Sociopaths are generally created by circumstances. The folks you mention choose to do what they do. Socially sanctioned sociopathy, if you like.

Sorry if this is the fallacy of "appealing to authority," but my husband is a psychotherapist. Of course they "choose" to do what they do, that is what a sociopath (now known as "antisocial personality")
is - someone who chooses to live at the expense (whether financial, emotional, health-related) of the rest of society without regard for the damage it causes.
I doubt that SB and JvP are sociopaths. When they are confronted they virtually always respond with some amount of anger. A true sociopath wouldn't respond that way. I consider them immoral rather than amoral.
Sociopaths
are indignant if called on their behavior. They will explain, justify, swear that they were forced to do what they did by society, the therapist, their spouses, pick something. They are amoral because they have no way to conceptualize or internalize the concept of morality.
A true sociopath capable of atrocities would be huddled in a dank basement wiring a pipe bomb by the light of a 50 watt bare lightbulb, or leading his flock of believers to Guyana for a Kool Ade and strychnine cocktail, not on national television selling books and magic prayer cloths.
He's only going to be wiring pipe bombs if there's some kind of payoff
for him in the job (think mob hitman.) Selling books and magic prayer cloths, on the other hand, have a great payoff, and, if done carefully, have almost no downside for the scammer. (Jim Jones was probably a narcissist, not antisocial personality.)
Diagnosis is tricky because symptoms and indicators can overlap, but an antisocial personality is not going to be a suicide bomber. No payoff. Check DSM (Diagnostic and Statistical Manual, the resource used for official psychological diagnoses) IVR for the latest information.
In my opinion, most professional psychics, faith healers, etc., are antisocial personalities. There may be a few who are genuinely self-deluded and believe in their own "powers," but by far the vast majority are dangerous rip-off artists.
