Ginny single handedly caused the God Valley incident by calling Rocks and Roger there and set everything into motion from the defeat of Rocks, rise of Roger and Whitebeard once Rocks was out of the picture, legend of Garp the hero of the marines, Kuma and Ivankov's escape to help form the revs with Dragon, Kaido getting his devil fruit so he could become an emperor and take over Wano, Kuma getting his which lead to Kuma saving the Strawhats repeatedly, Roger finding Shanks in the chest, Shanks being a pirate instead of a CD and influencing Luffy, etc.

She caused all of it by leaking God Valley's coordinates.
