David Cage has said that he doesn't want death to be the end in the game. BUT you are put in multiple situations where you will die if you do not push the right buttons. Normally, he says, you would finish the story with the other characters.
However, what if you kill off all 4 characters in the game? Unless there is one character that cannot die, then death is equally as much a concern as it always is. On the other hand, I don't know if I would care for a game that you could fail every challenge and still win. What will they think of next? Games that play themselves?
On the other hand, maybe there is a secret character - the killer - and if you kill your other characters off, you play as the killer till you are caught.
