Not all Geth could have possible achieved sapience simultaneously, I don't think. It takes some time for a platform to be assembled in a large enough cluster of programs, and to remain fixed in that configuration to become sapient. Otherwise, they have merely the capability to become sapient through the aforementioned circumstances.
Also, we don't know if the Quarians began immediately with the destruction of the Geth. They could have begun with deactivating them to investigate the developments, and the Geth reacting violently in defense of these less aggressive actions for all we know.
We can't be sure if all Geth killed organics in self defense, or if some did so in that manner and others actively decided to attack organics as a counter-measure of anticipated violence in the same was that Quarians are accused of.
Also, you cannot assume that all Quarians were in favor of the war effort. Soldiers could have easily been following orders they absolutely did not wish to follow. And we know nothing of civilians.
There were Germans that tried to hide some Jews from ****s during the Holocaust. Not all Germans were in favor of the "Final Solution." While not completely a similar situation, look at a person like Zal'Korris as an example, and imaging someone with that same mindset alive during the Morning War. Quarians could have been trying to hide Geth that they held sympathy for from Quarian soldiers coming to eradicate the perceived threat on orders.
"The Quarians" are not a single entity, and may not at all by devoid of sympathy in the entire event, is my point. It's as big of a misconception to assume that the Geth are guilty of being a threat to all Organic life, to assume that the Quarians are guilty of unified and coordinated genocide of the Geth.
However, here is a concession I will make. I will agree that the Quarian decision from somewhere within it's government to erradicate the Geth is indeed the definite cause of the Morning War (and absolutely the wrong decision period.) I just don't agree with condemning all of the Quarians alive during the time of the Morning War as having been part of that plan.
