>>70184082I think you're missing the point of Shirou's character. His way of life is fucked up because his existence is distorted as Kotomine's. The only time he 'heals' in life is in HF (that we see). He uses those 'ideals' as clutch to be 'happy', but he'll be forever an outcast.
In Last Episode, he lives an unhappy existence of a machine until he dies and is reunited with Saber.
In UBW, his future is left in Rin's hands.
Sakura is a murderer? Not really. Humanity is the reason why All Evils of the World existed (again in Hollow Ataraxia), she and Angra Mainyu were scapegoats used by humanity that brought the evil to themselves. Ironically, they were pretty innocent. That's the core of the Kotomine vs Shirou battle. Neither CHOSE to kill. Sakura was darkened and control by an entity who was also controlled.
If you really want 'real' justice? Gilgamesh got it right: kill humanity because it's corrupted.
