Sora from .hack//SIGN, after repeatedly being scolded by Silver Knight for not taking anything seriously and just being an ass, replies along the lines that they're in a game and the point is to not take it seriously and have fun. Even though there's a lot more going on than it just being a game, and while he is a complete dick about how he has fun being a Player KillingTroll, what he says indeed rings true. Silver Knight actually concedes the point.
In Accel World, during the climax of the first volume, Haru learns that his childhood friend, Taku, is actually Cyan Pile, the Burst Linker who's hunting his mentor Kuroyukihime for the point bounty on her, and that he also put a backdoor program in their mutual friend (as well as his girlfriend) Chiyu's Neurolinker to spy on her. Taku reveals that he's dating Chiyu so that she doesn't spend her life looking after Haru, and Haru, despite finding his point difficult to accept, admits that it's not entirely without basis.
In Aggretsuko, Retsuko's mother is extremely overbearing and hypocritical about getting Retsuko to go on dates and find a match, especially since she shunned matchmakers herself when she was Retsuko's age. However, she does have a point when she bluntly tells Retsuko she needs to stop treating men like sushi on a conveyor belt and assuming they will always wait for her to get over her insecurities because they'll move on and find someone else, which is exactly what happens when Retsuko meets Shirota — Retsuko, despite liking him, finds excuses not to see him again due to her indecisiveness. Later on, she has a low moment and brings up Shirota and her mother tells Retsuko that he's already dating another woman, leaving Retsuko crushed by the news.
Angel Sanctuary: Setsuna and Sara's mother. Her son gets ignored, snapped at, and blamed for getting Sara into dangerous situations, and does her best to separate her two children. And Setsuna agrees with her on a level because they both know that he has incestuous feelings for Sara, and keeping them apart will keep Sara 'safe' from him.
In Area 88, Kanzaki of all people warns Ryoko that her fixation on Shin is pathological. He tells Ryoko that her obsession with an absentee Shin is reminiscent of his mother's obsession with his estranged father, which ended with his mother's suicide. Kanzaki's observation was validated in later manga issues that did not make it stateside. Ryoko unsuccessfully attempted suicide after Shin broke her heart over the phone.
Ryoko: I feel bad about saying this, but I think your mother must have been a very weak person. To end up like that, I mean. Even if I were in her situation and lost my man. As long as I had the memory of the love I shared, I'm sure I would be able to handle it. And I would never involve a small child in my problems. Kanzaki: It's easy to have such an idealistic attitude. But, would your attitude hold up if you were really faced with the same kind of situation? ... Shin has been missing a long time. And you don't know whether he's alive or dead. Yet, you still love him. In retrospect, is your situation any different?
Some also say that Ryoko speaking so harshly about the dead is in and of itself a Jerkass move. But can any parent who commits suicide and leaves a child behind truly be considered a responsible individual?
In Ascendance of a Bookworm Lutz's father is deadset against him becoming a merchant, which was already a compromise for Lutz who wanted to be a traveling salesman. He refuses to even discuss it with his son, seemingly determined to have him follow in his steps as a carpenter. Yet when his father is brought in to talk about it, the points he makes are very reasonable and even right for the most part, which leaves his son at rather a loss.
Levi's Brutal Honesty, despite often making him appear like a jerk, is usually proven right. During Eren's trial, he openly criticizes the merchants for being greedy pigs, but he is absolutely correct since they care more about their safety and business than caring about starving refugees, especially since one merchant deliberately blocked off an escape route with his goods and flat-out told Mikasa to her face that she and the rest of the Survey Corps solely exist to die so people like him can live. He also harshly ordered Eren to figure out a way to transform into a Titan because if he didn't, then any chance of reclaiming Wall Maria was gone, and there would be a high possibility that Eren would be handed over to the Military Police Brigade who would then execute him.
