One can make it sound like a joke, just like idiots try to make PTSD sound like one. But it's real. Histrionic personalities can drive you crazy as they shift from "charming" and "seductive" to demanding and hysterical.
The phrase "drama queen" should sound familiar.
OTOH, whether JS is histrionic or not would seem to have absolutely nothing to do with what he's charged with. And the APA doesn't considers it a "disorder," not a form of insanity, so it wouldn't keep him from prison anyway.
