These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Critical Research Failure: Adolf Kamil tells Adolf Kaufman that in order to be a Jew, he needs to praise Jehovah. Even though Jews never use God's name. They usually write his name as "G*d". This is done to make sure that they never take his name in vain, so Kamil pronouncing it that casually is very strange.
Moral Event Horizon: A bit of an odd example, in that it's not the act so much as the character's later acceptance of it that qualifies. When Adolf Kaufman is forced to kill his best friend's dad as a "loyalty test", he's so nervous it takes three shots to do finish it and he gets physically sick after he's done. However, when he's able to keep on sending letters to Adolf Kamil and acts like nothing happened, you know the Adolf Hitler Schule did its job.
If anyone still needs convincing that Adolf is beyond redemption, following the Time Skip to 1944 he's shown rounding up and summarily executing German civilians suspected of anti-Nazi activities, and sending their children to concentration camps.
Values Dissonance: Considering it deals with the Axis Powers Deliberate Values Dissonance is heavily invoked, however one thing that smacks of the pure sort is Lampe's assassination of Hitler. The Nazi high command have grown to resent him so much they order his death despite the fact they know he's already suicidal and Lampe shoots him while he's already got the pistol to his head! To a Japanese reader, this scene would have a profound impact due to the tradition of Seppuku. From a Japanese perspective, robbing a man of the right to end his own life "honorably" seconds before he pulls the trigger is probably the cruelest way possible to kill somebody, definitely a fate worthy of a genocidal maniac. Most Westerners would probably see it as terribly unnecessary.
