Abigail: So killing somebody, even if you have to do it... it feels that bad?
Will: [Beat] It's the ugliest thing in the world.
During an important part of the story, our hero, or just the character in focus, kills someone or something. This death could be popping his murder cherry, or it could just be one of the first kills he thinks is wrong. Even if it was self-defense and completely justified, he still feels guilt-ridden. He looks down in a My God, What Have I Done? moment, shocked at his hands because they just became accomplices in taking a life. Often this leads to a Heroic BSoD particularly if the hero is especially moral or idealistic. The act itself is usually part of a Batman Grabs a Gun Situation with the hero breaking a solemn vow that he swore never to break.
"These hands have killed! I've got blood on my hands, and I'll never be the same again..."
Could be followed by Out, Damned Spot!, but it doesn't have to be. This has nothing to do with washing one's hands of blood, metaphorically or literally — only with acknowledging the shedding.
This is a Sub-Trope to My God, What Have I Done? — the character in question experiences that guilt while staring horrified at his hands. If this trope is in a character's backstory, it's Sympathetic Murder Backstory. Compare Bleed 'em and Weep, where the character literally cries after taking life/shedding blood. If a character is contemplating their hands for an entirely different reason, usually drug-related, then see Contemplating Your Hands. If the character thinks what he has done is inherently wrong, he may become The Atoner. If he ultimately decides it was necessary, he may decide I Did What I Had to Do and, in darker settings, start his path down Gaining the Will to Kill.
As a Death Trope, expect the possibility of unmarked spoilers.

Eventually, he's forced to teach Rebecca how to fight but teaches her to do so without needing to kill. Eventually, when they're reunited years later, Kyros states how he's proud that despite his crime of forcing her to fight, her hands have still remained as clean as her mother's.
- In Sailor Moon, While she hadn't killed anyone at that point yet, during the S season, Haruka/Sailor Uranus looks at her hands and laments that they will become dirty after she and Neptune collect the Talismans from Eudial since the only way to get the Talismans is to rip them out of the hosts Pure Heart Crystals. Which makes it doubly ironic when it turns out the Talismans are inside her and Michiru's/Sailor Neptune's bodies the entire time.
- Subverted in Code Geass, where when Lelouch first uses his geass to kill the Britannian soldiers, he is stunned for a few seconds afterwards... before showing his evil grin for the first time, hinting at his Magnificent Bastard status.
- Later on, he does indeed talk about "These hands of mine"... All while wearing a malevolent smile and as a prelude to a maniacal laugh.
- In the Code Geass manga, Lelouch actually says this shortly after having a flashback to when he murdered Clovis. (In the same scene in the anime, he just throws up.)
- One possible interpretation of the consistent staring of one's Hand by Shinji Ikari is that he has committed a Sin in Neon Genesis Evangelion. Those Sins range from almost killing a Friend, willingly killing his Best New Friend, and the infamous hospital scene.
- In Mobile Suit Gundam Wing, Zechs Merquise ( aka Milliardo Peacecraft) liberated the Sanc Kingdom, but refuses to become the new ruler on the grounds that "his hands are stained with too much blood".
- Rurouni Kenshin says something close to the trope phrase in the opening to his super-long flashback arc about his first wife Tomoe, whom he had inadvertently killed some thirteen years previous as the climax of his career as an assassin. It's a major theme for a man who's been Walking the Earth as The Atoner for ten years when the series starts.
- Kenshin: This one's wife. Himura Tomoe, who was killed by these two hands.
- In the Death Note manga, after Takuo Shibuimaru gets hit by a truck as a result Light Yagami writing his name in the titular notebook, Light does this in a back alley. At first.

Along the way, she gets ambushed by a giant acid rain mutant monster. Pinned down and unable to run, she busts out her trusty revolver and unloads into the monster, after which her hands tremble violently and her breathing stagnates. This is especially traumatic considering not only that Sakura had previously been played up as a Friend to All Living Things, but this is the most violent thing that any rendition of Sakura had ever done, or ever would do again (barring the rest of the chapter / OVA).
- Also Clone!Syaoran when he realized that he had just killed Clone!Sakura.

