Let's test the title against proposed alternative with one sentence in the article:
"even though that flow is unproven in the scientific literature on psychopathy"
So, a lot of speculation with no evidence to back it makes the existence of psychopaths a myth. Further, the article intentionally ignores research that supports the existence of people with their alleged traits, even neurological differences. Pop psychology and religious rhetoric are far from the only things that went into it. So, the article's claims are unbalanced, weak, and defeat themselves for now with above quote.