Galliard snidely tells Reiner if he was the one to inherit the Armored Titan instead of the latter, their mission to the Paradis island would have been more successful and even asked the latter if they had accomplished anything at all or if they needed to be saved all the time. While this was a horrible thing to say to someone who is suffering from PTSD, it was hard to deny that Reiner did have to be constantly saved by others, such as Marcel pushing Reiner away from being eaten by Ymir, Bertolt transforming over Reiner and Eren so they could capture Eren, Ymir saving him and Bertolt from Titans, Zeke and Pieck rescuing him in the battle of Shiganshima. Reiner says, in almost as many words, that Galliard is completely right. Though it's debatable whether Galliard would have done any better if he was sent instead.
Floch bluntly states that he and everyone else wishes Erwin had been saved instead of Armin, to the latter's face. He also berates Eren, Mikasa, and Levi for being irrational and acting like children, going with their emotions rather than putting humanity first. He also accuses Eren of always thinking he's in the right, basically accusing him of Moral Myopia. While Floch's undoubtedly an asshole, especially in later chapters, it's hard to deny he has a point.
Eren yells at Hange for disagreeing with his actions in Libero, pointing out that she and the military refused to come up with an alternate plan, meaning Eren had to go with the original planand attack the city, causing massive civilian losses and getting Paradis to be attacked by the nation of Marley sooner than before. Hange later admits that Eren was right and that their inactivity is to be blamed for the current situation.
In Azumanga Daioh, Yukari calls Nyamo out for getting drunk and telling the girls all about sex while wasted, since Nyamo was trying to keep the beer away from Yukari, but Yukari points out Nyamo is Not So Above It All.
Fukuda is at his most abrasive when he's introduced as Nizuma's assistant, since he belittles Nakai for being unable to get a series of his own started. He's also the only one who isn't completely optimistic about Nizuma's new series Crow's chances, and calls him out on getting complacent. Fukuda, Nizuma, Mashiro and Nakai all brainstorm ways to make Crow better, and Nizuma even apologizes to his editor for ignoring him.
Nanamine, who has a morally dubious plan to rise to the top of Jump, had once sent the main characters fan mail, but stopped when they started writing Tanto, saying they weren't suited to gag manga. This is a bit of an odd case, in that it takes a while for Nanamine to be revealed as a Jerkass, and this opinion was shared by the majority of the characters. He also says that like him, the main characters took risks and defied their editors at times to get what they wanted.
Bakuten Shoot Beyblade: Tyson ripping up Hilary's lesson plan early in Season 2 is portrayed as him being mean and stubborn but he really has every right to be annoyed. Hilary has never even used a beyblade before, yet she's trying to lecture the world champions on how to play. Such a Know-Nothing Know-It-All would get under anyone's skin.
Black Clover: Finral's brother Langris gets a moment like this, despite largely being presented as an unlikable Jerkass. When Finral declares his intent to reclaim his role as the heir of their house and marry Finnes, Langris calls him out his Casanova Wannabe behavior despite saying he will marry Finnes. He's completely right, with Finral actually taking the criticism to heart and trying to correct his behavior from that point on.
In the concept pilot, Orihime's father tells her she shouldn't confess her feelings to Ichigo after her death, because it'll leave him in even more pain. It's a valid point, even if it soon turns out that his time as a Hollow turned him insane and possessive of Orihime to the point where he killed her himself.
At the beginning of the Arrancar Arc when Ulquiorra reports back to Aizen on his findings in the Human World, Grimmjow points out it's a mistake to let Ichigo live. He's proven to be right, since this ultimately costs Ulquiorra his life.
When Yamamoto claims Mayuri only had to kill 28,000 Rukongai souls to correct the world soul-balance because his division was too incompetent to identify the Quincy threat fast enough to prevent things from getting that bad, Mayuri bluntly tells him it's entirely Yamamoto's fault because Mayuri foresaw the Quincy threat as a result of Uryuu's actions during the Ryoka Invasion. However, Yamamoto dismissed Mayuri's concerns as paranoid, which left the Gotei 13 unprepared for future Quincy attacks.
