Jane, the picture you describe reminds me of the Bible's description of the man of FIERCE COUNTENANCE, which certainly fits him to a T. I have seen some photos of him where (in my opinion) he LOOKS LIKE he is literally glowering with murderous rage!  It's like coming out his eyes! Course, as I said, it is just my opinion, but the EYES reveal a lot about the soul and some people simply CANNOT HIDE what is in their eyes! They are the "window" to the soul.
