In one ending, Leasath commanding officer Diego Gaspar Navarro from Ace Combat X: Skies of Deception doesn't get caught and brought to justice, and while he fails to overrun Aurelia or sell his beloved Fenrir superfighters, part of his Evil Plan still plays out as the conflict gives a boost to Leasath's military-industrial complex.
Advance Wars Days of Ruin has the civilians, who pushed Isabella out of their group — and while their own survival was at stake, they should know long by this point that Isabella isn't selfish, but they never say anything about her being one of Caulder's "children" or that Caulder will bomb them to death if he doesn't get Isabella. They never get punished for it at all aside from dealing with the After the End setting that Will and company also have to.
Kimberly Freeman, the real sixth Lord of Chaos, counts as well. She was Brainwashed and Crazy, and after she is free from the Chaos tune that Drakath sang to her, she asks the hero if he / she wants to participate with her band, and they perform in the same way they were before being freed by him / her, this time with no Chaos tune controlling them and the hero performing alongside them.
In one of the endings to Amnesia: The Dark Descent, Baron Alexander succeeds in his master plan, thus completely getting away with manipulating and mentally torturing Daniel, betraying and torturing Agrippa, and killing god knows how many innocent people. In the other ends, Daniel may be considered this for those who don't consider his panic over the Shadow of the Orb and/or his aforementioned manipulation by the Baron to be adequate excuses for his own role in the Baron's ritual murders.
Saemon Havarian is only mildly villainous, but he's the most annoying character in terms of getting away with things. He keeps dumping his own troubles and enemies on you in both the original game and the expansion, and coming back and belittling what he did and acting like you're friends before doing it again, but you never get to take revenge successfully, even if you set the biggest thieves' guild in the country on him. Technically you can kill him and get his role later in the story to be replaced by someone else, it requires you being ready far in advance, making his comeuppance very tricky to do. The way he always gets away really fits the "Houdini" part — and in this case it's just not karma he's eluding, but a pissed-off player character as well. Considering that even beings of godlike status often fall to the might of the Player Character, it's about equally impressive.
A particularly grating example is Saerk. In Anomen's personal quest, his sister gets murdered, and Saerk is the prime suspect. If you convince Anomen to go to the authorities, they tell you that there's not enough evidence to convict him. The good option to the quest (as well as the one that will allow Anomen to be knighted and become considerably more tolerable) is to convince Anomen not to pursue Saerk and to let bygones be bygones. Oh, and it doesn't stop there. Sometime after Anomen is knighted, he learns not only that Saerk really was the murderer, but that now he's killed Anomen's father after the latter confronted him. Again, the good option is to convince Anomen not to kill him, saying that he'd be no better than his alcoholic father if he did. In summary, Saerk ruins Anomen's life, and the good option is to let him get away with it.
BioShock: All in all, the series generally gives chances for multiple Karma Houdinis, depending on the choices of the player.
Jack, the player character himself, if he has chosen to harvest all the Little Sisters, thereby turning him into an old-style Person of Mass DestructionPowered by a Forsaken Child, having killed about twenty little girls. The end of him? He becomes the king of Rapture, and uses it to kill the crew of a nuclear submarine, and conquer a nuclear weapon. And that's it.
Sander Cohen, the Mad Artist, that creates his sculptures using plastered bodies of men, and wants to create a masterpiece requiring the death of no less than eleven people, though hardly innocent. His comeuppance? That's up to the player/Jack. He can be killed, with possibly ounces of Karma if his picture is photographed, but Jack can just as well choose to abandon him alive in Fort Frolic, and later in Olympus Herights, in which case he makes it through alive.
Stanley Poole, the Mole in Charge turned Dirty Coward, whom was hired to infiltrate The Pature Family, and sell out Lamb to Andrew Ryan. Later it went onwards for him, as he degenerated into a walking Chronic Backstabbing Disorder, betraying all characters — Delta by giving him to Ryan because Ryan was suspicious, and having him turned into a Big Daddy, Eleanor for threatening to sell him out, causing her to become a Little Sister, and eventually killing the entire family by drowning Dionysus Park. You get the idea. In the end, it is the task of Delta to decide whether he lives or dies. However, one could say, that even if he lives, he is still left alone, trapped among homicidal splicers, so he might get his deserved comeuppance after all.
Delta himself can become one in the sequel, if he chooses to be a villain, although he might not get out just as scot-free as Jack, given he can only live on as the conscience of Eleanor, even if he does live on in her mind.
And finally, even Eleanor, the Distressed Damsel in the game, can become a Karma Houdini in the end. If Delta chooses to be a villain herself, she will become one, and harvest all the little sisters, kill her mother, and then as a final act, take Delta's survival instincts against his will, gaining his abilities, effectively allowing her to attempt to Take Over the World, with no punishment. Although in regard to her attempt to Take Over the World, the good ending of BioShock, and namely the ending of Minerva's Den, which is final, implies that at least her attempt fails, so she won't end up as the supreme ruler of all humanity. But no matter if she is a saint or a monster, she gets away scot-free.
Minerva's Den has only one ending so Subject Sigma/Charles Porter receives a happy ending regardless if he saves Little Sisters or harvests them.
Janos, the Prince of the Other World from The Black Heart. He is the one responsible for the corruption of the Other World, which was once beautiful, by causing endless wars to conquer lands that his father (the King, who was far too old and weak to stop him) gave willingly to others; he enslaved a species to be his soldiers, killed the King to gain his powers, framed Final when he stole the heart so Janos couldn't use it, wants to conquer all the other worlds through force and bloodshed, and ends up killing his own daughter, Ananzi, because she outlived her usefulness... and in the end, he succeeds in claiming back the Dark Heart, killing Final in the process, and acquires his father's powers. Another "The Bad Guy Wins" scenario in this case!
Yuna from Breath of Fire IV turned Elina into a monster, forcing her boyfriend to mercy-kill her, and is largely responsible for turning Big Bad Fou Lu into an Omnicidal Maniac. The game ends with him alive and well, and announcing his intention to do it all again. Apparently the creators meant to include his death in the ending sequence but ran out of timenote the game was rushed to production due to fears of a possible Capcom bankruptcy, and thus it looks like he never got his just desserts. In the manga adaptation, they also went with the ending as scripted in the game. Meaning Yuna is a Karma Houdinitwice over.
Gabriel Rorke survives his .44 Magnum bullet wound at the end of Call of Duty: Ghosts and captures Logan.
The villains of Catherine, Boss and Catherine, are both directly responsible for leading a number of men to their horrible deaths, and for causing a number of relationship breakups. Though Vincent does uncover The Boss's involvement and forces him to stop what he's doing should you clear the final level, both he and Catherine otherwise go on with their lives without any troubles, and in Catherine's case, it is possible to end up Happily Married to her.
Magus in Chrono Trigger. In one sequence, the player can be the bigger man and have Frog decide that killing him won't bring his dead friend back. While Magus can join your party at this point, no one ever thinks of asking if he can at least reverse the disfiguring curse he put on Frog. It may be that the only way to reverse the curse is to kill Magus, as only those endings where the heroes chose this option get this in the ending. Naturally he's not volunteering this option. However, the Playstation port has Frog turn back into Glenn regardless of what you choose.
The DS port retcons that Dalton was the one who turned Porre from the small town in Trigger to the imperialist superpower in Chrono Cross. Colossal Voodoo Shark aside, this means that on top of going from a humiliated loser to the ruler of a sovereign nation, Dalton is also responsible for all the bad stuff Porre got up to - including destroying The Good Kingdom and killing a good chunk of the original game's cast. Being that Dalton doesn't even appear in Cross, needless to say, this plot point is never followed up on, so as far as the story is concerned, Dalton likely spent the run of Cross lounging on a throne and eating grapes.
Command & Conquer: Tiberian Series: While it's true that canonically GDI won in three Tiberium wars, Kane evades death, outliving his enemies (such as Havoc and McNeil) and his Brotherhood of Nod continues to stand and wait for his return. It seems he has a Xanatos Gambit where he had forced GDI to fire the Ion Cannon at Temple Prime, causing a liquid Tiberium explosion that attracted the Scrin to Earth, had the player commander use the Liquid Tiberium Bomb which caused the Tiberium infestation to worsen so he can have access to the Scrin technology including the portal tower and had given the Tacticus to GDI so they can contain the Tiberium. All of this is for his plan for ascension which he achieved at the end of Command & Conquer 4: Tiberian Twilight in both sides and with all the Tiberium contained, he's seen as the Messiah and never gets punished for starting four of the bloodiest wars in history.
Don Weaso in Conker's Bad Fur Day. He massacres several dozen Uga Bugas with Conker's help, kills one of his servants (Paulie), then later betrays Conker for cash and murders Berri. Weaso's fate, he gets to run off safely with his ill-earned money. In comparison, the Panther King and Ze professor suffer Karmic Deaths, and Conker is punished for his greed and frequent sociopathy.
The antagonist of the second Dark Parables game spends his time capturing people who wander into the wrong part of the Black Forest of Germany and turning them into frogs. His "punishment" at the end of the game is death - which is the very thing he's been wanting for centuries - and a spectral reunion with his beloved first wife. It's bittersweet and very beautifully done, because he's an Anti-Villain rather than a full-on bad guy, but still.
When your characters in Darklands become imprisoned, they may may be ask a priest for help and be released, if only their Virtue is high enough. This happens even if they put into a prison for slaughtering dozens of city guards.
In the Dawn of War Expansions, Warboss Gorgutz constantly loses to the enemy army but when backed to a corner always has an escape plan and manages to get off the planet while his army is getting killed by the enemy.