When questioned about his decision to reject the Quincy arts by a young Uryuu, Ryuuken states that he did so because there is no money in it. Uryuu finds this incredibly callous, but his grandfather points out that Ryuuken has a son to feed and raise and so needs an occupation that can provide for him.
In Bloom Into You, the second of Sayaka's light novels shows the time when she and Touko were first-years working for the student council, and Touko tried to propose that the student council revive the tradition of doing a stage show, only for Kuze, the president at the time, to turn her down. Kuze's rejection was rather harsh, and one could imagine that since he delegated most of the work to his officers, he was motivated by laziness, but he had some good points. He points out that the student council would need support from several of the clubs to get the play off the ground, most importantly getting someone to write a scriptnote Technically, there are several old scripts that could be used, but this is generally viewed as a last resort. Kuze also mentions that since none of the student council members have any experience acting, they'll need someone to teach them, which is a difficult proposition given the school's lack of a drama club (which is why the student council put on the play). Touko realizes that he has a point, and by the time she makes the proposal again after becoming president in the main series, she makes arrangements to fill each need.
Early on in the anime version of Bokurano Kodama, a fairly sociopathic young boy, casually states that he somewhat admires Ushiro, a boy who supposedly killed Waku by accidentally pushing him off of Zearth (in actuality, he died from Zearth draining his life force, and was dead before he hit the water), since it means he already has experience taking life. The others nearby are horrified, but Kodama ends up being vindicated. Not only are there massive civilian casualties in some of their battles, but each time they win, the loser's universe is destroyed.
In Charlotte, during the third episode, the main cast meets Yusa Kurobane, an Idol Singer who occasionally channels the spirit of her dead older sister, Misa. Nao Tomori, Student Council President and head of a group that seeks to find and protect users of special abilities from being captured and experimented on, harshly tells Shou and Kouta, Misa's friends, that Misa is already dead, and that if anything, it's unusual that she was able to come back. Shou is offended, but Kouta agrees with Misa. Misa herself also seems to agree, since at the end of the series, after saying goodbye to her parents, she allows Yuu to steal her and Yusa's powers, resulting in her passing on.
Ichigo is a Clingy Jealous Girl who often lets her feelings for Hiro cloud her judgment, but she often makes good points or reasons:
One of the reasons she pressures Hiro to partner with her is that Zero Two seems like a dangerous person who wants to separate Hiro from the squad. She's not wrong about this, but she is twisting the truth for her own benefit.
Episode 5 also shows that she's right not to trust Zero Two with Hiro's safety. And while it is callous of her to accuse Zero Two of not being human, her accusation that Zero Two doesn't care about other people is hard to argue with.
While her renewed hostility towards Zero Two is greatly fueled by jealousy and selfishness, it's not completely unfounded given that Zero Two almost killed Hiro, followed by her beating up the squad in a rage later on.
Her unwillingness to allow Zero Two to see and speak to Hiro after she was told that she would return to her original team in a day is not one of her best moments; however, she is not completely wrong on her justification that Zero Two was deceiving Hiro all along, something that even Zero Two doesn't argue with her when she brings it up.
Miku's jealousy over Ichigo being leader aside, she makes a valid point in Episode 9 when she calls Ichigo out on her perfectionism and constantly letting her emotions overwhelm her every time even the slightest thing goes wrong, which is the exact opposite of how a leader should act. Ichigo herself can't argue with her.
In the finale of Death Note, Near, who, like L, largely only takes on cases that interest him rather than out of a sense of justice, but hates Kira responds to Light Yagami's Motive Rant by telling him that he's nothing more than a "crazy serial killer." No one in the room besides Light, even those who don't like Near, contest that assertion, and Ide says that while he doesn't like Near, if Near hadn't won, Ide and the rest of the task force would be dead.
