They say only Good can create, whereas Evil is sterile. Think Tolkien, where Morgoth can't make things himself, so perverts Elves to Orcs for his armies. But I think this gets it entirely backwards; it's Good that just mutates and twists, and it's Evil that teems with fecundity.

Imagine two principles, here in poetic personification. The first is the Goddess of Cancer, the second the Goddess of Everything Else. If visual representations would help, you can think of the first with the claws of a crab, and the second a dress made of feathers of peacocks.

The Goddess of Cancer reached out a clawed hand over mudflats and tidepools. She said pretty much what she always says, "KILL CONSUME MULTIPLY CONQUER." Then everything burst into life, became miniature monsters engaged in a battle of all against all in their zeal to assuage their insatiable longings. And the swamps became orgies of hunger and fear and grew loud with the screams of a trillion amoebas.
