Comments of chapter undefined of Fate: I Will Eventually Become the Hero of Justice

The story is going quite well, but just one thing doesn't quite add up. The amount of Evil that Shirou had accumulated in his time here. Technically speaking, wartime is were most of the evil is generated, even if less than the amount in Fuyuki, he should have more than enough to not get tired with the feats he displayed in battle. Along with the fact that being in war will allow him a continuous supply of the evil, as well filling his reserves.