In Demon Slayer: Kimetsu no Yaiba, contrary to his other Hashira colleagues who eventually accept Nezuko as a good demon, Sanemi remains firmly unshaken with his beliefs that all demons are evil and must be exterminated; as much of a jerk Sanemi is about it, he nor anyone else really had any solid proof that a demon could ever be good before Nezuko appeared, and as the series develops it is consistently shown Nezuko is an extremely odd case where no character could even tell exactly why she remained good beyond the hypnotic measures Urokodaki placed on her and the extreme bond she has with Tanjiro; the other two good demons: Tamayo and Yushiro are also outliers, Yushiro is the only demon made without Muzans involvement, being a direct creation of Tamayo, and Tamayo became good because Yoriichi broke Muzans curse on her, opening the way for Tamayo to decide her own destiny.
Failed Princesses is about a gyaru named Fujishiro gradually coming to befriend Kurokawa, the plain-looking girl she used to bully, a move that puts Fujishiro at odds with her old friend and fellow bully Miki. In Chapter 28, their mutual friend Maho tells Fujishiro that she should apologize to Miki, but Fujishiro insists that Miki needs to apologize to Kurokawa. In response, Maho gives Fujishiro a "The Reason You Suck" Speech pointing out that Miki only bullied Kurokawa because she was following her example and wanted to please her, due to not knowing that Fujishiro and Kurokawa were friends. She also points out that even if Fujishiro and Kurokawa are really friends, Fujishiro can't assume Kurokawa has forgiven her. Fujishiro is at a loss for words, and inwardly accepts that Maho is right.
In Fate/Zero, Blue-Collar Warlock Waver Velvet submitted an essay to his mage master Kayneth, which espoused the idea that even if a mage doesn't come from some great noble family, they could still equal the mages that do through hard work and discipline. Kayneth berated him in front of the entire class, calling him a talentless and naive child who has no right to compare himself to his born superiors. This enraged Waver so much that he decided to join the Grail War just to prove Kayneth wrong. But years later, Waver acknowledges that Kayneth was right: after decades of work, Waver is still nowhere near as powerful as Kayneth was. Due to the way magic works in the setting, to become a great mage despite not coming from good breeding would be comparable to becoming an Olympic athlete despite having crippling arthritis; no amount of training and discipline is going to let the body generate new organs that it doesn't have. Sure, Kayneth was wrong to cruelly dismiss and humiliate Waver, but Waver's claims really were pretty much gibberish and insecure boasting.
In Fly Me to the Moon, Chitose, the adoptive sister of female lead Tsukasa, despises Tsukasa's husband Nasa for his closeness to her sister and tries to break the two up. While Chitose usually acts rather immature and entitled, she's right about one thing — she's known Tsukasa for much longer than Nasa has. Nasa only met Tsukasa once before their marriage, when she saved his life after he got hit by a truck, and didn't see her again until two years later, when she returned to marry him. As a result, it would seem rather strange to Chitose that Tsukasa would marry a man who didn't really know her. Nasa admits that Chitose has a point, but says he'll prove the strength of the love between him and Tsukasa.
In Food Wars!, KojirouShinomiya is an arrogant Jerkass who expels Megumi during his test for what seemed to be very petty reasons, namely not following his recipe because she improvised to adapt for bad ingredients that she only ended up with because he made sure there wouldn't be enough quality ingredients for everyone in the first place. However, he was making a point that a chef needs to be confident and aggressive because he believes anyone who held back so long that they ended up with poor ingredients has only themselves to blame. One of Megumi's most obvious recurring flaws is a lack of aggression and ability to stand up for herself, which Shinomiya's own backstory shows can lead to failure no matter how good of a chef you are. He's also right when Soma challenges him to a food war and Megumi is made the chef because it's her expulsion the match is riding in that she can't keep relying on Soma to carry her through assignments and needs to learn to stand on her own.
As manipulative and "dirty" as he is by his own admission, Shigure genuinely gives very good advice when it counts. Most notably, he calls Kureno out on continuing to remain by Akito's side and doing anything she wants from him despite his curse breaking, telling him point-blank that all he's done is made her worse as a person as she still thinks she can get away with expecting to be loved by others while giving nothing but abuse and spite in return. Near the end of the series, Kureno acknowledges that Shigure is completely right and blames himself for howAkitoturnedout.
