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.
Moral Event Horizon - Nevermind being a traitor, siding with the pirates and favoring the war - Ash's treatment of Jos was unforgivable in some fan's eyes
Most of what Falcone does... though it's arguable that he was a Complete Monster to begin with, and so does not even need to cross this line.
Nightmare Fuel - The torture scene between Falcone and Jos near the end of the first book drifts into this territory.
Squick - Pretty much everything that Falcone does that involves his proteges. Especially in Cagebird
