Yeah, I've definitely met WAY too many people in my life who've tried to use "but I have a disease/I had a bad childhood/I never had a pony" as an excuse for their unacceptable and/or assholish behaviour. That a mean, rotten personality can exist independent of mental illness, I totally believe.
OTOH I think the doctor writing that article is copping out, a bit. He mentions the guy described above obviously has anger management problems-- as a therapist isn't it his job to teach people like that how to, er, manage their anger? It's very, very true that medication doesn't necessarily help a problem like this but IF the guy is willing to try (and that is admittedly a big IF) therapy actually COULD, conceivably, turn him into less of a rageaholic asswipe (not with medication but through therapy sessions). Allowing Mr. Rageholic to write it off, either by saying "I have a problem with anxiety" or "I'm just a mean-spirited asshole" seems like a cop-out for both therapist and patient.
Eh. I'm no expert. Christ knows getting someone like that to change their stripes is usually an exercise in frustration, anyway.
