Tragic Villain in Literature.
- Dragon Bones has Garranon, whose motivations are noble (he wants to protect his brother), but who is ready to do everything for that goal - he openly admits that he would torture puppies to ensure the safety of his brother.
- Moby-Dick: Captain Ahab. While the whale can be seen as the villain, Ahab could be seen as the Tragic Villain: consumed by his own insanity, forced to chase the beast.
- Cujo isn't really a villain in the popular sense of the word, but he's just as much a victim as anyone else is, and if the Cambers had taken the possibility of their dog catching rabies seriously, the disaster could have been avoided. Parts of the books are told from his perspective; there it's shown that he suffers horribly from rabies and only attacks people because he believes that they are responsible for his pain, and worst of all that he was a genuinely nice and loving dog before being infected.
- Felidae has Claudandus: Once a normal, good-hearted stray cat he was later taken in by humans who just so happened to be performing horrible experiments on cats just like him, and had to endure more of them than any of the other cats involved solely from the misfortune of surviving everything the scientists put him through. Preterius, the head scientist's own descent into madness killed all hope of him ever being treated any better by his caregivers, and by the time he was free he could feel nothing but animosity towards people because of everything he'd been through, driving him to murder Preterius and start an insane plan to ethnically cleanse his own species to make them strong enough to overthrow humanity. Even in his last moments, Claudandus implies that he doesn't like what he became and looked back more fondly on the point of his life when he was still a good individual.
- Barty Crouch Jr. in Harry Potter and the Goblet of Fire. Due to his "Well Done, Son" Guy situation with his real father, Crouch Jr. came to see Voldemort as a Parental Substitute.
- Both Rhulad Sengar and his boss, the Crippled God, from the Malazan Book of the Fallen commit or orchestrate acts that cement them as villains, but both are also portrayed as deeply tormented victims of circumstance (a Jerkass Woobie and a Woobie, Destroyer of Worlds, respectively) and you really can't help but feel sorry for them.
- Claude Frollo from Victor Hugo's The Hunchback of Notre Dame suffers from his obsessive love for Esmeralda, which causes him to go tragically insane. What makes his suffering sympathetic is the fact that he was a deeply compassionate and caring man before he laid eyes on the gypsy.
- Mordred in some Arthurian interpretations, especially where (as some legends have it) Arthur tries to have him killed at birth as a threat, he's raised to hate Arthur by his mother, and hated in turn by Arthur's supporters simply because he exists, leading to the inevitable clash. It's hard not to sympathize with him in many cases given that.
- Francis Dollarhyde aka "The Tooth Fairy" in Red Dragon. Dollarhyde is a depraved killer who murders entire families, but during the course of the story makes a failed attempt at sanity, a normal life, and a healthy relationship. Unfortunately, years of abuse during his childhood twisted Dollarhyde's mind to the point where the "Red Dragon" persona eventually took over with nothing left of the decent, normal man that he had tried to be.
- Inheritance Cycle:
- Murtagh. During Eldest, he is enslaved by King Galbatorix and forced to fight on his side. Brisingr makes it appear that he's gone completely evil at first, but Eragon speculates that he's getting back at the world for giving him a crappy life. Near the end of the book, he's fighting the Dragon Rider Oromis and he desperately screams at him "YOU COULD HAVE HELPED US!".
- His dragon, Thorn, counts as well, as he wonders why he was brought into the world just so he could be tortured and destroy things.
- Galbatorix's dragon, Shruikan, is one of these as well. While Galbatorix remains a villain, several characters point out that Shruikan never chose to serve him; his real rider was killed when he was a hatchling and he was forced to bond with Galbatorix, driving him insane. When he finally appears in Inheritance, he is a nightmarishly huge and powerful dragon that appears to be an Omnicidal Maniac; Elva tells Eragon that nothing is left of him but pain and hate, and the best they can do is end his suffering.
- Goosebumps:
- The entire town of Dark Falls in the first book. They were all once a normal, thriving community, but an accident at the nearby chemical factory caused gallons of toxic gas to engulf the citizens, transforming them into vampiric mutants. Now, they have to feed on new visitors every year to survive. At the end, after the protagonists have destroyed most of the residents, the real estate agent responsible for ensuring new victims is the only survivor. The ending implies he'll continue his gruesome business, all alone.
- The creature from Frankenstein is driven to evil when everyone (including his eponymous creator) rejects him because of his monstrous appearance. In the end he tries to take his revenge on humanity before committing suicide.
- (Only in the book; the movie adaptation replaced all this with "Science Is Bad".)
- The Hunger Games: Just about any of the other career tributes. Yes, they are all ruthless and one even taunts Katniss about Rue's death but they are all teenagers being forced to fight to death in a Crapsack World.
- A Song of Ice and Fire:
- The ruthless Lord Tywin Lannister of is the most feared lord in Westeros. He is this because his father's weakness almost caused the fall of their family. The death of his wife (who was the velvet glove to his iron fist) also made it hard for him to raise his children with love and compassion, and led to his hatred of the child of this birth, Tyrion Lannister. Unfortunately, he has gone to another extreme, which made his children very screwed-up, and ended in his death.
- Prince Viserys of House Targaryen lost almost his whole family in a rebellion that toppled their dynasty and had to sell what's left of their riches so he and his sister Daenerys can survive. Drink and years of being treated as a joke caused him to threaten Dany in front of her husband Khal Drogo who then killed him.
- Theon Greyjoy was taken hostage as a child by Ned Stark after his father's failed rebellion. He betrays the Starks to earn his father's respect but can't because the man sees him as a "greenlander". With no one to back him up, Theon is captured, tortured and flayed and becomes "Reek".
- Gollum of The Lord of the Rings was a good person before being corrupted by the One Ring. After Gollum's death, Frodo still feels sympathy for him even though he betrayed him and Samwise.
