Q. What Do I do after that???
 
 
 
A. Okay so I kill Belial now what?
 
          Well, you can now load the game before the battle and let him kill you this time. You will see a different ending. And then you can start a new game and choose a different attitude for Luther. If you favor Dawn this time, try to oppose her now. The ending will be different and.. well you go see.
