Sure. Bad choices shrink the pool from which future choices are made. I am defining a good choice as one that enhances your life somehow. A bad choice can directly limit future choices in many possible ways. I can die, be paralyzed, go to jail (limiting my experience), and so on, but just as importantly, a bad choice adds to the information that those who made the choice possess. So the new information can be used to evaluate future choices, you can either learn from the mistake and make a different choice, or you can make another bad choice. So the multiverse by its very nature encourages good choice. It is a sort of free will from the perspective of someone who has access to all the universes, even if isn't directly so for each instance.
That's a very limited usage of the word "bad", and not what I've been talking about. I'm talking about good and bad in moral terms, where bad choices very rarely directly lead to life-altering consequences.