Jitterbug, the Big Bad of Cave shooter Death Smiles, is a pretty strong example. He's directly responsible for the demons rampaging throughout Gilverado, as he had been opening portals to the demon world with the intent to create a portal back to the real world. In the end he is not punished for his actions, nor is he repentant in any way. He gets exactly what he wanted, and is allowed to leave for the real world, where he can go back to being a cold-hearted Corrupt Corporate Executive. The only bad thing that ever happens to him in the entire game is getting eaten by a Giant Space Flea from Nowhere that came out of one of the portals he'd opened. This does not kill him, and depending on the version you're playing, and depending on how well you've done, it may only pisshim off.
The sequel does show a bit of comeuppance: in Deathsmiles II's True Final Boss sequence, he gets inadvertently yanked back into Gilverado and is beaten up yet again by Dior's Angels. Given that he hates Gilverado, being trapped there once again is definitely a punishment for the guy, and his chances of escape are next to nil this time, given that he can only open the portal on All Hallow's Eve and the Angels are probably going to make very sure to keep an eye on him around that time.
Double Switch: Elizabeth is very much a Karma Houdini. Why? Because she took a hefty bribe from mobsters to let them find Brutus, and she had to have known that they were going to murder him, one of her own tenants. She did not try to protect the tenants from a secret society, mobsters, and Eddie. In fact, she actually prevented two tenants from leaving the building when they were trying to escape Eddie. No one chews her out for her actions, not even at the end of the game.
For all its emphasis on Grey and Grey Morality, Dragon Age: Origins loves to pit the PC against some truly despicable bad guys (Branka, The Tevinter Slavers, Bann Vaughan) and give the PC the option of letting them go on with their evil business, usually for some money or a nifty bonus. For all of BioWare's emphasis on story arc and character, they know the marketing value of Video Game Cruelty Potential. There are some exceptions to this: There's Frandlin Ivo of the Dwarf Noble origin. As part of your younger brother Bhelen's Batman Gambit to become king, he has your older brother Trian killed either by his own hand or by you. He then convinces your companion Frandlin to betray you and either lie or snitch about you killing Trian. And for his treachery, he's promoted to being Bhelen's right hand man. And if you decide to make Harrowmont king instead of Bhelen, Ivo conveniently disappears.
Isabela becomes this after the events of act 2. Her selfishness forces the Qunari to stay at Kirkwall for years, causing numerous conflicts between them and the inhabitants of the city and ultimately leading to a full-scale war that kills hundreds if not thousands of Kirkwall's guards and citizens. Even when there was still time to prevent the conflict, Isabela stole the object of the Qunari's mission and ran off with it. Even if she comes back later and turns it in to the Qunari Arishok, it's too late to undo the damage. And no matter what choices are made, she never gets any kind of comeuppance for the ruin that she caused (if she is handed over to the Arishok, she simply escapes their boat two days later).
Hawke, the player character, can become this during the quest Night Terrors. By selling out the young, inexperienced Feynriel to a demon the player is granted a fairly useful stat boost. Feynriel will become an abomination and, while he kills many people, it all happens off-screen and none of the victims have any relation to Hawke. Its especially noticeable since Merrills story arc constantly reinforces how dangerous and foolish consorting with demons really is, but Hawke will get away scot-free with their reward intact.
Also, the hero's childhood friend comes Back from the Dead in the ending, but not anyone else of the party.. Apparently to justify the above.
But the true Karma Houdini is actually the Zenithian Lord. The overgrown lizard who kills your father and makes your mother an outcast prisoner for the crime of falling in love and fathering the hero who would save the world, yet these actions are completely ignored.
Downy Reed'sFreudian Excuse involves one of these. A local noble forced young children to fight their siblings to the death and he was one of them. When he grew up, he swore he would take revenge, but the noble had died peacefully in his sleep surrounded by friends and family. Without any way of coping with his loss or even feeling like his enemy had met a just end, he instead decided to remake the world so that such things could never happen. Failing that, having no world at all would be better.
During Mia Touma's route, she takes a turn for the yandere and first more or less rapes her brother in his sleep with drugs. Following this, she tries to get her 'rival' Lily petrified and then wants to leave her to die. After she has her own Disney Death sequence, she pops up under mind control on the enemy side. The mind control is broken, but then it turns out she's still on their side and her yandereness has increased, after which she kills thousands of people, formally betrays her former allies, and in the end nearly destroys the world. In the end, she not only doesn't even get a slap on the wrist, she gets to have her memory of these events wiped so that she doesn't have to remember she did anything wrong. As a point of justification, her lover is the world's hero, so his influence may be responsible for getting off without punishment.
Porky Minch from Earthbound. He kidnaps little girls, steals your helicopter, and ultimately you fight him alongside Giygas. And when you finally stop his villainy? He teleports away through time, and you don't see him again until the sequel, and there he's not any less of a Karma Houdini there, either. He spends his entire life corrupting the world in an effort to make it more fun for himself, using advanced technology to live a sort of toy life, but never really gets taken to task for it. He ends up sealed inside his Absolutely Safe Capsule, which will keep him alive and unharmed for eternity. It's supposed to be a variant on And I Must Scream, but he seems happy enough with it in the end; being so desperate to prolong his own childhood, gloating about escaping punishment forever and being protected within the safety of an artificial womb isn't really all that bad, or even all that different from the way he was living before.
Vivec in Morrowind. While not an outright villain, he and the two other members of the Tribunal very likely betrayed and murdered the ancient hero Nerevar, then went against the wishes of Nerevar's patron deity (Azura) by using the Heart of Lorkhan to become gods and rule over Morrowind for some 4000 years. After Dagoth Ur's defeat at the hands of the Nerevarine and the deaths of the other two members of the Tribunal, Vivec was put on trial for his past crimes. At his trial he confessed to the murder of Nerevar but claimed that he couldn't be charged with it because the divine and mortal versions of him are different people. He then asked the court to summon Azura to speak on Nerevar's behalf, and once they acquiesced to this he then bound Azura to their plane of existence and shoved his "spear" down her throat before vanishing. His disappearance also leads to the destruction of Vvardenfell and the downfall of the Dunmer people. After some temporary measures fail, the Ministry of Truth (a moonlet hurled at Vivec City by Sheogorath in the distant past which Vivec froze in place using his divine power) crashes down with its original momentum, destroying the city and causing Red Mountain to erupt. Much of Morrowind is covered in choking ash, and many of the still habitable southern areas are conquered by the invading Argonians. If he is to be believed, he has also achieved CHIM, meaning he is now something far above and beyond punishment for his crimes.
You! Yes, you, in Oblivion. Doesn't matter if you are the leader of the Thieves' Guild and the kingpin of all crime, an assassin for the Dark Brotherhood who has committed a series of cold-blooded murders across Cyrodiil, someone who has done every dark and dirty deed for the various Daedric Princes, or a bloodthirsty psychopath who kills people indiscriminately in the streets, at the end, you're still hailed as the hero and savior of the Oblivion crisis. Even better, with the Knights of the Nine expansion, you can easily wipe out all of your Infamy just by doing a pilgrimage to nine wayshrines. Even the gods forgive your crimes!
If the player exterminates the Dark Brotherhood, Babette will not be present in the sanctuary. This is due to the fact that as a vampire in the form of a young girl, she is subject to the Improbable Infant Survival of the game... even though she's not even remotely a child at all. The same goes for Cicero, who chances are you'll never even meet.
Another case of Karma Houdini is Maven Black-Briar, the crime queenpin of Riften. Not only is there no questline that involves taking direct action against her, as an "Essential" character she cannot be killed without the use of console commands, glitches, or mods. To take it even further, if the Imperials take Riften then she gets appointed Jarl and says the title's only a formality to her since she's always been in charge anyway. Similarly, unlike the Dark Brotherhood, there is no way to deal with the Thieves Guild as almost all the important NPCs of the guild are similarly Essential and immortal.
The Black-Briars' equivalent in the Reach, the oppressive Silver-Bloods. It is possible to undermine them, but that involves letting Madanach, king of the Forsworn(who are just as bad as, if not worse than, the Silver-Bloods), go on a killing rampage in Markarth, resulting in the death of (among many others) Thonar Silver-Blood (Although since Thonar's Essential Status ends after you escape his prison even if you do kill Madanach for him, there's nothing stopping you from cutting him down the second the quest ends anyway). And there is almost-nothing you can do about his thuggish, politically-inclined older brother Thongvor, who will become Jarl if you side with the Stormcloaks. You can, however, have "Jarl" Thongvor and his henchmen exiled to Windhelm as traitors for the rest of the game, if you first cede control of Markarth to the Stormcloaks by peace treaty in "Season Unending", then later retake the hold for the Imperials.
Most glaringly, the Aldmeri Dominion. Yes, you can kill a few Thalmor notables, but you can't actually do anything to slow the Dominion's ambitions down, except insofar as winning the civil war qualifies. Even winning the civil war may not be enough to stop the Dominion, as their ambitions extend far past Skyrim alone and the extent of the Stormcloaks' ability to defend Skyrim from them is up for debate.
The premise behind Ensemble Stars! is that the previous year, a number of students orchestrated a War between themselves and a number of other eccentric students which allowed the Student Council to take control over the school, bringing about a dark age that only Trickstar could overturn. It's also a card-collecting ensemble gacha game where every character is ultimately treated as sympathetic and lovable. The bad actions of some of those characters (plus a couple who did arguably awful things unrelated to the war) are usually only fully revealed in Reminisence story events, and some of them have hurt other characters very very badly. However, as the audience never really sees any kind of in-depth redemption, and as most of the characters don't really suffer any serious consequences based on what they did, many players consider some characters to come under this trope. The most commonly cited is Eichi who was the ringleader behind it all but not only fails to see any breakdown in his relationships (in fact, the guy he took down despite admiring him so highly actually asks to become part of his unit and soon considers him a close friend), the in-universe general public never finds out so he remains the leader of the top idol unit in school apart from Trickstar. However, he does regret his actions and also incidentally has a genetic chronic illness meaning he has always been expected to die young, so his life isn't all pearly either.
