''The entropy of a fictional system whose writer is not in emotional equilibrium will tend to increase over time, approaching a maximum value at the writer's emotional equilibrium.''

There's no other way to say it: writers like killing and destroying. Nothing makes them happier than having people die or StuffBlowingUp. (In their writing, not in their real-world behavior. We're sure about this. [[http://www.guardian.co.uk/books/2007/sep/16/crimebooks.features Mostly]].) It's the quickest way to get drama, too.

Unfortunately, writers cannot destroy all their fictional creations without ruining the story. Some of those creations have ContractualImmortality. Even when they don't, killing characters off or nuking cities can change the flow of a story in rather unfortunate ways. And [[KillEmAll destroying everything]] means there's no more story, and thus no more paychecks for the writer.

As a result, when there ''is'' anything expendable, writers will expend it. If the writer can bring people back to life by pushing the ResetButton, then people will die as long as the button is there. If a city has been evacuated, that city will go down in flames. Atomic flames, preferably. [[ThrowAwayCountry If it hasn't been evacuated, the writers can blow it up anyway if no named characters are there.]] It's not like readers will be upset, right? After all, AMillionIsAStatistic. And a character in a {{Prequel}} that wasnít in the original work? Donít get too attached to them.

The less often the writers get to do this, the more pyrotechnics they pack in. When everything is expendable (like in a show with NegativeContinuity), the writers will increase their system's entropy at a leisurely pace. [[OnceAnEpisode One death an episode or so]] will do. If almost everything has ContractualImmortality, then killable characters and inflammable places are rare treats, and the writers will spring on them like the proverbial hungry wolves on a sheep.

At times, some writers seem to be working out their stress by destroying fictional people and places. The carnage is always greatest at the moment the writer gets better, since they will increase the entropy until their self-therapy finally works. Needless to say, CreatorBreakdown and DarkerAndEdgier almost inevitably leads to higher entropy.

This is the reason for the following tropes:
* AnyoneCanDie
* ClimacticBattleResurrection
* CListFodder
* CloningBlues
* ConvenientlyEmptyBuilding
* ExpendableAlternateUniverse
* GoodThingYouCanHeal
* ItsGoingDown
* KillEmAll
* OpeningACanOfClones
* ResetButton
* StuffedIntoTheFridge
* TonightSomeoneDies
* ThrowAwayCountry

The Trope Name is a reference to the Second Law of Thermodynamics, which states that everything in nature increasingly trends towards disorder (or entropy, to be more accurate.) A similar naming convention was used for the FirstLawOfMetafictionalThermodynamics.


[[folder:Anime and Manga]]
* ''Anime/NeonGenesisEvangelion'' is actually famous for its CreatorBreakdown and subsequent [[spoiler: KillEmAll ending]]. It's a great example of this trope even before the ending, with more and more damage being done to Tokyo 3 and the cast each passing episode. This could also be tied to Creator/HideakiAnno's building depression.
* ''Anime/PuellaMagiMadokaMagica'' references the actual Second Law of Thermodynamics in relation to its own [[spoiler:AnyoneCanDie and FromBadToWorse plot]].

