I like this idea as well, and to be honest, I don't rememer a single RPG (at least dfor the PC) where this concept has been fully worked out.
This comes near to my concept of "fighting for something" vs. "fighting against something" (there once was an old "Alrik's different angle" article over there at RPGDot).
