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.

Iron Woobie: A vast majority of the cast. World War II does that to people. Though a notable example is Death, who has the most miserable job on Earth and still cares about humans.