Akito may be a psychotic Yandere, but she occasionally makes good points that the Zodiac members are unable to refute:
When Haru calls her out on her treatment of Rin, especially after she locked her up in the Cat's Room to starve, Akito retorts that he's just as much to blame for choosing to pursue Rin despite full knowledge that Akito herself wouldn't approve and would undoubtedly hurt one of them for it. Haru himself acknowledges that he knew the consequences, but wanted Rin so badly that he didn't care.
When Kureno grows a spine and gives her a Rousing Speech, trying to assure her that it's better to live while moving forward instead of being fixated on the generations-old Sohma curse, Akito responds with a Shut Up, Kirk!, ranting at him for choosing to stay with her even after his curse broke because it contributed to her current mental state and gave her false hope. This is particularly poignant because, as stated above, Shigure made that exact same point to Kureno earlier.
While Hiro can be rather rude towards Tohru, a lot of his putdowns about Tohru's weaknesses (like her being an Extreme Doormat and being too attached to her mother) do have some truth to them, especially when it's made clear that Tohru has several issues that she's hiding beneath her positive exterior.
While Ren is a completely vile women who more or less indirectly caused most of the problems for the Zodiac by abusing Akito to insanity, she brings up several good points about the curse that Akito tries to refute:
Ren notes that the outside world will ultimately prove too attractive an alternative to Akito's presence for the Zodiac, which is especially true for Kyo who is destined to be locked away for his entire life. Given Akito's regular abuse of the members (caused by Ren's manipulation), she isn't too far off.
While Ren's claim that no one would love Akito is rather cruel, she's right in that the Zodiac Bond isn't a genuine source of love. The Zodiac only stay by Akito's side and unconditionally forgive her because the curse compels them to, so they have no other choice. No one outside the bond understands it nor sees what they have as a real, healthy dynamic, and the family only justifies it because it's been part of the Sohma family's legacy for generations. This is proven when Kureno's curse breaks, and he cannot understand why he felt the need to be close to Akito, showing that the Zodiac members' "love" for Akito is forced by the curse and not natural.
Ren is revealed to be the one who convinced Akito to let Tohru stay at Shigure's house, as a part of a bet to show her daughter that the Zodiac would rather bond with a kind-hearted outsider than an abusive head of the family. The Zodiac come to love Tohru as family and heal through her, while straining their bond with Akito and leading the latter to have a breakdown.
Solf J. Kimblee. Jerkass has many points. Played especially straight in Chapter 60 where he lectures Mustang and Hawkeye about the nature of killing, free will, and military duty in the midst of war. Kimblee's words affect them so much, they decide to lose the self-pity, accept responsibility for their acts, and atone by putting into motion a long-term plan to change the leadership of the country from below.
When the Elric brothers confront Scar over his killing of the Nina-Alexander chimera, he says that she would have never returned to normal, and would have lived out her days as a lab rat. The brothers find this difficult to accept, but have to admit that even then, they knew on some level that it would have happened and did nothing.
Edward Elric himself starts out as, to be blunt, an arrogant little shit who has a lot of Character Development on the way, but he's not wrong when he tells Rose that she needs to get up and move on, rather than spending her entire life chasing the futile dream of bringing her boyfriend Back from the Dead.
In Gate, Yao further aggravates Tuka's PTSD by coldly insisting that her father was killed by a fire dragon, causing her to retreat further into her delusions and become convinced that Itami is actually her father. When confronted with this, Yao points out that their initial plan to just avoid the issue and allow her to believe her father was still alive was just as bad, and that Itami's later attempts to enforce her delusions by actually pretending to be her father are doomed to fail and likely drive her even further into insanity. Itami eventually concedes to her point, and sets out to destroy the flame dragon with Tuka and the rest of the group to force her to overcome her father's death.
