Can you look at someone and tell if they are a sociopath or a psychopath? There's something about HKS that gives me a case of the "heebie jeebies". To me, his eyes are cold and dead-looking. I've looked at several of his pictures and the expression in his eyes never changes. I studied the one of him and Daniel sitting and talking with their caps on, and HKS' eyes are expressionless...he is smiling, but his eyes aren't.
Maybe I'm becoming paranoid from reading so much about this saga!
There is such a phenomenon described as the "psychopathic stare"- cold, fixed, almost reptilian. Trust your instincts and gut. And I see the same thing you do.
You are exactly right about Howie’s eyes. They are dead. Cold. Even when he is smiling - which is not that often.
