Mainstream criminals have a morality scale of their own (though in some cases, said morality may involve them being worse). Many of them despise police officers and prison guards (including cops/guards sentenced to prison), snitches, sexual offenders (especially child rapists), and sexual minorities or members of certain racial/ethnic groups. Truth in Television featured in many works of fiction.
If prisoners of these groups get locked up together with mainstream criminals, they might be beaten up in a Prison Riot, become the victim of Prison Rape (a kind of Karmic Rape for sexual offenders), or even murdered, typically with a Sinister Shiv.
See also Asshole Victim as a possible outcome, Moral Event Horizon for atrocities that may make them unwanted, Blue-and-Orange Morality for the peculiar rules that dictate what is acceptable and whatnot, and Even Evil Has Standards for one possible reason that some prisoners become this.
- The Punisher:
- Frank once visited a not-quite Luxury Prison Suite where it was mentioned that the occupants (who can have just about anything smuggled into their cell except women) made use of cross-dressers with toothless mouths who knew how to use them, considered the lowest of the low.
- Frank himself is generally put into solitary after a while, as the first thing he does when he's in prison is kill a few inmates, whether they come after him for vengeance or street cred.

- Serial killer Cletus Kasady usually gets a cell of his own due to possessing a carnivorous alien parasite and being more than happy to use it to kill anyone and everyone in his vicinity. When separated from it in Superior Carnage Annual, he was re-introduced into the general populace in an attempt to rehabilitate him. The other prisoners treated him with contempt and one of them — who had been hired by his therapist — shanked him. After the symbiote returned, Cletus returned the favor.
- In Top 10, Atoman - publicly a veteran hero, but actually a pedophile and ringleader of a child porn business - chooses to commit suicide rather than surrender to the police, as he believes he'll be permanently de-powered before thrown into prison, making him an easy target for his many past enemies there. Just as the police hoped, since they wanted to avoid Atoman breaking out and wreaking havoc with his powers.
- In Hard Time, Lewis Gatherwood is in State for the rape and murder of a young (implicitly very young) black girl.

He was dead only a few days into his sentence.
- Sinister Dexter has Sinister go into prison to find Dexter. Finny soon discovers that gun sharks like him are at the bottom of the food chain, mostly because of the hits carried out on mobsters whose friends are in prison.

- At the end of Crumbling Down, after being sent to juvie, Lila attempts to start up her old tricks. However, due to her fellow inmates both being aware of her status as a chronic liar as well as having no restraint in physically attacking her, Lila quickly ends up in the infirmary several times before being sent to solitary confinement for her own safety after one too many tries to assert herself ends with almost the whole prison trying to kill her.

- The members of God's Will First, upon their arrest, are noted by the narration to have barely spent any time in the main prison population before getting sent to the Vulnerable Prisoners Unit or the infirmary, implying they weren't all that popular with the other prisoners.
- Part of the motive rant of the villain in The Bone Collector is that he was a former cop who was thrown in prison.
"Do you know what happens to a cop in prison? You are brutalised every single day over and over... you become a human toilet."
- Gamora of Guardians of the Galaxy (2014) is this on The Kyln due to her being affiliated with and working for Thanos, which made her a lot of enemies. Indeed the first night there a group of prisoners plus Drax try to kill her and she survives only thanks to Peter.
- The Hunter (1980) (Steve McQueen's last movie before his death that year) had LAPD character "Detective Spota" facing this unenviable fate because he stole and sold drugs from an evidence locker but instead commits suicide to avoid facing this.
- An Innocent Man (1989, Tom Selleck) has David Rasche's ex cop character facing this when he is sent to the same prison after being convicted of drug dealing.

- Better Call Saul:
- Mike says that cops fear prison more than death.
- Inverted by Saul himself. When he's finally arrested for his part in Heisenberg's crime syndicate at the end of the series, he ends up sentenced to over 80 years in what would normally be a Hellhole Prison filled with some of the worst scum imaginable. However, it ends up not being that bad for him, since all of the prisoners there practically worship him. After all, he spent his entire career as an Amoral Attorney keeping guys like them out of prison. The worst thing he can say about it is that he's working in the kitchen there, essentially doing the exact same thing he did in his boring life as Gene the Cinnabon Manager.
- At the end of the Law & Order: Criminal Intent episode "Stress Position", Goren manages to shame each of the corrupt prison guards who killed the Victim of the Week (and are trying to make another witness suffer an "accident") into turning themselves in.