Olympia, from Etrian Odyssey 3: The Drowned City. This is the person who was responsible for the deaths of countless adventurers in order to keep the Deep City hidden. In addition, she tried to kill your own party on at least two separate occasions. In both the Deep City and True endings, she gets away scott-free with absolutely no ill consequences whatsoever. In the Armoroad ending, she gets beaten down alongside the final boss (Abyssal King Seyfried), but gets better in the post-game.
In Fable I, you can absolutely be the most evil mofo Albion has ever seen, and you can bathe the Sword of Aeons in your beloved sister's blood to awaken its unstoppable power. You will suffer no consequences for your actions.
Reaver from Fable II. When you first meet him, he seems like a pompous yet somewhat awesome pirate king. Then he asks you to do a little favor for him: secure a sacrifice to the Shadow Court so that he can remain young and beautiful beyond his natural years. It's a choice between making some poor young girl who got lost the sacrifice or willingly giving up some of your own youth and beauty. You can't kill him, though, because he's necessary to take down the Big Bad.
And the above is just the tip of the iceberg. Reaver is personally responsible for the demise of Oakvale, and was busy selling the protagonist to the Big Bad while he/she was off performing the aforementioned favour. He also kills off a certain comic relief character, though that might count as an act of goodness to some.
He returns in the third game as a highly successful Corrupt Corporate Executive who owns environmentally disastrous factories that run on child labor. Not only does he avoid comeuppance, he usually ends up making a profit somehow whether or not you agree with his decisions. In all probability, he's been rolling like this for three hundred years.
If you read the note from him after the game, which is narrated in his voice, he simultaneously mentions something he has to do alone. Presumably make his offering to the Shadow Court for more years, though his voice indicates he's growing tired of it.
Sam and Max Spade, who repeatedly misuse a highly dangerous necromantic tome and summon undead monsters that proceed to kill innocent bystanders. The brothers aren't intending to cause trouble or get people killed, but it frequently happens and they never learn, nor are they ever punished for the lives lost.
Invoked In-universe in Fallen London: A certain storyline requires you to cap off your career as the Empress' Court's artist-in-residence by creating something so offensive and/or awful it gets you exiled, and kicked out of the court permanently. One of the options is to write a tragedy with an utterly horrible one of these: He gets to ruin the protagonist's life twice in a row, deprive her of lover and money, permanently kill someone and get off scot-free at the end just for the shock value. It works almost too well, as you barely escape a beating by the royal guards.
Iguana Bob in Fallout. He runs a stand in The Hub selling what he claims to be iguana bits and iguana-on-a-stick but in reality is human flesh from corpses he bought from Doc Morbid in Junktown. The player can kill Doc Morbid with no problem, but attacking Bob will most likely result in everyone in town shooting at you. Originally there was the option to report him to the police, but this was Dummied Out and removed dialogue implies he eventually escapes. The player can still blackmail him with the threat of doing so and get paid for their silence, but there's no way to make him stop altogether. In the sequel his son takes over but it's unclear whether he shares the same ideals as his father.
Depending on the player's choice at the game's ending, Pagan Min can be spared by Ajay and allowed to flee the country in a helicopter, though this can easily be defied by shooting Pagan in the first place (or alternately, shooting down his helicopter before he can escape).
Much to the dismay of everyone who bought Far Cry 5, there is absolutly no way to defeat Joseph Seed. He will always win no matter what ending you pick, leading to a severe case of both Cruel Twist Ending and Ending Aversion.
Genesis in the Final Fantasy VII franchise, who manages to get away alive, and ends up still running around doing whatever... after killing everyone in his hometown, even his own parents, turning the people who defected with him into monsters, and starting a completely pointless war. For no other reason than to lash out at the world for something that was mostly his own fault to begin with. Also, betraying his friends, and then trying to cynically use them, which ended up as the last straw that broke Sephiroth's sanity.
The Turks in the original game, especially Reno, who destroyed the entire Sector 7. In Advent Children he's demoted to comic relief.
Final Fantasy XII: The entire nation of Archades. It expanded by dominating and oppressing its neighbors. Its punishment at the end of the game? Nothing.
Final Fantasy Tactics has the Church of Glabados, who get away with hiding the truth that the saints they worship are actually Demons responsible for much of the strife in the game. They even kill Orran Durai, one of the few good guys left after the war, as a heretic, because he published a paper detailing the truth of the war. It takes 400 years before the truth is exposed.
To a much greater extent, William Afton, note or if you prefer, Purple Man who murdered at the very least five children. Despite everything he's done, and because he framed an innocent man for the crimes and that he always covers his tracks, the police never caught him and he went off scot-free.Eventually revoked in the third game, where the souls of those murdered children finally get a hold of him, giving him no other option than to run into the Spring Bonnie suit he used to murder them. This leads to him becoming Springtrap 30 years later. Invoked further in the final game where he is finally killed in a fire deliberately set by someone implied to be his old business partner, and whose daughter he killed.
In Freedom Fighters, the Big Bad, General Tartarin, actually does get his comeuppance midway through the game. He is replaced by The Mole, Colonel Bulba, who betrays your organization, has your allies killed/captured, and tries to have you taken out (it's implied he sent you to kill Tartarin so he could grab all the glory). But you never get the opportunity to put a bullet in his brainpan.
One appears in the first Golden Sun. The "evil thief" Dodonpa, who kidnapped a wealthy merchant with the intention of sending repeated ransom demands and who is trash-talked by most people in the village he runs, appears in a sidequest in which he sics a monster on the heroes, then is trapped under it when he tries to stab them in the back while they're distracted. His ultimate sentence is to replace the merchant in his dungeon cell, to which his underlings have a key, and receive no treatment for his twisted ankle.
A less serious case is Briggs, one of the main antagonists in the second game, battling Felix's team, stealing Plot Coupons, and having his grandmother sic a boss on them. He doesn't get a proper hint of redemption until the third game, where he aids Matthew's party into fleeing from Belinsk, losing his life in the process. And up until them, he had been keeping up with the pirate trade.
The Grand Theft Auto series plays a lot with this trope, especially with the playable characters, including: Tommy Vercetti in the mission "Missing With The Man", killing civilians and causing destruction in the city, CJ in "Management Issues", killing the Madd Dogg's manager and his girlfriend, and Toni Cipriani having committed a lot of atrocities on orders from Donald Love and Ned Burner. And of the three mentioned, they all got away with it.
GTA: Vice City has, besides Tommy, Maude Hanson. Despite currently being allied with the Vercetti mob, she's a mentally unstable psychopath who allegedly ran a children's home. Unfortunately, she's the biggest child hater imaginable; even Vercetti is disgusted by it. Maude is even being investigated for the VCPD.
Donald Love. Consider: sent Toni to steal corpses for "his party" and bombard the Fort Staunton sector (probably killing thousands of innocent civilians). While his fate is unknown at the end of GTA III, still qualifies.
The King Courtney from Grand Theft Auto III. Besides being quite hostile with Claude, he betrayed him and allied with Catalina and never received any punishment.
While his compatriots Michael and Franklin aren't straight-up good guys by any means, Trevor Philips, one of the three Villain Protagonists from Grand Theft Auto V, probably would have been written as an antagonist in any other installment in the series. In addition to being a cannibalistic Serial Killer, he also relentlessly abuses and finally kills the innocent and helpless Floyd Hebert. But in Ending C, he gets to walk off triumphantly into the sunset just like the other two, although he does burn to death in Ending A. However, picking A or B does leave most of the other villains in the game to walk off scot-free, so in the end it's a matter of picking your poison. And frankly, compared to Steve Haines or Devin Weston, Trevor is pleasant.
Jock Cranley in GTA V. He literally got away with murder after throwing his wife Jolene off a cliff and causing her ghost to haunt Mount Gordo, scaring unsuspecting hikers. He was arrested, but was immediately released and later became rich and famous. He was even allowed to run for governor and got away with throwing feces at his rival's campaign headquarters. (They're both terrible candidates, but the point still stands.)
Halo: The SPARTAN-II and III programs may have saved humanity from the Covenant, but the Spartans were actually originally designed to fight other humans. Not only that, they were kidnapped/recruited from young children, and were sent to the field by their early teens. However, the only person who's ever held responsible for all this is the chief scientist of the SPARTAN-II program, Dr. Halsey. Everyone else at ONI, including the very people who approved of everything Halsey did, namely ONI head Parangosky, has gotten off scot-free. In HUNT the TRUTH, Benjamin Giraud tries to reveal the horrible truth behind the Spartans, but ONI successfully smears him as a liar and then quickly captures the other journalist who tries to carry on Ben's work. Not only that, but ONI later attempts to undermine UNSC foreign policy by sabotaging their closest non-human ally, the Arbiter. Once again, ONI has suffered no personal consequences from this, despite their foolishness being partly responsible for the rise of powerful anti-human Covenant remnants.
In the Perfect Crime ending, all of the heroes and witnesses are killed or otherwise incapacitated and all evidence is destroyed. The game concludes with the complete and utter triumph of the Origami Killer.
Lieutenant Blake is a real nasty, brutish thug of a cop. He flaunts his authority as an excuse to do whatever he wants, and throughout the game, his go-to tactic for interrogating suspects is kicking the crap out of them to the point where he almost kills several. In the climax, he even gives a sniper a direct order to kill Ethan (who's innocent), even if he comes out peacefully with his hands up. If Ethan is killed by this sniper and Shaun survives, Blake is suspended pending an investigation, but he is not fired or imprisoned. A possible aversion happens if Ethan survives while Jayden dies, as it is implied that Jayden will haunt Blake through the ARI and cause him to succumb to the same addiction that crippled him. However, this is never made explicitly clear.