- There's a moment like this in the Vagabond manga. Miyamoto Musashi, likely experiencing PTSD in the aftermath of his bloody attempts to become a famous swordsman, spends some time living with a peasant family. The peasants see him as a kindly big brother figure to the children, and at one point someone tells him that he shouldn't be so sad all the time, and he deserves happiness. Musashi responds by saying something along the lines of "How can I deserve to be happy when these hands have killed over 100 men?" The scene serves to show the difference between the younger Musashi, (who was a Glory Hound that never had a second thought about killing his opponents) and the Warrior Poet he is growing into, who is haunted by the blood he has spilled and the recognition that everyone he has killed had a family and loved ones.
- Jeremy, from A Cruel God Reigns after he kills his physically and sexually abusive stepfather via Vehicular Sabotage. He doesn't care so much about that as he does about the fact that his mother was also in the car. Oops. He spends the second half of the series trying to recover from a massive guilt complex.
- In a pre-afterlife flashback, Yuri of Angel Beats! stares at her own blood-covered hand, after she fails to prevent some sadistic burglars from murdering her siblings. She tries to bring the burglars a vase she thinks is valuable to calm them down, but breaks the vase and cuts her hand, leading to this trope. At the time, she thought that she metaphorically killed her siblings by breaking the vase; but the burglars probably would have been unimpressed by the offering anyway, and she eventually decides that she should stop blaming herself for their deaths.
- Guts of Berserk does this in the first Golden Age Arc movie upon killing Count Julius' young son Adonis, a kid who reminded him very much of...him.
- Balsa from Moribito: Guardian of the Spirit doesn't use the phrase directly, but her entire life so far has been about saving lives because she feels responsible for her foster father having had to kill six men (his own best friends, who were all members of a king's Praetorian Guard, to boot) to keep her alive.
- Invoked very hypocritically by Leonard Testarossa in Full Metal Panic!, when he tries to drive a wedge between Kaname and Sousuke by pointing out that the latter has killed over 100 people during his time as a Child Soldier. Leonard has actually caused many more deaths, but since they were indirect deaths (such as ordering his subordinates to kill someone), he acts like they don't count when stacked against Sousuke's active killings.
- Ange in Cross Ange has this revelation when she finds out that she and her squadmates have been killing human beings turned into DRAGONs all along. Especially for her since she personally stabbed a DRAGON with her knife repeatedly.

- In Unlimited Fafnir, Yuu finds out that his sister Mitsuki was forced to kill a fellow student after she turned into a dragon against her will. The camera occasionally focuses on her hands, or she'll look at them when saying that she'll kill Iris too if she has to. Fortunately, he stops her from having to do that, while also helping them to defeat the dragon attacking the school and coming for Iris.
- A big reason why Evangeline of Mahou Sensei Negima! considers herself to be a monster dates back to when she was first turned into a vampire and ended up killing her parents (along with everyone else in the castle) in uncontrolled blood lust.
- In Brave10, while trapped with Isanami after the fight with the giant snake, Saizou tells Isanami he's just a killer and cannot be anybody's shining knight.

Since then, she copes with the emotional weight of her actions, and it's not until she meets Kirito, who knows what it feels having to kill someone in self-defense or to protect others, that she finally begins to come to terms with it.

- The 1986 revamp made this one of its earliest key plot points in order to justify his Thou Shalt Not Kill policy rather than have one self-appointed right from the start (if you ignore the earliest point in his history where he was willing to go through with it). The Supergirl Saga had Superman forced to take lives of three rogue Kryptonians from another timeline who had slaughtered the entire population of their Earth, and subsequent writers right after such as Roger Stern and Jerry Ordway explored its aftermath and just how traumatizing the effects of performing such an act were for the Man of Steel.

A devout Muslim and pacifist, Dust was horrified and later struggled to wash the blood from her hands.

- In Child of the Storm, Thor and Loki responded to the human sacrifices of the Norse in the 10th century with revulsion and horror.

The death of Gyrich, on the other hand, was simple premeditated murder. Alex thought it necessary to protect Louise, but it still wasn't like the others: they were fighting back, if ineffectively. Gyrich, on the other hand, never had a chance.

- The Bible
- Pilate washes his hands to get the figurative blood of Jesus off of them. History lesson: it doesn't work. (The blood of the thousands of other miscellaneous threats to Rome he crucified, of course, are presumed to have come off easily.) Pilate's act was actually something of a Roman tradition, indicating that the official responsible for an act was not acting for himself, but rather in his official capacity. In other words, he wasn't trying to "wash his hands" of the Crucifixion, but rather saying (more or less): "I didn't do what just happened. That was the Roman State." Unfortunately for Pilate, very few non-Romans in that time and place understood the concept of separating the office from the person; it was quite the Roman concept, which didn't really translate for the mostly Jewish and Hellenistic Greek early Christians.

- When Dorian in The Picture of Dorian Gray murders Basil Hallward, blood-stains appear on his portrait's hands.
