Interesting. I remember a Tales of the Green Lantern Corps where Tomar-Re (the piscine looking GL) was up for retirement from the Corps, when the Guardians held an inquiry into his failure to keep Krypton from exploding. It seems he was to delay Krypton's destruction until one Kryptonian, Kal-El, grew to manhood, when the Guardians prophecized that he would become one of the galaxy's greatest heros. BY this, they interpreted it that he would become a Green Lantern.
After all was said and done, the Guardians shrugged, and let Tomar-Re off the hook. Have a nice retirement.
