Poison Is Evil

In many, many works, when poison comes into play, it is the villain who primarily uses it, and indeed, use of poison by a character is seen as very suspect at best, and a strong sign that the character is evil at worst. Very few heroes (apart from antiheroic Combat Pragmatists) will use poison, considering it dishonest and dishonorable, and if they do use it, it's likely to be something aimed to knock people out such as tranquilizer darts rather than something deadly like arsenic or cyanide, which ties into Thou Shalt Not Kill.

It's not hard to see why poison is considered evil by many. The notion of normally life-giving food or water becoming something that can hurt or kill people, for example, terrifies us, and the use of it is quite sensibly banned in many cultures. Many rulers have fallen to poison, and just as many take precautions against it, such as food tasters. We often use the word "poison" figuratively to describe something destructive or corruptive, such as "poisoning someone's mind" or "poisoning the well" in a debate. Latin ("veneficus"), Hebrew ("kashaph", "qesem") and Navajo ("’ánt’įįhnii") all derive their words for witch(craft) from roots that have to do with poison or poisoners.

The use of poison in combat, such as Poisoned Weapons, is widely seen as cheating and dirty fighting, primarily employed by cowardly villains or villainous Combat Pragmatists who care nothing about honor, only about results -- usually the poison-using villain's aim is to either murder someone, gain an unfair advantage, or render someone helpless who would otherwise have wiped the floor with them in a stand-up fight. Depending on the effects of the poison in question, things can get awfully dissonant when other non-poisonous abilities exist (blinding flashes or holy power that weakens The Undead, for example) that do pretty much the same thing as what the poison does and are used quite freely by heroes to bring down their opposition. Because of this, poison's limitation to villains can sometimes take on the status of Designated Evil.

Historically, this trope is most traditional in Western Europe and its descendants -- others rarely cared unless there was a breach of Sacred Hospitality or fair duel. In tropical regions hunting with poisons was widespread; in Hindu tradition poisonous critters are just another fact of life, and cobras even revered sometimes. China didn't see poisons as something special, nor did Steppe peoples, Russians shrugged. Americans risk to run into The Savage Indian with it, but the choice of setting usually averts this.

By the same token, this trope is ubiquitous in Medieval European Fantasy, but never applied in Hungry Jungle settings, for minimum of realism and Darker and Edgier tone.

Note: This is not just a villain who uses poison; This is where the use of poison is seen as a villainous trait.

Anime and Manga

 * In Noir, Shaoli delivers deadly poison with a mere scratch of her fingernails. She's treated as objectively villainous,
 * At the beginning of Pokémon, Jessie and James of Team Rocket both used Poison-type Pokemon, Ekans and Koffing, until the beginning of the Hoenn region.
 * Played straight in Naruto. One would think that use of poison would be common among the ninja heroes, but so far it's mostly been only the villains (Sasori Kabuto and Hanzo) who use poison,though Kankuro and Shizune use them rather liberally with Shizune helping Sakura get in on the act.
 * Played with in One Piece via Magellan, the warden of the prison Impel Down. His Devil Fruit, the Venom-Venom Fruit, allows him to generate poison from his body at will. While definitely an antagonist, as the Impel Down arc has Luffy breaking into the prison to rescue his brother, Magellan is also the last line of defense keeping many of the worst criminals in the One Piece world from seeing the light of day.
 * There are also plenty of villain who aren't afraid of using poisoned weapons, including Don Krieg, Crocodile, Wanze and Duval.
 * The few times that poison has been used in Berserk, it has been the province of villains, such as Adon Corbowitz's use of poison in his duel with Casca, or the conspiracy to kill Griffith.
 * In Fairy Tail, one of the many "second generation" Dragon Slayers that Natsu encounters is Cobra, the Poison Dragon Slayer. He is, unsurprisingly, evil.

Film

 * Inverted in The Princess Bride.
 * Played with in 9 to 5, when Violet fantasizes about killing Mr. Hart. She imagines herself as a Snow White-style Friend to All Living Things, yet bumps him off by poisoning his coffee, to the general rejoicing of animated Woodland Creatures and desk-chained employees. An animated vaporous skull-and-crossbones appears above the coffee cup when she pours in the toxin.
 * Though Kill Bill has assassins as major characters, Elle Driver, the most evil and treacherous of the Deadly Viper Assassination Squad, is the only one in the saga to make extensive use of poison. She tries to poison the Bride while she's in her four-year coma, only to be warned off by Bill, who considers the act to "lower" them, and later uses poison in her killing of.

