Redemption: the will's revenge against time
The will cannot will backwards, so it hates time and invents punishment and the afterworld.

Powerlessness turned into doctrine
This speech carries the book's harshest diagnosis, and its target is not a school but a situation: the will can go only forward and can do nothing whatever about what has already happened. What grows out of that Nietzsche calls the spirit of revenge. Its place in the argument is to gather a set of apparently unrelated doctrines — retribution, guilt and punishment, another world — under one provenance, so that a single line of questioning can handle them all.
Swapping a word's definition
In the same speech Nietzsche takes a religious word for his own use: redemption. Its place in the argument is to offer an exit that does not depend on another world: since 'it was' cannot be altered, what can be altered is only its relation to the present. This step also explains why chapter 6's instrument has to come after this chapter — willing backwards first, and only then any question of wanting it all again.
The shape of the spirit of revenge
What is being reconstructed is the thought behind the speech's assertions. The original gives only images; the structure below is added by this course, and the third premise is added entire.
Cracks in this reading
The 'redemption redefined' reading as a testable specification
The reading under test: this speech defines redemption as willing backwards over what has happened, not as being saved out of the world.