[[folder:Comic Books]]
* [[UsefulNotes/TheDarkAgeOfComicBooks Dark Age]] comics seemed to go through a period when blowing up or wrecking cities, or killing off characters, was the flavor of the decade. Especially [[Franchise/TheDCU DC]] with its Coast City debacle, Gotham City's "No Man's Land", and three-quarters of Metropolis being wrecked. And Montevideo (wonder how the real city took the news?). The capitol of Nebraska gets nuked by an alien thingy, with the after effects blowing over half of Smallville. They seemed to be reverting to this again around ''ComicBook/InfiniteCrisis'' with several [[ThrowAwayCountry throw-away countries]] being violently depopulated and Bludhaven drowning in toxic chemicals/going boom.
** Random worldwide massacres. Maggedon comes along, thousands croak in the affects of his defeat. Cyborg comes back to life, eats the moon, the world shakes and shimmies and buildings collapse. ''ComicBook/InfiniteCrisis'' had hurricanes chowing down all over the world, entire cities flood and nearly every volcano ''ever'' blowing its top.
** Gotham City in the comics. Every time ComicBook/TheJoker slips loose from Arkham Asylum or the Scarecrow gets his crazy on or heck, there's just a party, something shows up and turns hundreds of people into crispy fried corpses. And the police officers...does anyone train them? They go down dead when looked at hard.
** During the mostly-Superman event ComicBook/OurWorldsAtWar, the city of Topeka, Kansas was completely destroyed. Unlike Marvel and their New York setting, DC apparently didn't care whether the "Topeka" depicted in the book actually resembled the real life Topeka.
* The Franchise/MarvelUniverse also had its bloodbaths, with Manhattan being badly damaged by Onslaught (and later, mostly leveled by Magneto), Carnage and his troops turning the streets into killing fields and the island of Genosha and its sixteen million mutants being killed.
** For this and many other disasters, the regular Marvel Universe has 'Damage Control', a company that can apparently rebuild entire cities just by ... um ... being awesome. Or something. Don't look too closely.
** ComicBook/UltimateMarvel has had ''millions'' killed by the various {{alien invasion}}s (especially the worldwide mass suicides during Ultimate Galactus), Magneto's Brotherhood attacks, Proteus' RealityWarper rampage, and the Liberators' brief conquest of the United States.
** Let's not forget the ComicBook/WorldWarHulk arc, where The Hulk caused a ludicrous amount of damage to UsefulNotes/NewYorkCity. Admittedly, it was (somewhat) justified. Well, kinda. Ok, not really. He does ask for New York to be evacuated and this is while he's almost as mad as he can get due to his pregnant wife having been just killed. [[spoiler: Regular people even sympathize and cheer him on while he brutalizes and humiliates the heroes he blames for this, Doctor Strange, Iron Man, Black Bolt, and Mister Fantastic, then spares them claiming he wants justice not vengeance.]]
** It gets bad whenever Marvel has the heavier cosmic characters go at it. In one story simply waking the ruling Celestial destroyed two galaxies. Even planet eater Galactus [[BringMyBrownPants was having trouble holding it in]].
** Infinity Gauntlet was an example of the reset button. ComicBook/IronMan loses his head, ComicBook/SpiderMan's head is crushed, [[ComicBook/TheMightyThor Thor]] is turned to stone, half the universe suddenly dies etc.
** Early in ''ComicBook/SecretWars'', the Beyonder destroys everything in a galaxy except for one star.
* ''ComicBook/JudgeDredd'' also followed this trend; from the early comics, where a Judge would risk his life to save a single child, to later when it was acceptable behavior to gun down one innocent if it meant hitting the two perps next to them, to some storylines where wholesale carnage was status quo. ''Graveyard Shift'' was about the riots and carnage in Mega-City that cost thousands of lives and was assumed to happen ''nightly''.

* ''Film/ResidentEvilApocalypse'': Alice and company are safely escaping in the helicopter. 99.44% of the rest of the city is zombies anyway. [[spoiler: So Umbrella Corp nukes it.]]
* ''Film/TheReturnOfTheLivingDead'' The army has no idea how to get rid of the zombies. They bomb the whole town. This proves to be ill-advised.
* Subverted in ''Film/{{Outbreak}}''. The viewers were given plenty of information about the residents of the town about to be bombed. So naturally the day is saved.
* In ''Film/AliensVsPredatorRequiem'', [[spoiler:TheMenInBlack deal with the Alien infestation by blowing up the entire town, leaving only the heroes who were smart enough to ignore the government advice to stay in the position and wait for evacuation.]]
* In relation to the comics above, ''Film/TheDarkKnight'' is an exception. In the comics, it's a rare, rare person who escapes the attentions of ComicBook/TheJoker alive, much less un-maimed. In the movie, many do so, even cops who are usually the first to go. ''Film/TheDarkKnight'' and ''Film/BatmanBegins'' seem to be working very hard to present Batman and his world in a '[[{{Demythtification}} realistic]]' setting. In a superheroic setting where the main characters are far more powerful and capable than normal humans, ComicBook/TheJoker can go omnicidal easily enough. But when you present Joker as a 'realistic' psycho, he's more limited.
* Anything not critical (anymore) to the plot in ''Film/{{Armageddon}}'' blows up. The spacecraft visit MIR for refueling; It blows up right after they're done. There are 2 spacecrafts; One crashes. The drill of the crashed spacecraft survives; The one from the other spacecraft blows up.
* ''Film/RogueOne'' heartily subscribes to the mentality that "anything that can be expended, will be expended." As such, most unnamed characters, whether they're rebels or a stormtroopers, are killed in droves, often by violent explosives or waves of gunfire. And further than that, [[spoiler:nearly everything new to this movie is destroyed; Jedha city, the Scarif base, the entire Rogue One crew, Orson Krennic, the Erso family, Saw Gererra, and all of Green Squadron, are all gone while the characters from ''A New Hope'' and on are safe because they have to be.]]

