his interview with stone. ted ill say was entertaining well spoken didnt studder knew how to lie in an interview. its weird too because both were attractive males in their youth especially dahmer why would one even do that. didnt they study dahmers brain after he died? both had a normal childhood didnt they?or is it they were born like this?what was dahmers main disorder necrophilia?and ted's ?
