Interesting. I used to think psychopaths had certain immunity against suicidal behavior, but turns out that idea of Cleckley’s is now considered outdated in literature, at least according to ”Psychopathy, Antisocial Personality and Suicide” by Verona, Patrick & Joiner. (In their own study, they too found positive correlation between the impulsive/antisocial component of PCL-R (F2) and suicidal behavior.)