* WordOfGod states that this is the reason [[spoiler: half the cast gets blown up]] in ''Literature/TheStand''.
* E M Dutch does this in ''Literature/AnotherDayAnotherNightmare''. Every time she reached a plot hole, or suffered from writers' block, she killed someone off. In increasingly imaginative ways, including a flock of exploding pink [[strike:budgies]] parakeets. I really wish I was kidding. Apparently, the (as yet unpublished) sequel(s) contains more of the same, to the extent that the author has stated she can't write another in the series because everyone with unresolved plot has already been killed off...
* Creator/DouglasAdams was having a really horrible year when he wrote ''Literature/MostlyHarmless'', so he not only [[spoiler:makes Arthur Dent lose his love interest Fenchurch early in the book]], but by the end of the book he actually [[spoiler:blows up the whole world again (it having been blown up once already in ''Literature/TheHitchhikersGuideToTheGalaxy1''), with all the main characters on it]].
* One of the earliest scenes in the first ''Literature/{{Discworld}}'' novel, ''Discworld/TheColourOfMagic,'' had the main characters accidentally burn down the city of Ankh-Morpork. Pratchett later talked about how this would be impossible to do subsequently, what with all the main characters, side-characters and even just general culture that sprang up in the forty-odd books since.
* This is the reason Creator/GeorgeOrwell's (a.k.a. Eric Arthur Blair) famous dystopian novel ''Literature/NineteenEightyFour'' has such a downer ending. Mr. Orwell was dying from tuberculosis at the time he wrote the book.

[[folder:Live Action TV]]
* ''Series/TwentyFour'' without a doubt. The writers seem to create characters, buildings, and whole cities for the express purpose of killing or destroying them later.
* It becomes clear that there are so many people with abilities in ''Series/{{Heroes}}'' so that the writers have lots of cool people to kill off in shocking ways. They take it one step further with their alternate futures where something is always about to be blown-up, a virus will kill everyone, or some other cataclysm will take place, but thanks to the ResetButton, it never comes to pass. This of course allows for more alternate timelines to be created and averted.
* Beginning as a strange but mostly plausible story about what happens to retired secret agents, ''Series/ThePrisoner'' gets more bizarre over time until the last episode leaves viewers utterly dumbfounded.
* The intro sequence of ''Series/SevenDays'' (where the entire plot -is- the ResetButton) uses a shot of missiles striking the White House. That was in the pilot episode, and things only get more dangerous from there.
* Every AlternateUniverse episode of ''Series/StargateSG1'', most prominently in "There But For The Grace Of God," in which all main characters bar Daniel Jackson are killed and the Earth is taken over by Apophis and 2010 in which all main characters are killed and 90% of Earth's population has been sterilized by an alien race that plans to make us slaves.
** Martin Gero, one of the writers on ''Series/StargateAtlantis'' has said in commentaries that he killed someone in every episode he wrote in season one since he was alone in a new city and girlfriend-less. Following with the trope, when he wrote season two episodes he was happy and in love so the carnage was scaled back.
** Let's not forget that every member of [=SG1=] was also killed at one point (and later brought back to life). Special mention goes to Daniel who was killed off the most.
* ''Series/BuffyTheVampireSlayer'' liked to end seasons this way once a particular set became expendable: See Sunnydale High, the Initiative, to a lesser extent The Magic Box, and in the series finale the entire city of Sunnydale.
** Story-wise, the entire city was designed so expendable humans could be safely eaten.
* Granted, the point of ''Series/DoctorWho'''s "[[Recap/DoctorWhoS30E11TurnLeft Turn Left]]" is to show how hopeless Earth would be in a timeline without the Doctor, but come on. The characters from ''Torchwood'' or ''The Sarah Jane Adventures'' have plenty of PlotArmor on their own shows, but as soon as they're thrown into an alternate timeline, the writers can't help but kill off those entire casts.

[[folder:Western Animation]]
* In ''WesternAnimation/AquaTeenHungerForce'', anything that touches Master Shake and then a surface (wall, ceiling, or floor) will explode. [[ConvectionSchmonvection With no effects on anything around it]]. [[EpilepticTrees Fans often speculate that this is Shake's superpower]]. Fortunately (for Meat Wad at least), neither Shake nor anybody else seem to really notice this effect.