Literature

 * In A Song of Ice and Fire, poison is commonly seen as the weapon of a coward or a woman. Or, when it's convenient to blame one for a poisoning,.
 * Mentioned in Interesting Times: Cohen the Barbarian and his Silver Horde are appalled at the use of poisoned food, because while the approved barbarian method of trickery is inviting your enemy over to a feast, get him roaring drunk then kill him (any barbarian stupid enough to fall for it deserving it), you never know when you might get hungry yourself.
 * It shows up in The Count of Monte Cristo. Once in a story about the Borgia, and as the murder weapon of.
 * Much discussed in the Dorothy L. Sayers novel Strong Poison. Mystery novelist Harriet Vane is tried for poisoning her lover Phillip Boyes with arsenic. Despite a mistrial, she is widely assumed to be guilty and vilified on that account. Norman Urquhart's cook comments on this to Bunter, "...but the horrors of slow poisoning, that's the work of a fiend."
 * In Raiders of Gor one of the five claimants to being the ruler of the city-state of Port Kar is a skilled poisoner and is looked down upon. (He's also a bit fey, which doesn't help.) After being exiled from the city, in Hunters of Gor he secretly supplies poisoned swords to enemy fighters, and they poison Tarl, paralyzing him. In Maurauders of Gor the leader of those enemy fighters approaches Tarl to give him an antidote; when the king of their city-state had learned of the treachery he forced the other man to create an antidote, then poisoned him to test it. On Gor generally, poison is dismissed as a woman's weapon.
 * In Dune Feyd Harkonnen is shown using poison frequently: weakening his slave gladiators so he always wins his fights, attempting to poison his uncle the Baron through the thigh of a sex slave, and using a secret poison needle in his belt buckle in his combat against Paul Mua'dib.
 * The Eyes of the Dragon has sorceror Flagg utilize an excruciating poison (one that he's even wary about) on the king to put his younger Enfant Terrible son on the throne, framing the king's elder son for the crime. Why? Because he can.
 * Subverted in an obscure 1980's series of historical novels by author William Morrell. The heroine (a Dutch noblewoman who has been trained in ninjutsu while living in Japan) uses poison to kill an evil Spanish nobleman that she is being forced to marry.
 * Also done in the first book in The Mark Of The Lion series, where young noblewoman Julia poisons her violently abusive suitor to be rid of him. It's tempting to count this as an inversion since he was such a vicious brute, but considering Julia goes on to condemn the heroine Hadassah to be fed to lions in the Colosseum, it's still a pretty straight example (at least until both women get better in the second book).
 * Inverted in Agatha Christie's Halloween Party. When Hercule Poirot asks the gentle, kind Miranda how she would kill someone, she replies that she would use poison--specifically a sleeping draught--because she wouldn't want to cause anyone any pain.

Live Action TV

 * Star Trek: The Next Generation episode "Reunion": Chancellor K'mpok announces he's dying, murdered by a slow-acting poison. It's stated that a Klingon who kills without showing his face has no honor and must not be allowed to lead the Empire. Picard is tasked with finding the killer and preventing him ascending to the Chancellorship.
 * Inverted in Merlin in which it is heroic Merlin who uses poison to try and kill Morgana, thus breaking a near-fatal spell over Camelot that she was inadvertently causing. Played straight later, when Morgana uses poison to kill a witness to her Face Heel Turn.

Tabletop RPG
"It is also likely that the DM will establish sanctions regarding the use of poisons on a continuing basis, i.e. characters of good alignment cannot use such toxic substances as it constitutes foul and unfair practice; or characters found with poisoned weapons will be immediately slain and their corpses burned and ashes scattered. In a similar vein, most communities view poisoning and poisons as highly undesirable due to the difficulty of protecting against ingestion of such fatal substances. Any individual (or group) making indiscriminate use of poison will have social pressure and/or legal action brought against him or her."
 * Dungeons and Dragons: The use of poison in the game, while not an evil act in itself, is not a good act, and definitely not a lawful one (though Lawful Evil types like Asmodeus might disagree).
 * In AD&D 1st Edition Assassins (who were always Evil) had special abilities with learning about and using poisons.
 * Evil clerics could use poison, non-evil clerics could not. Likewise, evil bards could use poison, non-evil ones couldn't.
 * Any non-assassin NPC would assume anyone with Poisoned Weapons were assassins and attack them, call for the city watch or both. Meanwhile assassins won't like when people break their "monopoly."
 * Some suggestions on how DM's should handle poison use:


