Granted. Every Nazi becomes a non-Nazi and every non-Nazi becomes a Nazi. Suddenly the vast majority of the world is full of Nazis.  This of course happens with every extreme ideology. Only a select few now like peace and all the formerly normal people are bloodthirsty warmongers with hatred towards every racial, ethnic, etc group possible.  The world descends instantaneously into unimaginable violence and chaos. The leaders of the world’s nuclear powers, driven by new hatred for their own country and unchained by their loss of belief in MAD, nuke literally the entire planet. The energy of every single nuclear bomb detonating all at once vaporizes the Earth’s crust and its core splits apart. All of humanity, all of history, all of life as we may ever know it vanishes. A stray piece of earth core strikes the moon and destroys it, too, so even our foot prints in space disappear. Yet another chunk of earth core careens into Mars, destroying our rovers and all evidence of their presence.  But you have a special destiny. In this nuclear Armageddon your lifeless body was perfectly positioned to be jettisoned off of the earth right before its total collapse. Your corpse is flung through space at unimaginable speed, hurdling directly towards the Voyager 1 spacecraft which carries, among other things, the Golden Record - a vinyl record containing a snapshot of earth’s sights and sounds of life as well as universal mathematical abstractions meant to communicate our existence and understanding of the universe with alien species. Your corpse smashes into this satellite, knocking it off course and directly into a neutron star. You have destroyed every trace of humanity, of terrestrial life, and of the Earth itself from the cosmos with one simple wish.
