Mmmrgh.
I almost want to hugs this, but... dammit, I liked F/SN partly because it got away from that kind of thinking. I'm totally on Julian's side here, assuming they've at least tried to figure out the whatever without killing her (I'm just assuming from context that the plan is something like "kill Miyu, extract wish.")
Like, it sucks and part of the thing I like about Shirou is that he'll never give up trying to find a way to save everyone... but this scene reads to me like he just gave up on the world for Miyu's sake.
But a core theme in Fate, especially post Fate/Zero, has been the debate and struggle between the means and the results of saving the world. Is it worth saving the world if the path to getting there is forged from evil? Is it really salvation if it's forged from damnation? How does travelling down such a path affect a person, and is it worth the cost and suffering it causes?
And even then, back in F/SN there's always been the not-so-undercurrent that such a worldview is insane and outside the scope of a normal person, to the point that you can't be a normal person if you're going whole hog into it. Shirou's fucked up, Kerry's a broken shell of a man who's never fully grown up at heart, Amakusa's so into saving humanity as a whole that he's willing to just throw as many people into the grinder to get it down, and does anything really need to be said about Twice?
Of these four, two are the antagonists while the other two have to struggle as their viewpoints and methods are put through the meat grinder that is reality. There's another example in Mahoyo where Touko's appalled by Aoko's casual timeline dickery that's accelerating entropy massively all to save her boy-toy while Aoko goes 'Lol I'll deal with it later, bitch', but since Mahoyo's not fully translated I'll leave it out. Oh, and there's Siegfried who's life was unfulfilled because he did everything for the sake of others and not go for his own personal dreams and wants.
Nasu's always been big on highlighting the transience and the personal scope of man as the better aspects of man as a whole. Pretty much all his works carry this to varying levels; hell, even his D&D character (or whatever system Red Dragon runs on) is basically the consistent themes and aspects of his writing distilled into a single character. This shouldn't be all that shocking; hell, I was wondering when it'd pop up at this point, same as I am with Strange Fake.