 * Use of a Dagger of Venom (which injected poison) could cause alignment problems for Good aligned characters.
 * In 2nd Edition all of the references above were removed except for the Dagger of Venom. Now a few Good critters like Couatl, used lethal poisons too.
 * In 3rd Edition, using poison is still generally evil. Like previous editions, Poison Use as an ability is almost always exclusive to evil classes.
 * Avengers are like the Assassin class in every way except the flavor is "duty-bound superspy" and must be non-Chaotic.
 * Eberron's Warforged don't get the ability directly, but are immune to poison, duplicating any effect of the ability.
 * Book of Exalted Deeds introduces "ravages," which have exactly the same effect as poisons, except that they are okay because they work by reacting to the evil in a creature, rather than the way many poisons tend to work.
 * A non-lethal knockout venom exists that is the exception: It has no worse side effects than "unconscious for 2d4 hours", and the books specifically mention that even paladins could use that one with little moral quandary, provided the intention is to knock someone out rather than kill them (like capturing a criminal for courts). Of course, in a fine bit of Irony, it's called Drow poison and is relatively unknown on the surface: The Drow use it for live captures of slaves. For that matter, Drow can get Poison Use from alignment free classes, but Drow are Chaotic Evil (except the throng of Chaotic Good rebels struggling to throw off the reputation of their Evil brethren, who still get the perks).
 * In 4th Edition, poison isn't evil any more, and anyone can use it with impunity.
 * The Always Chaotic Evil Anti-Paladin class in an early Dragon Magazine article. An Anti-Paladin was an "aficionado of the fine art of poisoning," who considered "poisoning to be both an aesthetic pleasure and a means of artistic expression." He used poison at every opportunity, including to test a new poison just distilled for him, to determine if his stock of vintage poisons was still potent or simply to see if he can get away with it.
 * Dark Sun as a Darker and Edgier setting was one of few exclusions -- bards learn to use poisons without any Character Alignment considerations.

Video Games

 * In Fire Emblem, only enemies can use Poison weapons, unless you somehow manage to swipe one off them (and in some games they end reverting to normal weapons if you do that). Averted in Radiant Dawn, after defeating a lategame boss with a poisoning magic tome you get it and can use it to poison enemies.
 * In Fire Emblem: Radiant Dawn, Izuka urges the party to capture a nearby prison camp by dumping poisons in the camp's water supply. The protagonists disprove, claiming they will lose the support of the citizenry for it, but makes no sense from a strategic stand point (the mission is to liberate the prisoners to gain a manpower boost, which is impossible when they are dead.).
 * Averted and played straight in Pokémon: Team Rocket uses mainly poison-types, but there's also a Poison-type Gym Leader in Pokémon Red and Blue (the only one in the entire series in fact, not counting his daughter from Pokémon Gold and Silver) and nothing stops you from using Poison types, aside from their general crappiness in battle.
 * Also, as of Generation V, there are actually no Poison-type Legendary Pokemon, not counting Arceus holding the Poison plate, while every other type has at least one Legendary.
 * In addition, in the first games the only ghost types were also poison types and they were somewhat evil (possessing channelers in the Lavender Tower).
 * In World of Warcraft, the rogue class can use Poisoned Weapons. The only two playable races who are unable to be the rogue class are the Tauren on the Horde side and the Draenei on the Alliance side. Each of these two races is the most noble race among their respective faction.
 * Averted in The Reconstruction, plenty of characters with Noxious skills and affinities are perfectly nice people.
 * In the Ace Attorney series, there are at least three incidents involving poison and beverages. There is also a case involving poisoned  and a case involving poisoned  . All are the work of villains. Phoenix Wright says at one point that the two things he cannot forgive are poisoning and betrayal.
 * In Battle for Wesnoth, only the orcs and undead have the ability to poison.
 * Zig Zagged in Assassin's Creed. In the first game, the eponymous creed specifically forbids the use of poison; in the second game, however, it's stated that the Assassins have adopted the use of poison in order to adapt to changing times. (Twisting the trope further is the fact that poison is one of the less subtle weapons in the protagonist's arsenal - a poisoned foe will go berserk and attack everyone around him before dying!)
 * In Final Fantasy VI, Kefka's use of poison at Doma (Read: "mass murder of an entire city"), even in war, is the point that the Empire's soldiers and citizens consider him to have crossed the Moral Event Horizon. That said, your characters can learn Poison-elemental magic fine.
 * Just like the ones in Dungeons and Dragons, Egoboo paladins cannot use poison.
 * In Emperor Battle for Dune, both the evil Harkonnen and the decidedly amoral Ordos use weapons based on toxins and poison, as do the tleilaxu. The noble Atreides and the fremen, meanwhile, do not.

Webcomics

 * Inverted in Axe Cop, where it's the good guy who poisons everyone. He seems to have a poison for every villain he comes across with some bizarre method to get it into them.
