You know how in Tron: Legacy, Flynn represents God and CLU represents Satan? And the grid is destroyed when Flynn and CLU "re-integrate".
Do you think that's how this reality ends as well? God "reabsorbing" Satan? I feel like the creation and destruction of reality occurs in an endless cycle, and God created Satan to serve some important role.
Ultimately, it's all about our souls, I think? The destination of our souls, or maybe the transformation of our souls into something greater? idk.
