re: The real truth behind the ASPCA dog in shelter ads.

There's nothing "possible" about that type of symptom being evidence of serious psychopathy.

It's one of the major indicators - which can show itself as early as the childhood years - and no, they don't grow out of it.

The post said "hints" of psychopathy - is that enough of a qualifier?

The successful writer Ian Fleming had that dysfunction all the way from childhood.

Writing was part of his regimen to sublimate and channel his sadistic tendencies elsewhere.
