Hal was a hero that tried to stop the death of millions in his home city that was turned into an anti-hero that tried to save the original universe that became a villain that destroyed the Corps that redeemed himself by sacrificing himself for the solar system that returned from whaterver purgatory he was in to become the Wrath of God that was returned into corporeal form to defeat Parallax that became a hero of the Corps. I don't think Hal needs to go down that road again.