In the Girls und Panzer prequel manga "Little Army", Miho's friend Emi acts very hostile toward Miho's older sister Maho from their first meeting, causing friction between Miho and Emi. Eventually, Emi reveals the cause of her antipathy toward Maho; Emi's older sister's team went up against Maho's team. While Maho's team was winning, one of its tanks fell into the water, and Emi's sister's team's flag tank went after it, but Maho's tank took the opportunity to shoot at the flag tank and win. Miho is hesitant to believe this, but she asks Maho whether it's true, and is quite upset to hear that it is.
In the main series manga, after the match with Anzio (which waspassed over in the anime), Anchovy, the commander, acts like a Sore Loser, angrily saying she doesn't accept Miho's way of tankery and saying that there is no meaning to tankery unless you strive for victory. Miho fires back with an Armor-Piercing Question that asks if Anchovy believes that her and her team's efforts are meaningless because they lost and says her comrades are most important, but Anchovy replies that the commander's responsibility is to lead the team to victory. Ultimately, it turns out that the only way for Oarai to avert being shut down is to place first in the tournament, something none of Miho's team wants, so it is necessary for Miho to win, although Miho doesn't know that at the time and it's unclear whether Anchovy does.
In HappinessCharge Pretty Cure!, Iona has major trust issues towards Hime, snubbing her and essentially being mean to her, even telling Hime's partner Megumi to not trust her. After so long, Iona reveals why: Hime opened the Axia Box and released the Phantom Empire that is currently ravaging the planet. While Hime claims she didn't mean to harm anyone by her actions, Iona's trust issues are justified as Hime's actions caused many lives to be taken away, including Iona and Hime's families. However, this is eventually softened by the fact that while it's Hime's fault that the Earth is being attacked, it's Iona's fault that her sister was taken, as said sister sacrificed herself to protect Iona, who ventured too close to a battle.
In The Heroic Legend of Arslan, after Lusitanian count Barcacion committed suicide, Etoile/Ester hysterically claimed that they will avenge his death and shouted at Parsian soldiers, saying they will kill the person who did it. One Parsian soldier pointed out that since Barcacion took his own life by jumping off a tower, it would be the ground they would need to kill. It was a cruel thing to say to a grieving person but he is right.
Kai is further vindicated in Chapter 85, when Bocchi learns that she has the opportunity to do a referral application to her high school of choice, which has a greater chance of being accepted but places more emphasis on the interview. This is a problem for Bocchi, since despite her excellent grades, she was too scared to do the interview for Kai's middle school, which was the only reason she couldn't get in (and thus why Kai made her befriend her entire class). Nako, who remembers hearing about Bocchi's middle school interview, says that Bocchi needs to be able to rise to the occasion. Bocchi agrees, then prepares for the interview.
Inuyasha: [Nonchalantly.] She means you better take care of any unfinished business before you go to the other world. Kagome: Inuyasha! Inuyasha: Ah, what? Kagome: Sit boy!
Naraku even gets a moment of this; while Kikyo's death and Inuyasha's 50-year sealing are entirely his fault, he nonetheless makes a valid point when he tells them that they were quick to distrust each other and how easy it was to drive a wedge between them. Their world is one where demons are able to shapeshift into other people's forms and/or possess other people, and despite full knowledge that such things are entirely possible, Inuyasha and Kikyo were fully prepared to believe the worst in one another despite being lovers.
When Fujiwara got her fortune in Chapter 51 that stated she is incredibly kind, Kaguya thought that it was a lie and she was actually pretty selfish. Kaguya's thoughts were proven right when Ishigami revealed he shared Fujiwara's birthday and Fujiwara had a hissy fit about sharing the date.
Kaguya is rather ruthless during the election, including forcing a rival candidate to drop out and trying to bribe Iino, Shirogane's other rival, to do the same, and for the arguably selfish motivation of wanting to continue working with Shirogane on the Student Council. However, she's understandably annoyed when Shirogane almost snatches defeat from the jaws of victory by snapping Iino out of her Heroic BSoD, causing Iino to eloquently debate her points and almost win the election despite having been at an overwhelming disadvantage before. Shirogane ends up apologizing to Kaguya for wasting her hard work.
