I see the terms, sociopath and psychopath thrown around loosely a lot specially on youtube even by so-called "experts". I think part of the reason for that is personality disorders of the cluster 3 type, BPD, NPD, and ASPD are often considered dangerous or violent and therefore the tags are placed on them. I suppose it all depends on what your definition if sociopath and psychopath is. While it's certainly possible for NPD and BPD to be such, it's not nearly seen in BPD.
