* Celesto Morgan in ''Webcomic/DominicDeegan: Oracle for Hire''. Compare him to the far more ruthless (and detestable) KnightTemplar Raf Maliksh, who tries to kill Celesto for being insufficiently fanatical.
* {{MAG ISA}}: [[http://mag-isa.thecomicseries.com/comics/pl/119653 The school shooters in this comic are well-intentioned extremists]]. They honestly believe that by [[http://mag-isa.thecomicseries.com/comics/pl/119712 shooting up a school]], they help create a world of love and peace.
* ''{{Webcomic/Zoophobia}}'''s Adina believes that she is purifying the world by [[spoiler: destroying those she deems "evil", which more-than-often includes those who ''aren't'' truly evil.]]
* As shown somewhat earlier in the strip, Miranda West of ''Webcomic/TheWotch'' walks full stride into Well Intentioned Extremity in a recent arc, where she punishes [[SchoolNewspaperNewsHound Ivan]] for being too intrusive in his desire to discover Anne's secrets, also condemns two innocents, and then refuses Ivan's plea that he has (apparently) learned his lesson, as well as refusing to help the ones who had nothing to do with her concerns, [[http://www.thewotch.com/?epDate=2008-12-23 threatening him]] when he calls her out on it. But her status as a WellIntentionedExtremist comes not just from her actions, but also from [[http://www.thewotch.com/?epDate=2009-01-09 her attempt to justify it]] to her familiar (and herself).
* Professor Broadshouders in ''[[http://zebragirl.keenspot.com Zebra Girl]]'' has made it his life's mission to rid the world of demons - and doesn't care who he has to hurt, damn, or kill to get the job done. Up to and including himself.
* ''Webcomic/GirlGenius'':
** [[JustTheFirstCitizen Baron]] [[EmperorScientist Wulfenbach,]] absolute ruler of Europa. He demands obedience of his subjects, kidnaps the children of notable [[MadScientist Sparks]] to his floating citadel in the sky, sends criminals and troublemakers to the [[GeniusLoci Castle]] [[DeathTrap Heterodyne]] to repair it, [[SnipeHunt despite nobody even possibly knowing how to,]] and has burned entire towns down to the ground to contain unmanageable problems within. He's also absolutely fanatical about keeping the Heterodyne bloodline under control, which puts him at odds with the protagonist Agatha, herself the last known heir of the family. The thing is, he has a point. Prior to his taking control, Europa was a chaotic, feudal place of madness where most Sparks ran wildly and warred against each other with their insane creations, the worst of which included the exceptionally powerful Heterodyne family, which for at least fifteen hundred years had been, with two very notable exceptions, irredeemably evil warmongers singlehandedly capable of bringing Europa into ruin. Everything Baron Wulfenbach has done, however horrific, has been to restore peace and order to the country, [[TheExtremistWasRight and he did a damn good job of it too.]] [[spoiler:Not only that, but once he [[TimeStandsStill freezes himself along with the entirety of Mechanicsburg]] in a bid to keep Agatha from reclaiming the seat of her power, Europa quickly descends once again into a terrible anarchy unmatched by any before.]]
** Othar Tryggvassen, GentlemanAdventurer!, from the same series. He has the same goal as the Baron but a different method: [[GottaKillEmAll He plans to kill every Spark in the world]], [[NoPlaceForMeThere ending with himself]], due to the sorry state Sparks have left the normal folks of Europa in. As a result he's a hero to the common folk and non-sparks, while the sparks (including our protagonists) all despise him and [[RunningGag tend to throw him out of airships]].
** Pretty much EVERY Spark (who isn't already a full-time villain) is, at one time or another, one of these. It goes with the Sparkiness. Even Agatha. As demonstrated [[http://www.girlgeniusonline.com/comic.php?date=20070216 here.]]
* In ''Webcomic/KidRadd'', [[spoiler:GI Guy]] believes that humans and sprites are too far predisposed to hurting each other to hope for peaceful existence, and that a mercy-genocide is in order to stop the suffering.
-->Radd: He was just... well, like a lot of madmen. Somewhat accurate view of the problem, really insane view of the solution.