Gordi Kramer is even more despicable than Blake — while Blake is at least motivated to be an asshole by his honest desire to stop the Origami Killer, Gordi is a multimillionaire Psychopathic Manchild who idolizes the killer and actually drowned a young boy in an attempt to be like the killer. In his short appearance, he shows himself to be an unrepentant asshole with a callous disregard for anyone other than himself. While his father Charles has his staff gunned down, is brutally beaten, and can be left to suffer a heart attack, Gordi is never even mentioned in any ending and he presumably gets away scot-free.
Morcalavin in Heretic II, the villain of the story. One of the Precursors, who botched a spell to make his race Ascend to a Higher Plane of Existence and became a power-mad Evil Overlord creating a plague that turns people into rabid zombies or mind-controlled slaves. At the end of the game, you learn that the way to rid the world of the plague is to fix the spell, allowing Morcalavin to become indeed a god. Even though he's magically cured of his madness, it's still a bit annoying that he is rewarded rather than punished for his crimes...
In Horizon Zero Dawn, it's found out that one man from the past is the root of just about ALL the problems in the world. The world used to be very technologically advanced. Then Ted Faro, through his company Faro Automated Solutions, created robot soldiers that went haywire and wiped out all life on the planet. Faro also deleted the sum of human knowledge after deluding himself into thinking that knowledge will just lead to the same mistakes. Despite all this, he was able to live out the rest of his life in Thebes, a bunker with provisions and amenities insulated from the robot soldiers he produced and the toxic environment they left behind.
The Komato in Iji. They commit genocide of one entire alien species, attempt genocide of another (humans), and guess who dies? The one who repented.
The Poacher in Jade Cocoon. You're told early on in the game that only Nagi women can purify cocoons to make the minions inside obey their master, and these women only do so for a cocoon master. The Poacher's just that: a poacher, so that means he literally has a Nagi woman held hostage and is forcing her to purify his cocoons for him. Koris even tells you this is what poachers do at the very beginning of the game. However, even though you fight him three times, Levant literally just lets him run away each time he beats him.
You! Yes, you, in Jade Empire. It's entirely possible to spend the first 99% of the game breaking people, hurting things, framing innocents, helping slavers, kicking puppies (you can actually kick puppies if you're evil enough)... and then at the very end of the game, decide that godlike power isn't worth dooming the world to a slow, lingering death. Your alignment shoots up to 90% Good, all your allies forgive you (even though you've magically bound them to your will), and everybody lives happily ever after. Except Wild Flower. Because you shattered her mind. To let a sadistic demon take it over. You horrible bastard.
Not only that, but considering the Way of the Closed Fist is more about "facing one's challenges head on, challenging one's station in life, and working to become self-reliant" rather than just being evil, it's entirely possible that you decided to finally kill the Water Dragon, thus screwing over the land's water supply for all the wrong reasons.
The Edutainment Game series Jump Start had a spin-off series of workbooks. In one of them, JumpStart 2nd Grade Math Workshop, C.J. and Ratso are competing in a tournament, but they sorta break off in the middle so Ratso can kidnap the princess, whom C.J. rescues. Ratso gets absolutely no consequences for his actions and no one seems to mind. They just resume the tournament and act as nothing ever happened.
In Kid Icarus: Uprising, Viridi is never actually fought for having slaughtered thousands of humans and laughing about it. You do fight her forces and destroy many of her bases, but she herself never gets punished for it. It becomes more aggravating when she doesn't even admit that her fight against Hades brought an alien invasion into the world to ransack the earth. The only thing that keeps it from truly being aggravating is the fact that she spends all the arcs after hers helping Pit fight the various other threats running around.
Kirby Super Star has Captain Vul. He makes sure the piloting of the Halberd runs smoothly, but when Kirby invades the Halberd, Vul becomes violently obsessed and will do anything to kill him — even destroy his own ship. After Kirby destroys the reactor, Vul panics and decides he would rather live than go down with the Halberd. He is the first to evacuate the doomed airship, and is never seen again.
Most of the characters who travel with you are Light-sided but will mostly only be slightly annoyed if you decided to kill random innocent beings for no reason. Juhani, Carth, Mission, and Jolee turn against you if you finally declare your intent to take over the entire galaxy, but up to that point, you get away with murder.
If you do choose the Light Side ending (even if it's for all the wrong reasons), you turn light sided. Apparently slaughtering your way through everyone else in the game is cool as long as you really want to beat the crap out of a traitorous party member.
This is taken even further in the sequel game and various peripheral media. Regardless of whether or not the player indicates their character took the Light Side ending in the last game, everyone speaks of him in the most glowing praise conceivable as having done no wrong before, during, or after the events of the first game.
This has been scaled back significantly in the lead-up media for Star Wars: The Old Republic, in particular Revan. There were some significant consequences as to Revan's actions both during his redemption and after he married Bastilla, putting him into a far weaker position when he hunted down the Sith Emperor.
Roy Earle, the JerkassDirty Cop of L.A. Noire, has reported Cole's affair with Elsa to the media, and gets away scot-free. He is later seen in Cole's funeral pretending to be his friend, much to Elsa's outrage. For this information, the corrupt players in the Suburban Redevelopment Fund — a cruel con to offer housing for war veterans and then make a ton of money when a freeway is built through the development area — make him a member of their scheme. A lot of people die for this, and most of the men responsible are arrested, but Earle manages to completely evade the axe.
The Gerudo Pirates in The Legend of Zelda: Majora's Mask kidnap Lulu's children and murder Mikau (who was implied to be the father) after the Skull Kid convinced them that they were the key to entering the Great Bay Temple. Link goes to rescue Lulu's eggs but at no point can he kill any of the pirates, only knocking them out or defeating guards in battle and causing them to run away.
At the beginning of The Legend of Zelda: Skyward Sword, Groose and his two goons attack and imprison Link's Loftwing so that he wouldn't be able to participate in the race that determines who gets promoted to senior class in the Knight Academy. When that doesn't work, they still cheat during the actual race, despite having been explicitly told that interfering with other competitors is prohibited. And yet, as far as anyone can tell, neither Groose nor Stritch get in any kind of trouble for the things they did. note Eventually, Groose redeems himself later in the game, while Stritch is actually a nice guy when Groose isn't around. Cawlin later suffers a subversion: He asks Link to deliver a love letter to his crush, and you have the option to deliver it to a ghost needing toilet paper instead. Either way, it doesn't work out for Cawlin and he spends the rest of the game heartbroken (and the ghost reads the letter first and starts stroking him lovingly in his sleep, giving him nightmares if you give it to her).
Liar Jeannie In Crucifix Kingdom: The normal endings of this game all require the player to kill the Cadaver Queen, a despot who treats humans within her kingdom like cattle. The secret ending has the player fight a different Final Boss in order to escape the city. While the protagonists found a more personal victory in finding freedom, this ending also means the queen is still in power to continue her atrocities.
Recurring Boss Vanessa from Luminous Arc is set up this way, constantly being asked to join the other Witches permanently after a handful of Enemy Mine encounters, despite having killed who-knows-how-many human researchers on her solo quest for Plot Coupons. Also, it gets subverted when when her rather complex motivations are spelled out. The deaths attributed to her turn out to be due to the project they were working on going out of control. Vanessa was in the right place at the right time and simply took off with the Lapistier during the chaos, and the Church pinned the deaths on her in propaganda. Vanessa forced her fights with the protagonists since she (correctly) assumed the human party calling the shots was too full of Fantastic Racism to hear her version of events and would have fought her anyway, and resented the other Witches for being passive enough for things to get as out of hand as they did. Proven innocent and with the Witches pushed into action, she has nothing to apologize for and happily joins.
You can let a number of NPCs get away scot free for various crimes. However, occasionally this will work out for the better. Helena Blake, a crime lord from the first game, asks you to kill two rivals for her and then return to her base for the reward. You can either take your credits, arrest her (she resists and you have to kill her), or convince her to disband her gang. If you ask her to disband it, she turns up in ME2 working as a social worker on Omega. If you don't, she ends up working for Aria. Similarly, Rana Thanoptis, who was working on indoctrination for Saren in the first game, turns up in Warlord Okeer's base on Korlus, ostensibly to help the krogan. She's not too successful.
Balak, in the paragon route for the "Bring Down the Sky" DLC. The only way to save the people he's threatening is to allow him to escape. Worse, it's revealed in the second game's news feeds that the son of a bitch is STILL at large. If that fact is not a huge kick to the gut for Paragon players, I don't know what is...
Vido Santiago in Zaeed's loyalty mission. The man who stole the Blue Suns from Zaeed, and turned it into an completely immoral merc group who give you endless trouble during the game, and Vido is able to easily invoke We Have Reserves with his recruitment skills. Picking Paragon will let him escape unharmed. Sure, you can pick Renegade and watch Zaeed light the guy on fire, but it means letting Zaeed cross his Moral Event Horizon; like with Balak, you must let many innocent people die to kill your target. Vido is a major reason why Zaeed has become such a psycho. He shot Zaeed in the head. Point is, Vido's caused a lot of damage in many more ways than one...
The 3rd game resolves some (but not all) of these: Rana Thanoptis wasn't just working for Saren, she was indoctrinated. If you didn't shoot her in the first game, she kills a bunch of asari military officers before committing suicide in custody. Balak shows up again, and you can either kill him or ask for his help; it's your decision whether justice is worth more than the help of the Batarian fleet he will bring. And Gavin Archer shows up, sincerely remorseful over his actions and helping the Alliance against Cerberus, who have a standing order to shoot him on sight. Whether or not that's enough is up to you. Even Vido gets his according to some dialogue that doesn't appear in the final cut. Zaeed caught up with him again and let him get harvested by the Reapers.
In Max Payne 3, you never get a chance to cap Anthony DeMarco Sr. for all the grief he's put Max through. On the other hand, you did just kill his son and most of his army. Max just lets Serrano go back to being a killer just half a day after watching him murder Mrs. Branco. In front of her sister. Whether or not this is justified (Serrano may or may not have had his guts surgically removed and his friends and family turned into organ pulp) is unknown.
