The Importance of Free Will

If there was only one universe and what you did is what you did, I think you can still have free will according to my conception. But it's far easier, of course, to know that there isn't only one universe that copies of you actually did do otherwise. What free will is about is about creating the knowledge. And you would still be creating the knowledge even in a single universe picture. Right, yeah I'm just extending it beyond human action. Maybe Sam is somehow grappling with this notion of the real existence of other physical realities,. namely other parts of the multiverse, this possible.