The Homeboys, however, were pissed off when Coyle ended up dead, albeit for "political" reasons rather than moral ones.
- Mershah becomes this when he gives up information to the guards to get revenge on Saïd, triggering a search that leads to Em City's entire population being punished for hiding various weapons and drugs. He's eventually Driven to Suicide by the isolation.
- Prison Break:
- When Brad Bellick is framed for murder and sentenced to 20 years imprisonment, he has the bright idea to request a sentence at the same prison where he used to be the captain of the guard, thinking that his old status will grant him protection by his former colleagues. It backfires because the new hardline Warden is adamant about no privileges being accorded to anyone, so he quickly becomes a target for reprisals.
- The Sona prison in Panama has a specific prisoner who is designated as the pariah and is completely ignored by the other prisoners, not even giving them any food (they feed on leftovers). This happens to Brad Bellick (the guy can't catch a break it seems) when he refuses to give up his belongings on his arrival, and only gets accepted after winning a fight much later.

- In The Laramie Project, one of the characters mentions that Aaron McKinney and Brian Henderson, the murderers of Matthew Shepard, were not very well-received by their fellow inmates.
- The 1974 play Short Eyes by Miguel Piñero (Obie Award, Drama Desk Award, Tony Nomination, made into a film) is about an accused child molester in prison. Nearly all the other inmates turn on him for his crime. The term "Short Eyes" is prison slang for a pedophile.
- Invoked in Mirror's Edge: one of the reasons Faith is so adamant about clearing her cop sister Kate's name before she stands trial is that "blues in jail don't last long", as she tells Captain Miller.
- Prison Architect. A constant concern. Snitches and ex-cops need to get into a segregated unit.
- This is the fate of Superintendent Pendrew in Sleeping Dogs (2012). Wei is given evidence that confirms him as the killer of Uncle Po, meaning that he's not just going away as an ex-cop, but also the man who killed one of the underworld's most-respected figures.
Pendrew: That's a fucking death sentence!Wei: That's the plan.
- The Magician: After one pirate-themed Villain of the Week was defeated and arrested for taking artifacts from a museum and trying to drown the protagonists, he was told by another inmate, "In this jail, we don't like people who steal from museums!" causing him to scream in fright!
- Double Subverted in the episode "Peternormal Activity" of Family Guy. After Peter and the guys accidently killed an old war veteran, Joe talks Quagmire out of reporting it, telling him that they are going to prison for this and "you know what they do to cops in prison". It cuts to a Imagine Spot where a prison inmate asks a bored Joe several questions about the police like an excited, curious child ("when you were a cop, do they let you use the siren?") and then, right afterwards, this same inmate casually says that he and several others prisoners are going to kill Joe in the shower later.
- The authors of the Hi-Fi murders were despised by their death row cellmates, to the point that Gary Gilmore, en route to the firing squad, exclaimed he would see them in Hell.
Gilmore: (paraphrased) Adios, Pierre and Andrews. I'll be seeing you directly.
- Pedophile Priest John Geoghan was murdered by Joseph Druce, who was serving a life sentence for murder (and now serving a second life sentence for Geoghan's death). It was suggested at the time that Druce killed Geoghan to gain prestige in the prison hierarchy.
- Serial Killer Jeffrey Dahmer was beaten to death by Christopher Scarver in 1994 while serving barely three years into his multiple life sentence. He was declared mentally competent to answer for his crimes, thus placed in the general population. What is notable about this incident is that Dahmer was white while Scarver is black. Normally, undesirable inmates such as pedophiles are always "handled" by inmates of their own race. To cross racial barriers on such an issue is a violation of prison politics, regardless of the end justifying the means. However, Dahmer was considered an acceptable exception due to the fact that while he was a white man, the majority of his victims were black males.
- James Eagan Holmes, the gunman who gained infamy for The Dark Knight Rises shootings in Aurora, Colorado, became this as not only that the judge expressed absolutely zero sympathy towards the shooter for maiming if not slaughtering scores of people including children who were at the theatre for the premiere, declaring that Holmes may "never set foot in free society again" and giving Holmes a Longer-Than-Life Sentence,note a fellow inmate named Mark "Slim" Daniels attempted to murder him ostensibly to avenge the deaths of Holmes's victims. Whether Slim's motivation for sending the Dark Knight spree shooter to hell is sincere or not is debatable though, as he might have done this merely for the notoriety.