At her worst, Iino can be a shrewish stickler for the rules. That said, while some of her proposed new rules can be rather extreme (e.g. requiring boys to shave their heads), she has an understandable concern for Shuchi'in's reputation suffering due to its students' misbehavior, not to mention one that she backs up with evidence. She can actually cite the repercussions of its declining reputation, such as community associations being less willing to help the school, and can even prove how her rules might help (if students shave their heads, they won't waste time with their hair in the mornings and will be more likely to come in on time). While Shirogane has good counterarguments prepared, Iino's case is convincing enough that she almost wins the election.
Done with Tomoe frequently from Kamisama Kiss. The guy's default personality is sarcastic asshole and the people he likes are not exempt from that sarcasm or his general dickish behavior. That being said, he regularly gives the heroine Nanami sound advice. Too bad she never really listens.
Kazuma from Konosuba regularly criticizes and berates his fellow party members, however given how useless and ineffective they can be he's not wrong. Especially when it comes to Aqua, who despite being a goddess and more powerful than anyone around, does little to try and improve their situation beyond casting healing spells.
In Kotoura-san, Hiyori points out that Haruka's telepathy is an incredible invasion of privacy. Does this excuse in any way, shape, or form, the way she and others treat her for most of the story? Not really... but it's still a valid point. On the other hand, Haruka is unable to turn off her mind reading power, and so has no choice but to read others' minds — her main problem is being unable to keep that ability, and some of her findings, secret.
Oberstein of Legend of Galactic Heroes is a magnificent example of this trope. There is practically no one in the show who likes the guy, and yet he always makes arguments that, although devoid of concepts such as honor and often morals, are simply correct and most effective when looked at logically. Even Reinhard states that he has not once liked Oberstein as a person, but followed his advice the most because "that man makes arguments that are so right, they leave no room for debate".
Smug Snake Job Trunicht is one of the few members of the Free Planets Alliance ruling council who opposes a Free Planets Alliance invasion of The Empire after Yang captures one of the two invasion corridors. Yang, watching the meeting, lampshades that Trunicht's motivation is entirely selfish (if the invasion goes badly, he'll be the main fall guy as he's Secretary of Defense) but his argument (the FPA's economy and supply situation are already about to collapse, making an offensive war unaffordable) is entirely correct.
Little Witch Academia (2017) has an In-Universe example in which Akko considers Diana to be a massive jerk because of her constant criticism. Thing is, almost all of said criticism (that Akko is nowhere as skilled as she thinks she is, believes that she can be a great witch simply by virtue of wanting it really bad without putting forth much effort, and has little respect for the traditions or rules of the institution she wants so badly to be a part of) are all completely accurate. Part of Akko's Character Development is recognizing that maybe Diana wasn't just being mean and actually had a valid point.
Kanako gained quite a bit of popularity with the fans when she calls everyone in Hinata Inn (particularly Naru) on their appalling treatment of Keitaro and even gives Naru a Megaton Punch as payback for all the times she beat up her brother, with Naru even remarking on how she didn't expect it to be so painful. Granted, Kanako is a Clingy Jealous Girl who is in love with her stepbrother who doesn't reciprocate her feelings and some of her wrath is misplaced (such as attacking Shinobu and Su, the former having never attacked Keitaro and Su genuinely doesn't mean to cause Keitaro harm), but her point still stands.
Motoko's older sister Tsuruko is a Yamato Nadeshiko with an unhinged side and her Curb-Stomp Battle against Motoko was decidedly cruel...but she's actually right when she tells Motoko her swordsmanship has deteriorated since she started living at Hinata Inn and calls her unfit to be the successor to their dojo. This prompts Motoko to undergo some serious training and she ends up mastering the demon-splitter move — something even Tsuruko has never managed to do.
Medaka Box: Right after being defeated, Kumagawa makes an point about Medaka's decision to make Kumagawa her Vice-President remarking that she's ignoring Zenkichi's feelings. Personal feelings aside, Kumagawa was nonetheless a dangerous minus who blinded Zenkichi, so distrust of Kumagawa was still partially justified.
