The outcome is, and possibly the motivation, but you don't have to fudge the dice here. It's unnecessary.If I look down behind my screen, and see that the six hits, and realize that my monster is incorrectly statted, functionally, fixing the stat and fudging the dice in this scenario are identical.
But I personally take it a step further and don't change my prep either. The players have no expectations that any given fight, for example, will be "balanced" or "level appropriate." It's on them to decide what to do in the face of that reality, not for me to change something midstream because I don't think they can handle it. I have faith that they'll figure it out, and my faith is usually well-placed. And if it goes wrong, that's okay - we already agreed that the cost of failure is fun for the players, if not so much fun for the characters.
