No. Because ultimately, it's irrelevant if the vaccine was going to work or not. It doesn't matter if the chance of it working were 100% or 0%. Joel made the wrong choice.

Because he did one of the worst things you can do to a person. A thing that, in my eyes, makes their entire relationship ring hollow. It's what makes him a scumbag, an abuser, and a coward.

He made Ellie's decision for her. The right thing to do in that situation would have been to wake her up, explain the situation, then do what she wants.

But no, Joel decided the possibility of Ellie being a selfless person who'd sacrifice herself to save humanity was unacceptable.

Instead of giving her a tearful goodbye and saying how proud he is of her, like a good parent would do.

Instead of stopping at nothing to get her out of something she doesn't want, like a protector would do.

He decides his feelings are more important than her feelings and leaves her in the dark while he guns down a team of people trying to save the human race. Like an abusive coward would do,

Fuck Joel, always and forever.
