That does suck, if its just being strong-armed. And, again, you do need some degree of contingency for when the players buck the system. So subverting the will of the villains by doing as-stated-but-not-as-intended executions of jobs could be fun. Dethroning the good king by getting him to implement a parliamentary democracy, rather than by stabbing him in the back. Burning down the orphanage after you've evacuated all the kids, and then moving them into a new luxury town home that you've purchased with your adventuring money. Whatever.

But simply having the GM announce "Your Paladin eats the baby because he has no choice" isn't particularly fun.
