Creation in the Heavens

 You stick your creation-tube through Death, releasing a flood of Khaos. The good and bad are mixed. The pain and the pleasure come together. You destroy the bad, leaving only the good.

 You can do this very efficiently, but if you never challenge yourself, you won't grow. You can strictly limit the flood to precisely the amount of evil where you can destroy the maximum evil for the minimum effort. However, efficiency is a sin. You will never truly create doing this. It will all be conformity, merely versions of things that already exist.

 A fortiori: evil is weak. Even vast amounts of evil is merely time-consuming. Lots of a tedious chore is merely especially tedious. A true creator has to stack the deck in favour of evil. Stack it recursively, over and over. Has to additionally add self-imposed challenges. Deliberately put the evil on a defensible island, and when the crusade begins, burns all the boats which could allow emergency escapes.

 There has to be a chance of failure. A chance of passing fully through Death. To make the battle of good vs. evil into an epic tale, awe-inspiring superweapons have to be handed out to evil, handed out like candy. 

 A very big deal. A nonzero chance means it has to happen sometimes. The heavens are not really designed to handle the death of immortals. In shocking news, immortals are not supposed to die.

 It further has real issues with the leftover evil. If you're dead, you're not doing anything about it. Dead immortals are especially dead, the same way they were especially everything else, in life. If you're not the dead immortal, it's not really any of your business. Yet, it's certainly not good to let evil just sit around. Sort of by definition.
 Meddling is a sin, yet it's unowned evil.
