Do people die if they are killed? In Fate/Stay Night there's the famous scene in which Shirou speaks to Saber. The scene gained immense popularity across the web, and is usually accompanied by responses like O RLY? and You Don't Say!

The question is, does he actually say that? Is that line also written in the Visual Novel? Is this a translation error? Or is he just that stupid?
My understanding of the phrase is that he means:

People who are killed should remain dead


This is in reference to servants - he doesn't like that servants are resurrected souls. They should remain dead.
