I am actually OK with how the webtoon is changing the anti-japan hate from the novel. At the top, the politicians and top dogs are bad, which I guess is always true everywhere. But on the common man level, the Japanese citizens are just as good-hearted as anyone else, such as the old man and woman who wouldn't abandon the injured, or the soldier who stood fighting even though it would have been certain death. I think this is a nice view that doesn't wholly embrace Korea good Japan bad while still minimally changing the author's story.