Dynamo from Mega Man X5 was the one that wiped out everybody on the space colony Eurasia, before sending it plummeting towards Earth in Sigma's scheme. Regardless of your actions, it still wipes out most life on Earth and has repercussions up to the Mega Man Zero series. He also personally challenges and attacks X and Zero in both this game and in the sequel when they bump into him, and escapes every time he's defeated ending up no worse for wear. And to top it off, our heroes only know him as a Smug Snake that keeps pestering them, oblivious to his true crimes. After these two games, Dynamo just disappears from the series, and there's no official resolution to his fate in any manner whatsoever, making him one of the most destructive villains in the franchise and arguably the only one to escape any real punishment.
Mr. Match (Hinoken) from Mega Man Battle Network joined the terrorist organization World Three twice. In the third game, he even tricks Lan into bombing the government's main HQ, something Lan angsts about. Yet he's still free in later games, and Fireman even shares his soul with Megaman as a powerup, appearing in every game (except 5 for some reason) including spin-offs. Among other examples, Pride nearly killed several foreign representatives; Dark/Dusk committed what amounted to an act of genocide. And yet nobody bats an eye when they show up as allies in the fifth game.
Metal Gear Acid 2 has a Karma Houdini in the form of General Wiseman. Even though he was arrested in the story, his reaction in the ending heavily implies that he intends to get out of jail sooner or later in some way, shape, or form.
Villains in the Nancy Drew games often pull a Karma Houdini, particularly when their attacks against Nancy herself are concerned. In Last Train to Blue Moon Canyon, the villain deliberately causes a cave-in to trap Nancy and leaves her to die, yet the only punishment mentioned is that the culprit's credit cards are taken away. Likewise, villains who'd tried to drown, strangle, and/or burn Nancy alive wind up going to jail for robbery.
The Player himself in Overlord. It's stated by Word of God that every Overlord winds up in the abyss eventually. The first Overlord goes there willingly and takes over. It seems a bit far-fetched that the ruler of the underworld would have to play by its rules and be a victim. This also retroactively affects his son, the protagonist of the second game, as the first one was, canonically, an Anti-Hero at best, and probably wouldn't allow his kin to suffer. And from the first game, your jester, who is the quickest to jump ship when your predecessor shows up to take control back and later attempts to summon the fallen God, fleeing first and giving a taunting gesture when the portal closes just after he gets out through it. He's not present in the second game, however, so he may have been given comeuppance at some point offscreen.
Beldam, a Dragon with an Agenda who willingly executed an Eldritch Abomination's plan to be released by manipulating the Big Bad, Grodus, and the heroes into opening the titular door. She also told Grodus that after he released the Shadow Queen, she was bound to obey the one who freed her. The second he tries this, said Queen lets him know this was a lie, and blows him to bits. After the Queen is defeated? Beldam apologizes for abusing her sister Vivian and promises to never do it again. This is the last we hear of her.
Lord Crump is last seen living in Poshley Heights with Grodus (who isn't so lucky, he survives, but only his head remains) and four X-Nauts, having resolved to turn over a new leaf. He hasn't been seen since, so it can be assumed he retired. Doopliss actually benefitted in the end; when Flurry decides to go back to show business, he becomes her partner, acting as Mario in a stage production of the adventure.
Invoked in Persona 2: Innocent Sin. Jun became Joker due to his anger over the perceived notion that Tatsuya and co never received punishment for almost killing his close friend Maya years ago.
But at the same time, Nyarlathotep gets away with it and forces the heroes to give up their friendship. But by the end of its other part, Eternal Punishment, he gets what's coming to him, even though Tatsuya and Katsuya don't get to be with Maya.
This is discussed regarding Namatame. The first aversion comes in the fact that soon after, you get the option to kill Namatame, though it's not recommended as the second comes with the revelation that he was an Unwitting Pawn the entire time who genuinely believed he was helping everyone.
A less serious example, Chie and the rest of the girls get away with punishing the guys for entering the baths during the trip to the Amagi Inn, even though it was really time for the guys to use it.
Another less serious example, Chie buys rather expensive clothes for Teddie's human form with Yosuke's money. She's certainly called out on this because she used his money without his permission and he was actually saving up for a motorcycle, but she ultimately gets away scott-free and doesn't even bother apologizing, not even seeing the problem with this.
Averting this is the primary goal of the Persona 5 protagonists, who are fed up with adults abusing their power to get away with whatever they want.
Despite being caught by the agency, the model from Ann's confidant chain who was sabotaging other girls gets to keep her job and is shown to be the same Bitch in Sheep's Clothing as she was before.
Haru's fiance never gets any real comeuppance for being a jerk who treated her like an object beyond missing out on the chance to get his hands on her fortune after she has their marriage cancelled.
It's implied near the end of the game that some NPCs still intent on exploiting the Metaverse after their boss's defeat don't face any kind of comeuppance, including the Interim SIU Director, who puts Sae on administrative leave when she refuses to back down from prosecuting their boss.
A heroic (?) one: Before he joins the Phantom Thieves, Yusuke threatens to report the crew to the police for harassment, and later blackmails Ann into posing nude for him in exchange for not doing exactly this. Once he awakens to his Persona, these two threats are never brought up again outside of being Played for Laughs as a Running Gag.
The whole villagers of Phantom Brave essentially treated Marona as a slave where despite promising her bounty, after the mission is over and have their lives saved they immediately turned back against their contract and kick her out of their vicinity. By the time they were Easily Forgiven, they do not have a single ounce of regret, apology or hell anything to make up for Marona at the way they treated her, they only treated her nicely because of the entrance of Sulphur.
Most villains in the Pokémon games. Their actions range from running a nationwide criminal empire (Team Rocket), to unleashing and attempting to control a rampaging god with the power to either create continents or expand the oceans (Team Aqua and Magma), to attempting to hijack either the avatar of time or space to destroy the universe and remake it in typical A God Am I fashion (Team Galactic). None of them, willing or not, suffer any repercussions.
Lusamine from Pokémon Ultra Sun and Ultra Moonused Cosmog to open an Ultra Wormhole, released the Ultra Beasts that killed or injured many innocent people and Pokemon, as they wrecked every piece of civilized land in their path and nearly destroyed the rest of Alola. If you lose to her in a battle, she escapes to Ultra Space, still causing no end of trouble for everyone around her with seemingly no punishment whatsoever.
Silver in Pokémon Gold and Silver, who steals his starter Pokemon and another Trainer's Sneasel is never dealt with by authorities or anyone else in regards to the stolen Pokemon for the rest of the game, aside from Elm forgiving him after seeing how much his starter likes him.
In Pokémon Colosseum, Evice and Nascour lose any claims to Karma Houdini privileges when Ho-oh shoots down their escape chopper, leaving them to go with Sherles and Johnson on the Party Van. The four Cipher Admins seem to get away scott free, however; they later appear as opponents in the Deep Under, and what ultimately happens to them is unknown. (Except Miror B., who appears in the sequel.)
Ardos from Pokémon XD: Gale of Darkness, on the other hand, is the big one. His father, Greevil, chose to side with Eldes, the other son, and accept arrest instead of blowing up Citadark Isle with you on it. Even after this, Ardos appears as an opponent in the Orre Colosseum and makes clear his intent to rebuild Cipher; both by giving Michael a warning that he will be watched and branding him as "Cipher's Biggest Enemy". This is the guy who could have gotten away, killed you and the rest of his group from the safety of his chopper, and reconstructed Cipher for absolute dominion in the following months, and has likely backed up all the vital data on Cipher's Shadow Pokemon research. It's very likely he was intended to be the Big Bad of a sequel that never came to be.
In Pokémon Mystery Dungeon 2, Team Skull (as always, consisting entirely of poison Pokemon) constantly provides conflict, going out of their way to hurt or discredit the main characters while scheming to steal various valuables for themselves. In a later dungeon, they mug the heroes and run off with an item that is necessary to resolve a particularly significant crisis, only to be ambushed by an unrelated group later in the dungeon. Once the main characters show up, the Skuntank leader pretends to accidentally drop the item, allowing the heroes to reclaim it. After the heroes leave, a conversation raises the possibility that this one act may have redeemed everything evil they had done up to that point. Are there any players out there that buy this?
Darkrai. After manipulating legendary Pokemon, causing the planet's paralysis (until it was stopped), putting Azurill in an endless nightmare, and almost making the main characters commit suicide, all that happens is he loses his memories and gets to more or less start a new life.
In the terrorist campaign for Police Quest: SWAT 2, you play as Dante, The Dragon of the Five Eyes terrorist group. After a dozen missions filled with murder and kidnapping, the final mission sees you betrayed by your boss, and Dante escaping from SWAT on a private jet. Mocking the Big Bad's obsession with haiku, Dante composes a poem of his own: "The criminal life / Isn't cool / I'll live my life / By the golden rule", and sets course to the nearest tropical island paradise.
Bill Hawks in Professor Layton and the Unwound Future was responsible for an explosion 10 years ago from a failed time travel experiment that he ran prematurely for his corporate sponsors. In spite of the failure, he receives a fortune and goes on to become Prime Minister. At the end of the game, although he gets kidnapped by Clive and Dmitri, Layton still saves him anyway, and he clearly regrets nothing that he's done.
The chief antagonist of Psychonauts, Coach Oleander, gets off with naught but having to say to the campers "Sorry I had you all kidnapped and your brains removed to power my weapons of mass destruction." He even gets all his psychological daddy issues magically resolved by Raz. His accomplice, on the other hand, falls out of a high tower to a probably very messy death.
