I swear everyone on this website is low IQ and incapable of understanding the nuance in why Joel was correct.
Here's a scenario where Joel would have been wrong:
Fireflies greet Joel and Ellie peacefully
Welcome them in to their base
Explain to both of them that they're trying to make a cure
Explain that in order to make the cure, they will have to cut open Ellie's skull which will indirectly kill her
Explain it would be for the greater good and promise and reassure that they wouldn't hoard the cure but try their best to share it with all mankind.
Give Ellie the choice to sacrifice herself for humanity or to preserve her own life
If Ellie chooses to sacrifice herself give her and Joel some time to say goodbye, and even welcome Joel to become a member and help protect Ellie's sacrifice by aiding their mission to spread the cure
They would almost certainly convince Ellie to take the plunge and Joel would accept it.
Instead here's what happens:
Joel and Ellie arrive at the Fireflies base
They immediately engage in hostilities and knock him unconscious
He wakes up and they treat him coldly, and refuse to let him see Ellie
Ellie has already been sedated and wasn't even told she was going to be sacrificed
Joel isn't allowed to see her or say goodbye, and is threatened when he asks to do so
Fireflies discuss killing Joel before he even makes a move to save Ellie
Joel decides this people are insane and goes to rescue Ellie
It's obvious to anyone who isn't a complete retard that the Fireflies aggression made it clear that Joel was in the right to save Ellie.
Also the kike CEOs words about the cure working *ARE* a retcon because he already retconned the lab in remake or sequel (i forget) where instead of the doctor looking like a psychopath in some shitty unsterilized lab he remade the doctor and lab look clean and professional.
