I can't remember playing a game where I actually said to myself "I went through all of that, for that?" I mean, I get that the writers were tying to be all dramatic and poetic and stuff, but to arbitrarily deny the human race a possible cure was just asinine.
The way I understood things, the cure was all but certain. Marlene had a vision and a certain infrastructure in place, but chances were high Ellie would just plain die like the others, sacrificed to the idea of a better tomorrow, but no proper guarantee for success. Besides, given her political stance and the whole 'we are the new blood' vibe of the Fireflies, I am not too sure things would automagically turn out A-OK if the cure was really to actually happen.
Also, please bear in mind that Joel started out on this quest just wanting his guns, his merchandise back. In his view, they were stolen from him as they were rightfully his, whatever ideas and implications might be derived from that.
In the course of this journey, Joel lost everything and everyone. And, deep down, he felt that he could, maybe, fix the biggest failure, the biggest loss of his life. He lost Sarah, twenty god-forsaken years ago. Now he found himself stuck with another girl, a girl he did not want or care for much. And then... she's eventually the only thing in the world to him. The only thing he wants. The only thing he wants to be safe. The only person that matters to him, as all the others are dead anyway.
So... is it selfish? Sure. Is it pathological in nature? Yeah, I think so.
But it's damn human if you ask me. And our thoughts are free to wander as we contemplate what might come after we and the game part ways.
I cannot but think it's excellent, as I tear up just going through the story in my mind. Joel's life sucks, but I'm glad I was allowed on this one particular ride. It's just awesome.
