90's kid

a) the procedure that would 100% kill Ellie had an incredibly low success rate (the doctor mentioned in his recording that every previous operation with other test subjects had failed) b) the same recording mentions cerebrospinal fluid having been extracted, meaning they were capable of performing a non-lethal spinal tab, but they’re unable to perform a non-lethal biopsy or craniotomy on Ellie? (this may seem like nit-picking, but actually further solidifies my point about how incompetent the Fireflies/Abby’s dad were/was) c) to add to their immense incompetence, mere hours after receiving Ellie they decide to IMMEDIATELY KILL THE ONLY PERSON KNOWN TO BE IMMUNE as oppose to keeping her alive for as long as possible to run every single test in existence on her. But let's paint a picture of the best case scenario, which is Jerry, the absolute legend that he is, actually manages to get a vaccine out of Ellie, what happens then? a) How are the Fireflies, who are nearly extinct at this point, supposed to MASS PRODUCE and NATIONWIDE DISTRIBUTE a vaccine? That is logistically impossible. b) More than likely, they would use the vaccine as a bargaining chip against FEDRA (granted, this is more a guess than a fact, but to believe they wouldn’t take advantage of the vaccine in the fight for political power against the government they’ve been fighting for years is beyond naïve). But let’s be even more generous: turns out the Fireflies are the most altruistic resistance group to have ever existed, they actually manage to produce and distribute the vaccine into every last corner of the country, everyone is immune. What now? a) You might be immune to spores and bites, but your immunity doesn’t help you when a clicker rips your throat out or a bloater crushes you to death, the infected can still kill you in numerous other ways. b) The faction wars going on are not gonna disappear overnight. WLF and Seraphites will continue to kill each other by the dozens every day, one could even argue that introducing a vaccine into the conflict would only cause things to escalate further. c) Numerous cannibals, hunters and bandits still roam the country, they will not abandon their practices overnight and they are arguably a much bigger threat than the infected to begin with. Just because everyone is immune does not mean that the world returns to sunshine, rainbows, and flowers. To imply that it would, means being simplistic and naive beyond reason. It should be obvious by now that Ellie’s death WOULD NOT HAVE IMPROVED ANYTHING. The chances of actually getting a vaccine are slim to none, the chances of vaccinating everyone are even more dour, and even then the overall situation would not improve much. With such bad prospects I wouldn't be willing to sacrifice my child either. (I am aware that an argument can be made that none of these factors had an impact on Joel’s decision to save Ellie, yet they’re still crucial when making a judgement about the Fireflies/Abby’s dad). To summarize: a) Abby’s dad was incompetent and a horrible person (his conversation with Abby in the second game tells us that he would not be willing to sacrifice his own child, but if it’s someone else’s it’s a-okay for him). b) The Fireflies were a malicious and incompetent terrorist group with messed up morals. c) No, Joel did not doom humanity. Subsequently, Abby’s quest for revenge was not justified because the Fireflies and her dad were never justified in their actions to begin with. And this is only solidified by the second game having to retcon the hell out of all these arguments I just painstakingly illustrated and explained in order to even attempt to have Abby’s motivation be seen as justified. Only one example being how it was clearly established in the first game that they had MULTIPLE doctors in Salt Lake City (Marlene: “The doctors tell me that the cordyceps, the growth inside her, has somehow mutated.”; Ellie: “She said that they have their own little quarantine zone. With doctors there still trying to find a cure.”). Yet in the second game we are told by
