Having no conscience is HUGE! You can't turn conscience off and on. You either have it or are possibly a sociopathHe just didn't give a ***** about anything is my take on the comment.
The VICTIM in another trial I followed closely for years (and still am) called himself a "sociopath" in an email to friends.
The defense used that term against the dead victim mercilessly during trial. The victim was not a sociopath, he was a compassionate, loving, empathetic man who used that term to express , clumsily , that he hadn't always been considerate enough of the women he dated.
Sorry, but there is no way I'm going to take those words literally and at face value, much less to conclude from them Harris lacks a conscience or is guilty.