Captain Qwark in Ratchet & Clank manages to do a pretty good job. Thanks to his status as Comic Relief, he manages to survive being both The Dragon and the Big Bad in the first and second games, respectively, doing galactic scale, off-screen damage. It's implied that millions were killed or kicked out of their homes. His punishment is mainly embarrassment, such as becoming a monkey temporarily, but he manages to become a hero again in the third game. He is even responsible for accidentally handing the fifth game badguy the MacGuffin, and he is now 100% in the clear.
Karma seems to have low accuracy with him. In Ratchet and Clank Future: A Crack in Time he does nothing wrong or even particularly cowardly throughout the whole game, and is more competent in helping Ratchet. His ending fate isn't much more pleasant than Going Commando, where he was the main villain.
Angela from Ratchet & Clank 2 counts. Early in the game (while she's wearing a full-body covering suit) she behaves like a true Card-Carrying Villain, to the point that her actions directly result in the death of an innocent civilian, on camera, while she laughs about it. Then she loses her helmet and we discover that she's a girl and of the same species as the main character, and we're immediately expected to believe that she's a hero now. The fact that we earlier watched her laugh with glee as she committed cold blooded murder is never brought up.
Jupis from Rogue Galaxy; he throws a conceited temper tantrum after losing his job, takes the factory he worked at hostage (on a planet that practically sustains itself on said products produced), turns the robots working there into killbots, threatened the lives of anyone who tried to enter said factory, including the beloved Dr. Pocchacio, tried to kill your group when you go in to defuse the situation, attacked you with a giant killer robot, and what happens afterwards??? Nothing. He escapes, sneaks onto your ship, and gains the love of the overweight captain and crew due to his cooking skills and kinda forces his way into your group.
Killbane in Saints Row: The Third, depending on the player's choices. If you decide to save your friends instead of chasing after him in the penultimate mission, he escapes the city. No big confrontation, no chance to track him down, he just gets away. And if you decided not to unmask him in the previous mission (in exchange for learning the secret of his Apoca-fist), he's even spared public humiliation before he goes. The ending where Killbane escapes is canon, but he seems to have lost his Karma Houdini status sometime before the events of Saints Row 4 when Shaundi confirms his death in a conversation with Roddy Piper.
Laura, an NPC in the firsttwo games achieves this status by Saints Row: Gat Out of Hell, as she died and went to heaven whereas her husband, Tobias, went to hell, despite the two of them being noted drug dealers. Perhaps it's because Laura went to jail between the first two games and Toby didn't, but even then, she didn't even finish her sentence before the Saints busted her out.
Sengoku Basara: Samurai Heroes does this. In his blue path, Motonari Mori plots to take over Japan by manipulating Mitsunari and Motochika to accomplish this task. When Motochika kills Ieyasu, Motonari then carries out his plan to kill off Motochika as well as Mitsunari and Yoshitsugu. When it comes time for the three to make Motonari pay for his deceiving ways, they are the ones who get killed off instead, leaving Motonari to rule Japan.
Unless you believe the Black Arms Invasion or the destruction of Prison Island, GUN from Sonic the Hedgehog never receives any form of punishment for massacring hundreds of innocent people, including a child, in cold blood, just to cover up a failed experiment they funded.
Abbot Hugo in Shin Megami Tensei IV is practically unique among Shin Megami Tensei villains in that he goes completely unpunished on every route. He's a corrupt monk and one of your character's commanding officers in the early parts of the game who frequently bends the laws of the kingdom to make himself richer and more powerful, acts like a complete Jerkass to everyone he meets including the noble Commander Hope, and is even implied to have framed several of his enemies for capital crimes to get them out of the way. Even on the Chaos Path, which typically entails Holier Than Thou Law-aligned characters like him meeting grisly ends, he lives, on on Neutral, which is the most likely path to be canon he's actually welcomed into the good guys with very little fanfare. This may be acceptable as he's by far the least dangerous antagonist in the game; even the Big Bad Wannabe, Mister Tayama, is a greater threat.
George Sewell in Silent Hill: Downpour. He's the cause of the entire events behind the game, and directly responsible for Frank Coleridge's death (Whether he did it himself or convinced Murphy to do it is up to the player's actions). He's also responsible for all manner of illegal and corrupt activities with the prisoners, but in the end he only gets his comeuppance in one ending, which isn't even the best ending to get. In the end, as far as anyone except Anne and Murphy knows, Murphy killed Frank for no reason and Sewell is completely innocent, and in three of the four endings, he walks away scot-free. Subverted in the canon ending, where Anne kills him.
In the original timeline, while Andross's plans were thwarted in both 1 and 2, what Star Fox actually destroyed in both games were merely remote-controlled computers and not Andross himself. Thus, he got no actual comeuppance.
Despite their Wolfen ships being shot down in horrible fiery explosions numerous times by the Star Fox team, Star Wolf will always inexplicably return unscathed, sometimes in the very next cutscene. The only time they ever appear to be even slightly worse for the wear is in Star Fox 64, if Venom is approached from Area 6, where they suddenly appear to have cybernetic enhancements in their communication icons — though this only makes sense from the player's perspective if the Fichina base was previously saved from a bomb by defeating the four of them in time, which doesn't necessarily happen in a playthrough.
Taken to a meta-level: Lord Scourge in Star Wars: The Old Republic.Pureblood Sith that answers only to the Omnicidal Maniac Emperor. He literally stabbed the Jedi ExileIn the Back, got T3-M4 turned to ashes, and betrayed Revan and got him sent to Malestrom Prison for 300 years of torture as the Emperor's pet chew toy (driving him genocidally insane in the process). But Even Evil Has Standards, and Scourge doesn't want the Emperor devouring the whole galaxy because that's where he keeps all his stuff. So, he merrily invites himself on the Jedi Knight's boat, sourly disapproving of everything the Light sided Knight does, and helps the Knight kill his boss. Does he repent? Does he face any fallout for what he did to the protagonists of the last two games? Heck, no! Does he merrily get away with it? Heck, yeah! The Knight apparently doesn't even mind that Scourge keeps trying to recruit them to the Dark Side. And just to put the cherry on the Karma Houdini sundae? He saunters up to Revan and Bastila's decendant to accept a Republic heroism reward! (Satele is pretty disgusted at having to give it to the louse.) Interestingly, he does express regret when the Hero of Tython talks about it; he admits he liked them but felt that stopping the Emperor was more important.
Rowd from Suikoden II. It is true that he is a Glory Hound that seeks a better life for his ill sister. However, with his methods to achieve it, including helping Luca Blight slaughter the Unicorn Brigade that he led... because the job didn't pay enough, or even trying to kill the hero and Jowy so he can get promoted... we never know how he ends up, as he vanishes from the story after Jowy becomes the King of Highland. Supplemental materials reveal he failed to get his sister to the doctor who might have been able to help her after he ran away, making everything he did meaningless and costing him his sister's life. The fact his innocent sister is the one who dies is another trope entirely.
Suikoden III has Albert Silverberg. He is responsible, directly or indirectly, for every single bad thing that happens in the game. And why is he orchestrating the lead-up to a meaningless war, then partially derailing it, after the lives and societies of thousands of people have been shattered? Just to prove that he can do it. The reward for victory for everyone else is that they get to live another day. Albert? Gets exactly what he wanted, a cushy position miles away from the land he almost destroyed. This man is absolutely infuriating to quite a few players.
Suikoden IV has the elves of Na-Nal. They aren't pleased that the human islanders struck a deal with the Kooluk, so they manipulate matters and spark off a massacre, which the Elven elder gloats about. Ironically, the heroes stopping the massacre before it spreads too far probably caused their karma evasion, as once the Kooluk finished killing off the human natives, they likely would've moved to the elves next...
Super Mario Bros.: The only punishment that Bowser ever seems to get for kidnapping Peach so many times is being humiliated when Mario trounces him. He still rules the Koopas (who remain loyal to him) he's still free to do it again, and neither Mario nor Peach seem to help matters, seeing as the Go-Karting with Bowser Trope happens between them so often he's the Trope Namer. (Of course, it was suggested at the end of Super Mario Sunshine that Bowser is doing it for thrills, and he doesn't want the conflict to end; maybe Mario and Peach are humoring him.)
The series is an idealistic franchise... and therefore, even villains who got away scot-free in their series do not escape the hand of karma. Just to make a point, in episodes with Nadesicothe player is either allowed to kill off Kusakabe (Impact, MX, J), or his plans are screwed up to the point where he is unable to go on and found the Martian Successors (A, R). The same thing happens to Garimos and Gil Barg from Dangaioh (see above), who are actually killed in the Super Robot Wars Compact 2 trilogy and its remake Super Robot Wars Impact. Hard to escape a Karmic Death when you have to deal with a band of Hot-Blooded heroes who have an habit of Punching Out Cthulhu.
Certain major antagonists such as Bian Zoldark and Maier von Branstein are regarded with a certain degree of respect after they are killed. This may be partly because they are related to some of the protagonists.
Several characters seem intent on punishing themselves for things that no one else blames them for. For example, Elzam von Branstien/Rätsel Feinschmecker takes the blame for the "Elpis incident". A group of terrorists, lead by Archibald Grims, took Elzam's wife Cattleya as a hostage to guarantee his escape. When he remotely opened the docking bay door, allowing her to return to the colony interior, he also released a highly potent toxic gas. Elzam was faced with the choice of either destroying the section of the colony that she was on or allowing the gas to poison the colonists. Despite the fact that she was already fatally poisoned, he felt terribly guilty for destroying the docking bay to save the rest of the colony.
Asch. In the beginning of the game, he slaughters around 140 Malkuth soldiers onboard the Tartarus, tries to outright kill the party numerous times (though his main target is Luke, when you first meet him, he makes a comment about how Jade is difficult to kill), and takes control of Luke in order to try and make him attack (and presumably kill) Tear. Yet, just because he's against Van and starts to cooperate (little by little) with the party later on, all is forgiven and nobody mentions the massive amounts of people he willingly, purposefully slaughtered (whereas Anise later reminds Arietta of her participation in the above massacre to drive home that she has also done things that drive people to seek revenge), or the fact he could have stopped everything if he just helped everyone from the beginning. As well as the entire party except Natalia who all lied and deceived Luke yet got nothing equal to what they did to Luke just because they basically said "my bad, sorry".
