Every time I see an evil comic book-style villain with a scared face I am reminded that that look is based in realty. Pre-war, many well-to-do Germans took part in a style of fencing that resulted in regular injuries to the face. A scared face was a badge of status. There were several prominent WWII leaders with facial scars not from battle but from fraternal fencing organizations. A few years later and the comic book supervillains had scared faces too.
