honestly they just need to do a simple change since it's not like" Sunernatural" invented this design of Mark of Cain out of nowhere. It's just Phoenician or Paleo-Hebrew letter "he" from Tetragrammaton (on the image the first line is in Phoenician, the second one in Paleo-Hebrew, the third one in square Hebrew ). Some rabbis believed that the mark of Cain was one of the letters of the Tetragrammaton.
