No i dont mean physical attractiveness. I mean ugliness. Of course physical attractiveness is a big deal. But I mean ugliness, its another thing. When someone has an evil grin, evil eyes, evil clothing, moves with evil intent, every gesture of his body shows ugliness.
We humans read gestures and we derive intent from them. Basically the way you walk, the way you send signals that suggest hostility and cruelty, these things make you ugly. And ugly = evil. The way you dress show your personality. The wrinkles on your face show to the world what was the most common face expression you did for all your life, and after a certain age you personality is your facemask that will be worn for the rest of your life.
The way you focus your eyes, your posture, tone of voice, how fast you do your gestures, which ones. All things ugly communicate evil to the viewer. Which is why soldiers are trained to be presentable, speak properly, walk properly, have respect, so on.
So I was thinking, observing pics of heroes and saints, even 1 glimpse of their face tells their whole story. If someone is ugly, you think "that guy must be evil", and you often are right about it. Its very rare that someone ugly is also good, usually ugly =evil.
