Personally I think what makes reformist Germany and Japan vs. good Russia a rather engaging and even tragic idea over rather than good china and Russia vs. evil former axis, is that essentially how it deconstructs the concept of a redemption arc for a civilization or culture. Which is why I prefer to have a Sablin vs. G4 rather than Russia vs. a bad Germany led by Speer, Bormann or Goering. It not just makes a story with a clear good guy and a obvious bad guy(normal germany) more greyer(due to reforms), raises the question: "
Have the evils of the past poisoned the well so far that even if a character, or a entire nation, is to gain redemption for their sins, that it dosen't really matter because everyone else will only remember what caused them so much suffering? Would such a redemption actually end up being bad for the world because of the victims that would be silenced?"
As someone familiar with Warcraft lore, this topic comes up quite a bit. Now Blizzard's writing is not really good even on a good day, but there is some food for thought
You have the efforts of the Orcs to redeem themselves after freeing themselves from the Legion often being shunned by the Alliance, and Jaina's dad seeking to destroy the Orcs because of their wiping out of entire human civilizations. However, it can also apply to those who didn't see the light due to how their lack of redemption is treated by the rest of the universe and even some WoW players due to how easy it is for WoW to build attatchment between player+faction. Specifically, the fate of Arthas Menethil, the most popular villain of the franchise.
Now whether Arthas is genuinely in control or not of his actions is a key factor in discussing whether he deserves redemption or not. Fans have been split on this issue in Warcraft. There are those, particuarly fans of a villain that's
arguably worse but was victimized by him as part of her backstory, who view him with utter contempt just because their Dark Lady do so too as evident in one of the Cataclysm cinematics where she recounts her past and Arthas victimized her.
They see Arthas as a spoiled brat who would have been a tyrant even without Lich King influence, who made every single choice by his own accord, with Frostmourne being less of something that controlled and corrupted his mind and more of something that just gave suggestions to a already depraved mind that was already present fully on display at Stratholme and when he burned the Ships in Northrend. They
even go as far as to view Arthas as the "rapist" of their favorite character.
On the other camp, there are
those that believe Arthas to be a well meaning man who wanted to do well, but whose personality issues may have led to his fall, but his worst actions after he got Frostmourne was not his own.: a flawed mind totally corrupted by evil. They view Stratholme as a necessary evil, while they view his actions against his own men in Northrend as something that while wrong, was caused by desperation.
A novel was written about Arthas life before becoming the Lich King, both sides only came out emboldened in their views on if he could have even been a good person or not.
Now if you want my view, despite being someone who legitimately thought Stratholme was justified, and thought Arthas to be genuinely well meaning, while keeping in mind his personality flaws and what he did(yet also finding the idea of consequentialism and total free will to make any decision very reductive itself). I will say both views are kinda reductive to be rather honest, but I see their appeal.
Now Arthas is not redeemed in Wrath of the Lich King. However, I will argue that the game did not settle the debate in favor of the "fuck Arthas" camp. The person who deemed him to be irredeemable was someone who found traces of his humanity and destroyed it because he believed there is nothing left to redeemed--yet considering
that character's backstory, and how he lost his entire family because of the Scourge, he really isn't one that can be convinced to see Arthas in a good light. Also consider that the half of Uther's spirit absorbed into Frostmourne says whatever sparks of Arthas humanity is left is keeping his dark half from destroying Azeroth, which hints that there was genuine good in him. When he dies he does express a sort of regret in asking the spirit of his father if "it's over" as if he had awakened from a nightmare. Yet that does not guarantee him a good Afterlife of being a blue smiley Force Ghost--for the
Other Half of Uther's soul that ascended to the Afterlife picks him up and drops him into the setting's equivalent of hell. This being despite the fact that the
closest figure the setting has to a literal race-supremacist Nazi, along with the fact that some warord that was namedropped in the latest expansion whom committed genocide on an entire planet were both sent to some purgatory after death where they could hypothetically be redeemed(or alternatively another sort of hell, but one closer to the Buddhist image of Hell as somewhere where people can move on from once they've atoned for their sins).
It could be argued that perhaps Arthas could be redeemed, but his atrocities and destruction of civilizations poisoned the well so hard that 99.999999999% of Azeroth wanted him dead and decided that
it wasn't worth it redeeming him because of the serverity of his crimes(that 0.000000001% dissenting opinion is quite literally one person: his long lost love, Jaina Proudmoore), and even when he died and regained his humanity, his actions will haunt him with someone he killed in the past preventing him from going to some purgatory or "temporary hell" where he could be cleansed of his sins and allowed to redeemed. This admittedly, is my view on the whole redemption thing and Arthas. It's a story where Darth Vader is not judged by Luke and the Force, but by the Rebel Alliance.
What do the Horde and Arthas have to do with TNO? Well in a sense, a "reformed" Germany wants to show to the world it changed. But what does it mean for those it once victimized. Can something like the KdN actually take off? Now, perhaps Germany can wash it's hands if Velimir or Rodzaevsky, or Shafarevich was the final opponent during the 2WRW, but it's more likely than not a less morally objectionable person and someone whom we'd find to be sane. In that case, is Germany's desire to change just cold comfort to the descendants of it's victims, and is it better that this whole project was consigned to the dustbin of history? The inevitability of the European theater of the great Eurasian War and by extension the Chinese theater brings this theme into light, especially in a war between two well meaning forces, but one victimized by the past evils of another.
