Long post, I hope someone actually reads the whole thing.

I am assuming you mean more panels for each of the fights as I make this rebuttal. If they did that like Naruto and Bleach (particularly Naruto) we'd see in great detail what they're doing, but then we'd have like 4 whole chapters devoted to a single part of a fight (granted, there are some like that in Ares, but the one I'm thinking of is rather drawn out normally and quite long by itself). I'll take content over wasted panels and chapters if that was what you meant.

If by better illustrated you mean more detailed so you can actually see the strike instead of a line through the guy to show he's been cut in half, then I still haven't seen anything worth complaining about in the series. Generally speaking, Korean manga's aren't exactly rife with detail in the first place (of the three or four I've read) compared to certain Japanese manga serials. I think it fits the style, especially of Ares, who's blade is too fast to be seen by his oppenents, which is the whole 'wind' thing. [being vague, trying my best not to spoil and still give necessary details] It's no Berserk by any means, but then again, we get chapters of Ares more frequently than 2 weeks to 2 months. If this was what you meant, I see more clearly where you're coming from, but personally I have no complaints.

As for the morality issue, this is a manga about wars, there's a few chapters about Ares dealing with a normal person and what he needs to get done as a soldier that covers some of this, I thought extremely well, but it still doesn't change the fact that this is war. There's no honor in battles like these, it would be trite to say "I am your enemy, let us fight and the victor will let all his enemies go home." War is war, morality doesn't really have too much a place here. Granting mercy to ones foes only means they can come back and try to kill you again.
