Okay, you're taking this way too personally. Sit down, have a sip of tea, light a nice candle/incense, and remember we're talking about writing fiction, not you or people you know.
I didn't say "supposed", I said that those things happen. Yes, not everyone is a monolith and you can find ASPDs who become surgeons so they can cut people's hearts out and get praised for it because they put a pacemaker in its place. Yes, there are "narcissists" (in the colloquial sense) who just vogue in a mirror (that's not NPD, though, unless it is somehow harmful). And so on. (And note, in case this is what you're getting hung up about, autistic people do not have CBPD. That's a common misdiagnosis by amateurs and self-diagnosing people that is more harmful to autistic people than useful.)
But those are exceptions. The people you know are not a statistical sample. The people you know in any situation, any context, any discussion of any topic are never a statistical sample. Not unless you have literally thousand of friends, which hardly anyone does.
"Some criminals" is not what I was talking about. Serial killers (not including mass shooters, which are different) very frequently show the symptoms of ASPD (often being diagnosed after being caught), and often with comorbid NPD and/or HPD. There are some exceptions (the "Son of Sam" had schizophrenia, which is an uncommon case), but it's more common than not. So when fiction writers decide that their serial killer character has ASPD or some other CBPD, they are at least getting something accurate about how such a character often is IRL. And remember, I'm not saying all people with CBPD are serial killers; I'm saying serial killers usually have CBPD. That should make logical sense.
