Perhaps chaos (or free will) is a matter of perspective and context. Perhaps we can only experience the free will as it pertains to us at our own respective level; whereas, when you step at another higher level, this flux (cause and effect) that we call life forms first, a discernable pattern, and then no movement ... no time? ... at all. Perhaps what you call "karma" has no discernable effect at all or becomes a plot outside the graph in those higher levels. "The Devil is in the details" ... so to speak.
The Big Bang becomes the Big Crunch and then renews itself into another Big Bang a' la "the Restaurant At The End Of The Universe"? You do the hokey pokey and you turn yourself about and that's ... really ... what it's all about.
I'm such a victim of pop culture. :/
