3+ years into the trump presidency, a question occurred to me that i never thought about before:

4. Currently, the DSM 5 groups the two together.

It’s one of four Cluster B personality disorders.

1) NPD (Narcissistic Personality Disorder)
2) Psycopath/Sociopath
3) HPD (Histrionic Personality Disorder)
4) BPD (Borderline Personality Disorder)

So, to answer your question, the DSM 5 already considers sociopathy and psychopathy to be the same (perhaps only differentiated by degree).

Personally, I think that all four Cluster B disorders are “the same” in the ways that really matter. I don’t see any value in distinguishing between them. That said, mine is the minority opinion.
