The Soviet Union would still be a genocidal basket case, but it wouldn't hold the Ukraine (or at least as much of it as OTL) and possibly other territory it held so will have less people to kill by collectivisation and purge.
Sure, and German efforts to try and turn Ukraine into a colony wouldn't result in any unpleasantness.
Much depends on how Germany wins the war - if the war is won relatively quickly, with France knocked out in 1914 and Russia throwing the towel in during 1915, then I can well see Germany being a better overlord than the Soviets (though I doubt the Soviets would control Russia in this scenario - more likely after a short war it would be the liberals, the SRs or a combination of the two). But if victory somehow comes after Ludendorf and Hindenburg established their de facto dictatorship, the odds for an enlightened post-war Germany drop, as do the odds for a grown-up policy in the lands Germany took from defeated enemies, and there's even a chance that Imperial Germany turns into something every bit as awful as Nazi Germany (Ludendorf's ideas on how to run a country were a major influence on Shōwa era Japan and quite impressively depraved).
But then again, nothing is inevitable. The German conquest of Ukraine and the suppression of those nationalist groups the Germans took a dislike to would be a brutal affair simply because great power war is brutal by nature, but after the end of the war, there are multiple roads to both better and worse futures.
France wanting revenge. You might see a French version of Hitler in this timeline.
Heck no! France was too weak to go another round. You might get a French version of Franco, but a French version of Hitler wasn't on the cards.
Having lost two major wars against Prussia/Germany, and lacking the Junker class who were willing to destroy the country in their quest to deny "pacificism" an opportunity to take root, the main foreign policy plank of most French governments will be making nice with the Germans.
Plus, remember that even in Germany, Hitler faced significant obstacles to gaining power, and got ridiculously lucky both in terms of foreign and domestic events aligning to his benefit. Even if an alt-France had a nutter who was even more lucky than Hitler was in OTL, it's hard for me to imagine a Germany that managed to win WW1 at any point allowing France to fall into the hands of someone for whom "revenge on Germany" was a major policy platform. Especially when the other major neighbours of France have vivid memories of the last time a conquest-addict got to run France.