* ''Webcomic/TheOrderOfTheStick'':
** Redcloak, if one reads ''Start Of Darkness'', falls squarely into this. He wants to improve life for the goblinoid races, but attempts to do so by putting down the other humanoids via divine blackmail, instead of by actually helping the goblins improve their lot.
** Even more so, Miko Miyazaki. A case study in what Lawful Good can do, when taken to its extremes. Justice untempered with Mercy, blind to the possibility that she could ever be wrong.
** On the heroic side, Vaarsivuus is getting there as well in recent comics. At this rate, (s)he'll end up like [[HeroicComedicSociopath Belkar]]...
*** ...quite possibly [[http://www.giantitp.com/comics/oots0331.html by saying the right four words to the right being at the right time for all the wrong reasons.]]
*** [[spoiler:[[http://www.giantitp.com/comics/oots0634.html Confirmed.]]]]
*** [[spoiler: Fixed after a TheReasonYouSuckSpeech from big bad Xykon makes him/her realise that might does not make right]].
* It can be argued that [=VespAvenger=] from ''Webcomic/QuestionableContent'' is a well intentioned extremist in the punishment she doles out to [[http://questionablecontent.net/view.php?comic=743men those who mistreat their girlfriends.]]
** However, Faye, Dora, and Marten then quickly point out how wrong this is by asking her what she'd think if a ''man'' [[DoubleStandard did what she did]] to women who mistreat their boyfriends. She'd ask him out. And then she orders her Vespa-bot to shoot Dora and Faye, with the lasers set to "disfigure".
* It's been stated that Roxy Lalonde from ''Webcomic/{{Homestuck}}'' doesn't really plan her actions often, and they tend to do more harm than good. But she usually means well and enjoys helping her friends, even though she's done things such as blowing up her best friend's computer and coercing her into revealing her feelings for Jake.
** A clear example from Homestuck is Aranea, who wishes to create an alternate timeline where the BigBad never comes to power, and then use her unique abilities to make that timeline become the main universe. Of course, in order to do so, she is willing to kill anyone that gets in the way, including those opposed to the very Big Bad she's trying to stop.
* [[spoiler: Ian Samael]] from ''Webcomic/ErrantStory'' comes from a culture where Elven oppression is common and many Elves wouldn't think twice before wiping him out. His goal to keep his people from being hunted down by Elves is fine; pity that he tries to do so by [[spoiler: attempting to wipe out the Elves himself.]]
* Darkbringer from ''{{Webcomic/Lightbringer}}'' strongly believes that the only way to fight evil is to [[LogicBomb embrace its ways,]] abandon all hope, and give up himself to darkness and despair. He believes that Lightbringer's actions give people false hope, so he wants to kill him.
* SUEPR Team One, from ''Webcomic/CityOfReality'', attempts to protect Reality's MarySueTopia by destroying the entirety of the neighboring World of Magic, which has threatened to wreck their way of life. The protagonists are forced to try to stop them, despite nearly falling victim to the very same cynicism.
* Weijuaru of ''Webcomic/{{Juathuur}}'' basically wants to make every juathuur a god, because that would mean absolute freedom.
* The robot Blunt in ''Webcomic/{{Freefall}}''. Just wants to protect humanity...[[spoiler:and has no problems with a plan to lobotomise millions of robots to remove the chance that any of them could harm a human]].
* This is exactly how the main character was going to turn out in ''Webcomic/ToPreventWorldPeace''. Until her FaceHeelTurn, anyway.
** In fact, before she goes AntiVillain [[VillainProtagonist Protagonist]], '''all''' the {{Magical Girl}}s are destined to turn out like this.
* Parodied in [[http://www.pvponline.com/comic/2009/09/08/recipe-for-disaster this]] ''Webcomics/PvP'' strip.
* Psionic Minmax in ''Webcomic/{{Goblins}}'' wants to reduce the amount of suffering in the world... and considers [[ApocalypseHow triggering a Class 6 Metaphysical Annihilation]], [[OmnicidalManiac completely unmaking reality]] so that suffering doesn't have anywhere to take place, to be a perfectly reasonable way of achieving that goal.
