Cain and Abel

   So I’m wondering if the show will ever address Cain and Abel. Technically, would Cain be the first sinner ever for hell besides Lillith, and Abel be the first winner ever? Would Cain have had enough experience to survive in hell all this time, to become a big figure, or was he just lost as more sinners showed up?  Therefore, technically, since Abel would be the first winner, would he have the same recognition as his father, Adam? These questions have been on my mind for a while. However, I find it unlikely that they will show up at all. What are your thoughts?
