I answered in another comment , but here ' s the thingMayuri ' s death is unavoidable in every Alpha worldline , and the SERN dystopia is unavoidable in every Alpha worldline . Since Mayuri ' s death is directly linked to the formation of the resistance , the two events are linked as part of the same Alpha attractor . Same deal with Okabe witnessing Kurisu on the floor in a pool of blood . This is necessary for every Beta worldline , and every Beta worldline results in WWIII with the notable exception of the Steins Gate timeline , a modified form of the original Beta timeline . Since Kurisu giving the paper to her father is directly tied to the beginning of WWIII , and since Okabe not witnessing her would create a multiworldline feedback loop paradox , it ' s part of the Beta attractor field . I think I ' ve figured out the answer in my head , now the thing is explaining it properly .
