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.
A lot of the villains, by way of the Tradition. Arguably the Tradition itself, though that seems to operate more under Blue and Orange Morality.
Yeah. What offends and angers the protagonists is that the Tradition just doesn't care. It has no preference for what the all-too-human characters want — it is just as satisfied with tragedy as with a happy ending, and it uses people, pressing them into the most convenient roles without any consideration for the lives they've tried to build up until that point.
