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.
Stefan crosses it when he murders his uncle Grigor Borev to claim his title and then uses it to conscript thousands of peasants, burning their homes and driving their women and children into the forest (in Eastern Europe, in December) to die. The fact he talks casually about his men raping the women is icing on the cake.
Travers goes over when he admits cheerfully to his mistress Rita Skeeter that he was the one who loosed the Dementors on the muggle village to test their capabilities, and justifies it by pointing out they're only muggles.
The Dark Lord wins extra points for managing a Shout-Out during his MEH. 'Take her away, Lucius. We have never been able to abide the snivelling of women.'
This is after he announces he has no intention of honouring his treaty and saving Bulgaria, including Hermione, Viktor and Draco, and fully means to leave them to die.
The implication that Crouch Sr knowingly sent innocent people to Azkban because they knew too much about the illegal activities he was encouraging the aurors to commit.
The Dark Lord ordering Snape to sell Hermione to cement an alliance. The family is forced to pretend to be happy as they have a mock-wedding night (it makes sense in context) for the engaged couple, who are twelve and fifteen. Hermione sleeps with the doll that her new mother-in-law-to-be made her.
Draco and Viktor calmly discussing what will happen to the women if the castle falls to Pavel's werewolves and then agreeing to on a course of action. They're twelve and fifteen at the time.
Emmeline Vance's transformation into Eugenia Feathering Lestrange. Being forced to spy is bad enough, but to have to marry one of the people who tortured your best friend to madness? And then having to give him a child to keep your cover? It's even worse when one finds out that Emmeline/Eugenia was the one who found the Longbottoms, and Neville is her godson.
The fate of the muggles of Whitnell. The Dark Lord releases Dementorson them in order to test their effectiveness as a weapon, and then sends people to take pictures of the results.
Barty's revelation that he sometimes remembers what he was like. Imagine being mentally seven years old and having the occasional moment of realising what you've become, and what you did to get there, and being unable to understand it or put them it context at all.
Everything and anything to do with Voldemort possessing Harry. He goes through puberty. He is turned on by Hermione. Pass the Brain Bleach please.
If the notion of Wormtail having sex wasnít disturbing enough, the notion of having it with another rat definitely is.
The description of Tammís eye.
The Lestranges (and Sirius's) rotting, post-Azkaban teeth, and Wizarding dentistry generally. Why? Because rather than remove bad teeth, the medi-wizard simply uses what amounts to magical acid to melt the bad spot out and then rebuilds the tooth with new enemel. Reading about Sirius spitting mouthfuls of his liquified teeth into a garbage can is pretty awful.
The assassin who gets mauled to death by the werewolf children. The poor bastard was under the imperius curse and certainly didn't deserve to die like that.
You know how Snape won over the fangirls in Deathly Hallows with his tragic back story and constant love for Lily Potter? Now he has see Voldemort looking at him with Lily's eyes. He failed to protect her son. Dude needs a hug.
