First of all, ASPD is the same thing as psychopathy, and it's not something that's "developed" (let alone through another disorder). It's something you're born with. It's genetic and hereditary. http://www.sociopathworld.com/p/portrait-of-sociopath.html But psychos sure wouldn't mind having yet another "cover" like "NPD", "BPD", "HPD" etc, which are all just flavours of psychopathy at best, if anything more than labels for whatever set of mind-fucking tactics a particular psychopath has decided to employ.In one study, over 80% of the variation in the callous-unemotional trait across the population was due to genetic differences. In contrast, the effect of a shared family environment was almost nil. Psychopathy seems to be a lifelong trait, or combination of traits, which are heavily influenced by genes and hardly at all by social upbringing.
