I'm guessing that if you have a real sociopath none of those indicators are likely to be present because of the lack-of-remorse trait: those bodily signs indicate dissonance between one's awareness of the truth and what's coming out of one's mouth.
Is Yingling a sociopath? I don't know, but to have been doing what she does for decades -- as a non-Scientologist -- speaks volumes. She can't pretend to be unaware of what's going on.
Attorneys are pretty solid in their rationalizations.
While she's cashing her big fat checks, I'm sure she's telling the gawking onlookers that EVERYONE deserves representation.
As far as the criminal activities, she doesn't want to know.
It kinda surprised me when one of my attorney friends (criminal defense) told me he NEVER asks, nor does he want to know if his client is guilty.
Call me naive, but I was shocked.
I think that's partly for plausible deniability, but also to make it easier to lie to themselves.
The truth is like Schrödinger's cat to them.
