There was a certain lack of morality required to do something like this, Harry thought.

Harry plays in the backyard while his mum watches.

Harry rests in a gilded cage. (LVxHP, mentions of past non-con, slight dub-con but otherwise completely consensual. Dark.)

The Dark Lord killed Albus Dumbledore. The Order of Phoenix fell. The rebels who didn't die, signed neutrality pacts for the safety of their loved ones. In the aftermath of the war, the Potter family fell apart. Harry grows from a happy child into a mostly-apathetic teen, to his parent's worst fear. (LV/HP. Dark/Death Eater Harry. p.s. bad parenting inside)

Harry Potter is sent to Hogwarts despite his mother's trepidation. He is, after all, a very abnormal 11 year old boy. It's going to be an era of personal growth and development, his change from a child into a wizard. Will he be what his mother fears he is, or what his father believes he truly is? (Dark Harry, Graphic Violence & Gore) (Sequel to Preemptive & Flower)

Tom kills to prove love won't change him. (Non-Graphic Gore)

Harry's family attempts to deal with his abnormalities. (Sequel to Preemptive, Part 2 of the Dark Triad AU)

Harry returns home from shopping, to deal with everyone's favorite Dark Lord. (Harry and Voldie friendship!)

One thing can make a serious difference on the outcome of any event, or even someone's entire life. Voldemort realizes Harry is his Horcrux in the graveyard that night in 1995 and decides he best bring the boy with him, instead of allowing him to return to the one wizard who might have the capability to destroy him. (Rated M because Voldemort gets a tad vulgar at the end)

Harry didn't know where he stood with Tom, or how to describe what they were. (Mentions of bloody sex, possessive behavior, and Harry is below 17)

Harry loves unconditionally. Like a dog. It's easy for Voldemort to begin to care for him. (Light Dom/sub, mentions of underage sex, non-graphic gore)

Voldemort surrendered to keep his final Horcrux, Harry himself, alive.

Tom owns Harry Potter, even if no one knows it. (Blood, possessiveness. TMRxHP)

Harry Potter works at Tom Riddle's candy shop in Knockturn Alley. (LVxHP, TMRxHP. Darkish story, mentions of dead bodies and torture)

Harry summons the Dark Lord Voldemort for a talk. It isn't the first time. (HP and LV friendship, slash if you squint real hard. 19 years later. Anti-HP/GW. Darkish!Harry)

Harry visits his family after hearing of his father's injury from the Daily Prophet. Supposedly. (Harry's a Death Eater, but he still loves his dad)

After a fight with his wife, James visits his son in his nursery. (Father-son bonding! Late Father's Day piece)

Voldemort came to Harry in the summer after his fourth year, knowing the Boy-Who-Lived was his Horcrux. Months later, at Hogwarts, Madam Pomfrey delivers life-altering news to 'unfortunate' Harry. (LVxHP, mpreg, multi-chapter, absolutely no german in this except for the title)

After being taken captive years ago, Harry enjoys his place at the Dark Lord's side. (minor character death, a wee bit of gore and torture, past mentions of rape and non-con, LVxHP)

Harry's chased up a tree on his tenth birthday by his obese cousin. Oh, also, he's got Voldemort in his head.
