Maybe it's saying that there's purity in being completely rotten?

Also...rot/festing CAN purify things in some extreme circumstances. Look at how they used to (and maybe still do) use maggots in the real world. Let a wound fester, then use them to purify the toxins and bring it back to normal.

I doubt that's what the author is getting at, but...there IS some sense of purity in rot, in that it brings things back to a "pure" state in the end.
