Humans are longing for humanity's extinction.
This sounds illogical, but it's actually quite reasonable; just add some qualifiers.
Humans from a certain time string on parallel universe parallel Earth A long for the extinction of humans from other universes, other Earths, other time strings BCDEFG...
Hmm, doesn't it immediately become reasonably cliché? But this is the truth.
The humans of some string in All Heavens and Myriads of Worlds want to destroy all other humans from parallel universes, parallel worlds, parallel Earths, to exclusively rule All Heavens and Myriads of Worlds, consolidating world lines into one, ensuring they are the only humans.
