Most predators attack their attackers...but this beast...it destroyed everything. That was its function, after all...to ensure that no Kryptonian would ever be safe again.
But I've often pondered the role of Green Lanterns in Kryptonian history. There's a paradox. Without that tragedy and the chain of events it set in motion, we never would have ventured to Earth and lived beneath its yellow sun. We never would have reached our fullest Kryptonian potential. Now we can bring our race to new heights. I suppose, in that way, we owe the Green Lanterns a debt.
You have taken me for your slave and now ordered my murder, Waller. Zod reciprocates.
