I know you don't like this Mike but I personally view MoS as a good move. Sure it causes misery but it places selflessness over selfishness. As seen by all the other bad ends after that one the chances of actually suceeding in saving Sakura were pretty slim and weighing the lives of her shadow nomming on the scale less people were effected negatively.
Sorry, that is just crap. Sakura is not a fucking statistic, she is a human being, and Shirou has
absolutely no right to judge her as worthy of death because of something she
might do. Further, he knows bugger all about what the shadow was doing or was capable of doing at the time, so that is no defence. All he has is some vague comment from Kotomine saying she will kill people, which he resolves to prevent.
You would put a dog down if it had rabies despite the really slim chance of keeping it alive and not biting down on people until they are free.
Sure, but you don't put a
human down if they have rabies, or any other infectious disease for that matter. Sakura is not a fucking dog, and I think that comparison is very revealing of your attitude to her, and to humans in general.