Anise. Not only has she been spying on the party and reporting back to Van, her betrayal gets Ion killed. Yet because she has a flimsy excuse, she's very Easily Forgiven.
Subverted in Tales of Vesperia had minor villains Ragou and Cumore. Ragou oppressed his subjects and fed the ones that couldn't pay to his pet monsters. Cumore, in the search for Pharaoh, drafted innocent civilians into what amounted as a suicide mission. However, their positions and wealth guaranteed that they wouldn't be touched by the law. It looks like they'll get away with everything until Yuri hunts them down and murders them. It's played straight with Dedecchi, the Aque Blastia thief. This is fixed in the PS3 version, where a new optional event allows the party to capture him.
After Emma spared his life, Umber Gnawbone resolved to start his life anew and give up thieving. ...This resolution lasted for all of 24 hours. Umber remains in command of the Coria Dogs, and was last seen stealing candy from a small child.
Most of the villains in the Time Crisis series get their comeuppance, but in the Special Mode of the original Time Crisis, should Miller fail to defeat Kantaris within the time limit, she'll escape, but not before taunting Miller. She also happens to be a Karma Houdini in the spinoff Project Titan, as she sails away from her boat as it explodes, taunting Miller.
In Tomodachi Life, any angry Mii that rejects the apology of a calmed-down Mii. Sure this calms them down as well, but it sends the apologizing Mii into a Despair Event Horizon where they cannot stop thinking about them (to the point where they continuously daydream about having childish fights with the other Mii, usually over a teddy bear). The apology rejector gets away scot-free, raising no flags for other Miis to talk sense into the rejector. Not even the player can give them a proper scolding that lasts as long and sinks in as much as the Mii that got rejected's sadness.
Eric Sparrow of Tony Hawks Under Ground. He uses the player character as a means to make himself more popular, going so far as to edit a video tape to remove an amazing stunt that the player character had pulled off and leaving the character in Moscow after a drunken ride on a tank causes massive amounts of damage and destruction and he/she tries to stop it. Even though Eric is shown that skating for the sake of skating is way better than skating for money and retrieving the video tape that had your character's stunt still on it, Eric's duplicity is never revealed and he is just left throwing a temper tantrum at the end. Unless you count the alternate ending where the player character decks him in the nose and walks off with the tape.
Kanako Yasaka, the final boss of Mountain of Faith. In Subterranean Animism, she gave the power of a dying god to dim-witted Utsuho Reiuji, causing the latter to go mad with power and wanting to destroy everything. Not only does she not get any comeuppance in Touhou canon, there is literally no fan-material— fanart, fanfics, doujins, whatever— of her suffering the consequences for what she did.
Nadine in Uncharted 4. After spending the entire time trying to kill Nathan & Sam and steal the the treasure before they can, she beats up the two of them in an Unwinnable Boss Fight before leaving them to die in a burning ship with the Big Bad near the end of the game, escaping with some of the treasure.
Eleanor in A New Frontier. When the group plans to rescue David from being lynched by Joan, she snitches on them which leads to Joan killing either Ava or Tripp and Kate accidentally destroying Richmond's walls in an explosion. Her only explanation is that she was "triaging a bad situation" and when Javier confronts her about this she has the nerve to blame him for Richmond being overrun with walkers while asking for his forgiveness. The player can choose to forgive her or not, but there is no opportunity for revenge whatsoever.
This can potentially happen with Joan in A New Frontier. After killing his niece, one of his friends, and attempting to lynch his brother, she and Clint offer Javier's group a chance to leave peacefully. If the player doesn't shoot her in the face the first chance they get, Joan will escape during the walker invasion and it'll be the last time the player sees her.
Can potentially happen with Lilly in The Final Season. If you choose not to make AJ shoot her, she immediately goes back on her surrender and murders James before holding AJ at gunpoint, only to be stopped by the exploding boat. Any attempt to kill her after that fails, and she gets away with murdering Doug/Carley and several of your other friends once again.
Grom Hellscream was the first to drink demon blood and advocate everyone else doing it, he slaughtered countless humans, dwarves, and elves (and others) for fun, and then after getting redeemed, still attacks some humans for no reason and drinks demon blood a second time knowing full well what it is. Sure, he has a Heroic Sacrifice at the end, but he gets idolized by the Horde despite his life being 90% evil, 10% good. In Warlords of Draenor, he's even seen celebrating with the heroes after Gul'dan's defeat, shouting that Draenor was free. Everyone around completely ignores that he started the war to begin with and that he's one of the three most responsible for all the deaths in the expansion (the others being Garrosh and Gul'dan).
Sylvanas. Even before Wrathgate, she kept human prisoners in cages, to be tortured, experimented on, vivisected and lobotomized to be slaves and plague material. Her Royal Apotechary kidnapped innocents to experiment upon under her watch, and keep tortured human slaves for fun and science. She's under suspicion for the wrathgate (we don't know how much she knew, but it is likely she turned a blind eye), invaded Gilneas, nuked Southshore, waged a campaign of genocide, massacre and torture on the Humans, manipulated the Horde (to join them in the first place in order to use them as tools), set herself up as an object of cult worship, employed the Val'kyr (which seems to be a case of "Even Chaos has standards" when seen by pragmatic Death Knight Thassarian), resurrected those who she killed against their will, shot and killed Liam Greymane, attempted to steal the Scythe of Elune to enslave the Worgen and make even more to make an even BIGGER army to do her bidding, and made some kind of deal with the devil to get the Val'kyr in the first place. The closest she got to any kind of punishment was Lor'thermar threatening her if she raised the Horde's dead as Forsaken, stating he'd leave her to the Alliance if she tried it on their dead and calling her out on several of her actions in Mists of Pandaria. In Legion, after retreating from the Broken Shore on Vol'jin's death, she ends up being named the next Warchief of the Horde on Vol'jin's recommendation, despite said retreat costed Varian's life, and rather than fighting the Burning Legion, she ends up plotting to further expand her Val'kyr collection... but Greymane quickly put an end to that, leaving her in very short or no supplies of Val'kyrs... but it still didn't quite deter her yet.
Trade Prince Gallywix. When Kezan is threatened by a volcanic eruption, he tricks the rest of the Bilgewater Cartel into giving him all their money and possessions to buy passage off the island, then enslaves them. On arrival in the Lost Isles, he enslaves them a second time. The player character has to almost kill him before he'll give up, but somehow after the dust settles Thrall decides to keep him in charge of the Cartel. His present whereabouts are unknown, but in Azshara he has a "pleasure palace" on top of a mountain with his face cut into it.
Da Ji from Warriors Orochi. The coalition defeats her in the first game but she gets away with it by teaming up with Kiyomori Taira to resurrect Orochi. In the third game, she teams up with the coalition to destroy Hydra because she considers it as an empty shell to the real one. But she screws up by taking advantage of Orochi's body which turned into Hydra in the first place and to make up for her mistake, she's very serious of taking down Orochi X. In Ultimate, she becomes the Coalition's enemy again by aiding Tamamo and unlike Tamamo who gets sealed in the mirror, Da Ji doesn't receive any comeuppance. In the fourth game, she teams up with Odin to resurrect her master again and only switches sides after the original Orochi is gone. She even gloats that she would still bring Orochi back despite that the man himself wants to be put to rest. Even in the end, she's never punished for her actions and admits she enjoys doing evil things.
Defied in the No Way Out DLC from Wick. The ghosts wait juuuust long enough to let TBubber think he escaped retrubution for desecrating their graves, then ambush him. He escapes them, but not the unidentified third party who clocks him with a shovel...
Wild ARMs 1 opens with Rudy saving the villagers from a group monsters with his ARM weapon only to get immediately forced out afterwards due to using the afromented feared weapon. They are neither punished nor show any remorse for such actions. Thankfully, Alter Code F rectifies this by adding a late game sidequest where Rudy can make peace with Serf Villager after the Rotting Beast comes Back from the Dead.
Both Belda and Lucchini in The Witch and the Hundred Knight gets to continue living their lives scot-free in the "Bad" ending. Belda placed a dog curse on Visco, who in turned killed her to save Metallia instead of lifting the curse. Belda ironically gets revived by Metallia's actions in chapter 12 and does not even recall the events of chapter 11, meaning that unlike many of the other characters who appeared in that chapter and have become better people, she has not changed at all. Lucchini killed his entire village people and even his own father, who aided him in killing lots more people, including Visco in Amataya Kingdom which ultimately cause a great deal of hell for Metallia in her quest to revive Visco in chapter 12 & 13. Though depending on how one may interpret Lucchini, it may be considered Cruel Mercy since Metallia didn't grant his death wish and no longer has any friends or family to turn to.
Ellen from The Witch's House. She befriends a little girl named Viola, earning Viola's trust. Eventually, Viola agrees to trade bodies with Ellen, as Ellen's body is afflicted with a deadly sickness and can barely move from her bed, and Viola was nice enough to agree to take Ellen's pain "for a day". Cue Ellen (in Viola's body) sawing off Viola's legs and gouging out her eyeballs, all in the name of sadism. Ellen also poured a burning liquid down Viola's throat, because she didn't enjoy the sound of her old body screaming in agony. Now, fast forward to the end of the game. Viola almost gets her old body back, but her father shows up at the worst possible time. Armed with a rifle, he fires at Viola, thinking that he's saving his daughter from a monster. While he and Ellen leave the area, Ellen laughs one last time at Viola's corpse.
