History WellIntentionedExtremist / AnimeAndManga

** [[TheChessmaster Lelouch vi Britannia]] is actually a well-intentioned extremist. His primary goal is overthrowing the oppressive SocialDarwinist [[TheEmpire Britannian Empire]] because it tramples on those who are weak or kind-hearted. Oh, and there's lots of mass murder of its third-class citizens and anyone who lives in a country that it wants to take over. In a subversion, even he has trouble stomaching some of the steps it takes to achieve his goal, as seen when [[spoiler:he becomes physically sick after killing his half-brother Clovis, who fully supported the Empire -- and more than that, killed several thousand people to keep his illegal experiments hidden -- and nearly breaks down after unintentionally making his beloved half-sister [[RoseHairedSweetie Euphemia]] go AxCrazy, so [[KillTheCutie Lelouch had to kill her]] and make the best out of a bad situation.]] In all, he often has a choice between a terrible, terrible thing, and an even more terrible thing.

** Unfortunately, Lelouch [[spoiler:throws the "Well-Intentioned" out of Extremist when he becomes a despotic overlord and Emperor of the world, and moves to execute any and all political opponents. Oh, wait, no, that's how he '''wants''' to portray himself, so that once the world's hate is concentrated on him, he can arrange for himself to be publicly assassinated by his friend Suzaku, ending the chain of hatred by setting up the infrastructures and political status quos he had set up earlier himself and [[ThanatosGambit achieve world peace through his death]], symbolically killing the world's hatred with him.]]

* ''Manhwa/IWish'': Dee comes across as this. Since she's a witch, she studies like crazy to improve her abilities in repeated attempts to help make the world a better place for people. Unfortunately, her hyper and rather carefree attitude about her powers often leads to her magic failing or ultimately making things worse. While she wants to help K by having him experience love through a LovePotion, she tried it on all of her servants first and it resulted in them becoming obsessed with her, to the point that they'll [[{{Yandere}} kill her]]. Fortunately, once [[spoiler:Wye goes through a convoluted plan to get himself temporarily killed and Dee's powers become better]], Dee learns the lesson that [[WithGreatPowerComesGreatResponsibility using her magic can cause severe consequences]] and she isn't as carefree about it anymore.

** The truly faithful Father Pucci of ''[[Manga/JoJosBizarreAdventureStoneOcean Stone Ocean]]'', whose ultimate goal is [[spoiler:to reach the "Heaven" he heard his mentor Dio talk about. He'll do anything and sacrifice anyone to get to it, and apparently, he does: he rewinds, remakes, and resurrects the world (that he completely messed up), but is killed before he can join it.]]

** ''[[Anime/MobileSuitGundam00 Gundam 00]]'''s Celestial Being. The whole point of their actions is to beat up/kill any human factions who wish to wage war against each other. They get better about this as the story progresses, and become much more selective in their targets. They even ally with an anti-government military force in the second season. Their overall goal of eliminating conflict through force remains, though. [[spoiler: It was all ThePlan by Schenberg to unite humanity in order to prepare them against an AlienInvasion.]]

''[[Anime/MobileSuitGundamWing Gundam Wing]]'':

** Char Aznable from the first ''Anime/MobileSuitGundam'' series, or, to be more precise, ''[[Anime/MobileSuitGundamCharsCounterattack Char's Counterattack]]'', in which Char tries to make the Earth uninhabitable to force the population to migrate into space, which he believes will prevent wars by making everyone a [[EvolutionaryLevels Newtype]]
** PLANT Chairman Gilbert Durandal in ''[[Anime/MobileSuitGundamSEEDDestiny Gundam SEED Destiny]]'', inspired by Rau Le Creuset's inability to understand his own existence (which drove him insane and allowed him to nearly wipe out the human race), decides that human conflict stems from their dissatisfaction with their own roles and abilities, and attempts to implement an utopian society through the Destiny Plan, which would craft a world civilization under genetic determinism. To this end, he is perfectly willing to manipulate the masses, assassinate his political opponents, destroy countries, and use superweapons, all while maintaining [[AffablyEvil an extremely high level of charisma]]. Durandal also believes that uniting the world will prevent future Le Creusets from having any real success. After all, if there's only one nation, there won't be different factions for people like [[ManipulativeBastard Rau]] to set against one another. To his credit, his goals also included the elimination of LOGOS, a military-industrial complex that was perpetuating WarForFunAndProfit (mostly profit, since they owned most/all of the mobile suit manufacturers).
** ''[[Anime/MobileSuitGundamWing Gundam Wing]]'':
*** It's often forgotten that the protagonists are outright called terrorists, though, unlike most, they limit their attacks to the military and have no intention of harming innocent civilians. The line still gets crossed a few times, though: Heero destroys a plane full of OZ leaders ([[NiceJobBreakingItHero only they were actually planning a peace treaty with the colonies, and he was tricked into shooting them down without knowing that fact]]), and Wu Fei blows up a barracks full of sleeping soldiers ([[NeverLiveItDown sadly, people tend to gloss over his obvious displeasure with this act]]).
*** Zechs Merquise/Milliardo Peacecraft becomes convinced, in the final episodes of the anime, that the only way to end humanity's penchant for war was to [[EarthShatteringKaboom destroy the Earth]], the cradle of humanity's bloody history, as he believed that the people of the space colonies were purer in purpose in regard to peace than those who lived on Earth. More than that, though, it was an idea hatched by Zechs and Treize to show humanity a conflict so bloody and violent that humanity would lose the will to fight ever again. It's sort of like an intentionally planned World War I, and actually ends with the same results: mainly, that people DO lose the will to fight...for a while.