The Witcher 2: Assassins of Kings: Bernard Loredo can be this depending on the player's choices. If you side with Iorveth, he'll set fire to a tower filled with elven women, forcing Geralt to choose whether to save him or kill Loredo. If you save the elven women, hell not only escape with no punishment for his crimes, he'll actually succeed in selling out Flotsam to Kaedwen.
The Weavess becomes this in either ending where Ciri survives.
Gaunter O'Dimm in the Hearts of Stone expansion. He's an exceptionally powerful and sadistic demon that's been tormenting people for millennia, convincing them to make deals with him that end with him taking their souls. He casually murders a man for offering Geralt a drink when they were trying to talk, and when a scholar tried to learn more about him he blinded the man and trapped him in his own basement for a year before finally killing him. He's very heavily implied to be the series' equivalent of Satan, and the most Geralt can do is temporarily banish him.
The Witch of Lynx Crag of the "A Knight's Tale" sidequest in Blood And Wine. Eons ago a knight came to convince her to lift a drought, and she seduced him in the process. When he went to return to his lover, she killed him and his lover's grief caused her spirit to be trapped in a tree. The witch knew how to lift the curse but never divulged the information out of spite until Geralt gets on one knee and begs her. If Geralt strongarms the witch into helping instead, she causes the woman's ghost to kill the innocent lumberjack who hired him. At no point can she be killed for causing this whole ordeal, and if Geralt gets her to help she uses magic to vanish afterward so he can't come after her.
In the Golden Ending of Blood and Wine, Syanna, who orchestrated all the horror and tragedy of the main quest for a ridiculously petty reason, is implied to get off scot free for her crimes since her newly reconciled sister the Duchess refuses to punish her harshly like she would any other criminal. And to make matters worse, any attempt by the player to have Syanna face justice for her crimes results in a Downer Ending.
Tweedle Dee, Tweedle Dum (if you don't kill him), Ichabod Crane and Jersey Devil all survive without imprisonment or death in The Wolf Among Us (though Crane is letter killed by Bigby in the comic book series).
In Xenogears, the main antagonist, Krelian, is never fought or killed. He had been responsible for many heinous crimes but was never brought to justice.
Albedo from Xenosaga certainly applies. Throughout the trilogy, he manages to Mind Rape MOMO twice, abuse and mercilessly torture and kill the Kirschwassers, kill many with Proto Merkabah, torture Jr. by giving him various visions of the past involving Jr.'s dead love interest Sakura, and manipulate many in his selfish desire for his goals. What is this goal? To make Jr. hate him so he can be killed. And he actually does succeed. Jr. gets pissed and offs him. Then Jr. CRIES after the guy who decimated so many lives is finally killed off. But that's not the end of it. Albedo is then revived by Wilheim as a testament, and gains uber powers. He just toys around with the party until near the end, when he, for the first time ever, actually manages to try to do something helpful for the party when he tries to stop Yuriev from merging with the Zohar and becoming all invincible and such. However, Gaignun, the third dude in their power trio, who had spent all of episode III possessed by Yuriev, intercepts and allows Albedo to merge with Jr.'s consciousness as it was originally when they were born. This is all Albedo ever wanted, and he goes to sleep blissfully inside Jr. The most enraging part about all this is that whenever Albedo manages to top himself in evil, Jr. gets pissed at him for about 5 minutes before Albedo gets defeated by the party, and then Jr. instantly turns into a whimpering dog that begs Albedo not to leave him. Even MOMO sympathizes with him, even after he had his way with her.
Even though the Ace Attorney protagonist's job is to find the guilty and absolve the innocent, a few people slip through the cracks.
In the second Phoenix Wright: Ace Attorney game, De Killer is an assassin for hire who kills the fourth case's victim in addition to (presumably) many others in the past. He kidnaps and threatens to kill Maya if you don't acquit his client, and then gives testimony in court via radio to try to pin the crime on someone innocent. The way the story is structured, he kinda has to remain free in order to give the testimony by radio and to be able to threaten Engarde when it is revealed Engarde videotaped him to blackmail him. He reappears in Investigations 2... and he gets away there too, despite Edgeworth's best efforts.
In the 3rd game, Ron DeLite, a.k.a. Mask☆DeMasque the Gentleman Thief. While he didn't commit the murder, he didcommit four incidences of grand theft. When he was framed for a fifth, he was put on trial - and found Not Guilty with the help of Phoenix Wright - for all of them. And due to double jeopardy (you can't be put on trial for the same crime twice), this means that he remains unpunished even after his crimes are publicly exposed. In the epilogue, he explains that he quit stealing and became a security consultant along with his wife Desiree - along with a side business of selling plans to criminals. He comments, rather accurately, that "Sometimes I think maybe we're the worst criminals...". Still, the whole reason that case even happened is that Ron got caught by Luke Atmey on his very first crime, indicating his crime-planning abilities completely suck. So by selling his crimes to other criminals, he may actually be lowering the crime rate... Also, one might consider the terror of getting caught, arrested, and nearly convicted of murder to be fit punishment for a relatively minor crime.
This theme is completely reversed in Investigations. The Yatagarasuor rather Detective Badd, the last remaining part of the Yatagarasu, turns himself in to Gumshoe after the arrest of Shih-na/Yew and the revelation that they and Faraday were the Yatagarasu team. He even seems as if he meant to be arrested the entire time and was only waiting for the capture of Yew before "retiring".
When Mob Boss Bruto Cadaverini found out his Mafia Princess granddaughter, Viola Cadaverini, was injured in a car accident, he forced the other driver, small time criminal Furio Tigre, to pay for Viola's million dollar operation, or else. This actions causes Tigre and Viola Cadaverini(who had become infatuated with Tigre) to murder a man and frame an innocent woman for murder to pay off the debt, thus making Bruno responsible for the entire case. Despite this, Bruno remains at large at the story ends with no punishment, the police admitting they can't touch him. To a lesser extent, Viola is let off pretty easily for being part of Tigre's frame up plan.
And then there's Phineas Filch in Phoenix Wright: Ace Attorney Dual Destinies, who is a habitual pickpocket (and stole the properties of several of the main characters), willfully committed perjury and even conspired with the villain to provide an alibi, but is never indicted or punished at the end of the game. On the other hand, he never did get the gold nugget he craved and was subjected to plenty of verbal and physical abuse from Simon and Taka, respectively.
Simon Keyes, the Big Bad of the second Investigations game, manages to be a Karma Houdini even when he gets caught! It's clear that he will be able to beat the murder charge (that particular victim was earnestly trying to kill him at the time), and while he will do some time for a few of his other actions, it's in the same prison as his mentor, which hardly counts as punishment. He even gets sympathy, both in and out of universe: the fact that his aim was to bring several much worse criminals to justice probably helped. Karma only singed his suit.
A number of the prosecutors get off easily despite doing things that should earn them at least a professional reprimand and at worst assault charges. Yes, they change in the end, but Franziska publicly whipped Phoenix unconscious when he first defeated her and has used the whip on at least two judges, and Godot threw cups of hot coffee at Phoenix's head. Not to mention the former's ethical violations.
In one of the paths on the visual novel Crescendo ~Eien Dato Omotte Ita Ano Koro~, the heroine of that path will be gang-raped, and no matter what the player does, the rapists fail to get any comeuppance at all. The heroine even makes him promise not to report the incident to the police. One can only assume that the rapists continued into the sunset twirling their mustaches and giving each other high fives. Worse, they're never even named, and we've seen Ryo fight off three nameless guys before (breaking one's arm in the process). The best we can assume is a bit of impromptu off-screen justice for the guy who's appeared more than once. And the heroine's cousin raped her nightly; the aunt and uncle weren't exactly believing of the truth.
Danganronpa: Genocide Jack is a Serial Killer who has taken the lives of many "cute boys". However, despite that, she goes on to survive the events of the first game as she does not kill anybody nor does she ever get killed (though Pragmatic Villainy ends up having a case for the former).
In the Fate and Unlimited Blade Works routes of Fate/stay night, the protagonist never even finds out about Zouken Matou, and he is presumably still torturing Sakura, which is one of the primary reasons fans consider those routes to have Bittersweet Endings.
Shinji gets away scot free in Kara no Shoujo in several endings. He even casually hands off Toko's body to a kid on the train before just disappearing from the story. However, he is revealed as a pretty tragic figure around that time, so some readers may feel he doesn't deserve to be punished so long as he stops.
Shichiou and April in Princess Waltz. The first gets a sort of half assed 'forever in death with my beloved, who is not holding a grudge' ending. The second might be a god and just sort of skips merrily away at the end after reviving Pigeon. Then again, she didn't really do anything particularly bad either.
Starless: Nymphomaniac's Paradise: None of the members from the Aristocrats Are Evil family ever get their comeuppance in any of the endings, even the Golden Ending, to put it simply.
At the end of Nine Hours, Nine Persons, Nine Doors, Zero and The Dragon (Akane and Santa) merrily fuck off into the sunset without receiving any comeuppance for trapping 9 people in a death game. Advanced psychic powers are a bitch, aren't they?
At the end of Virtue's Last Reward, the masterminds behind the Ambidex Game (Akane and old Sigma) merrily fuck off into the sunset without receiving any comeuppance for trapping 9 people in a death game.
Mira, who is the heart ripper serial killer. Outside of the scene where it's revealed as such to the player, the fact that she's a serial killer is never brought up, and she's there at the end of the game along with everyone else for the finale, even agreeing to help with changing the future. To be fair somewhat, the game's written epilogues do show that she turned herself in after the game, and Sean even brings this entire issue of her guilt never going away up to her. But that doesn't really change the fact that, all things considered, she had a fairly decent ending for herself. Even to the point of marrying the son of her first victim while in jail, and actually getting broken out of jail by Sean so that she can go and save an alternative history version of herself from making the same mistakes she did. It's never shown if she even turns herself back in after doing this or not.