Naze calls out the rest of the student council for their bystander attitude after Medaka beats Zenkichi into a bloody pulp.
Kumagawa does it again in Chapter 174. While erasing Zenkichi from existence was quite extreme, it manages to force Shiranui to admit her true feelings rather than continuing her facade.
Tohru's father from Miss Kobayashi's Dragon Maid may have been arrogant and overbearing, but he had a point in warning Tohru and Kobayashi that the former's presence risked causing the war ravaging the Other World to spill over into Earth — as happened when Elma, Ilulu, and Clemene crossed over looking to pick fights.
In Mobile Suit Zeta Gundam the only character to consistently call Kamille out on his Moral Myopia is archenemy Jerid Messa. While Jerid is an arrogant Jerk Jock with a history of war crimes under his belt, he's not wrong when he laughs in Kamille's face over his insistence that all the enemy soldiers are murderers, given that at this point Kamille has killed as many of their comrades as they've killed his.
Daranimaru Goryo, a rather arrogant and ruthless magical law practitioner, says that while Muhyo is superior to him, Goryo's partnership with Ebisu outperforms Muhyo and Roji as a duo. Roji becomes painfully aware that he's The Load to Muhyo, although he doesn't figure out how to fix that until the arc after Goryo's introduction.
Roji ends up being given leave from his position as Muhyo's assistant to learn an important lesson about what it is he needs to do. The one who convinces him that rather than worry about his own capabilities, which would leave him useless to Muhyo, he should do what he can to support Muhyo, is Ebisu, Goryo'sunpleasant and amoral (but also at times sympathetic) sidekick, who does so after telling him his criminal past and loyalty to the Goryo group for taking him in, which allowed him to ultimately accept being fired for his mistake. Roji gets the point, which helps him and Muhyo patch things up.
Goryo himself later reveals that Ivy's parents were not innocent victims, but rejected an offer of lenience and killed magical law officers while resisting arrest. Surprisingly enough, though, at the end of his fight with Ivy, he has a few Pet the Dog moments.
While he's typically the hero, Muhyo sends the spirit of Fujiwara to the equivalent of purgatory, saying that his loss against a rain dog was proof of "ineptitude or negligence, neither of which earns (Muhyo's) sympathy". Roji, despite being typically idealistic and kind-hearted, doesn't question this decision, but does question why Muhyo is performing so many sentencings and using up his tempering even before facing Sophie.
Misato and Shinji's argument after the fight with the Fourth Angel Shamshel. Misato rants at him for ignoring orders and nearly getting himself killed in a horribly reckless stunt that only worked because he got lucky. She's a major hypocrite about this because Shinji had to be blackmailed into piloting, but she's not wrong. Shinji's sullen resentment doesn't change that.
Asuka's grudge against Shinji basically boils down to envy. He's effortlessly better than her as a pilot when it comes to sync ratios. And she's really bitter about him getting a job she worked her whole life to get, because his father said so. There's a lot of other circumstances involved neither of them know about, but she's also not wrong on either account.
Tsubame "Naru" Narumi, a new hire at Eagle Jump, is initially hostile toward Nene Sakura, accusing Nene of not taking her job seriously and claiming that she only got in because of a special favor. Nene admits to herself that Naru wasn't wrong, since Umiko had hired her based on her previous time working for Eagle Jump, even though Umiko outright said that Nene wasn't yet skilled enough for the job. Naru's bitterness toward Nene also becomes more understandable when it turns out that because Naru's parents don't approve of her becoming a game designer, she's had to pay her own way toward college and was told that she'd have to come home and inherit their inn if she didn't get hired at Eagle Jump.
Similarly, Naru also expresses concern about proposed changes to her minigames potentially putting them at risk of missing the deadline, and asking who would be held responsible in that were to happen. She points out that unlike Hajime, who's been with the company for a few years and can afford to make mistakes, she's still in her trial period and needs to prove herself. While this attitude is somewhat selfish, Hajime realizes that Naru isn't wrong to be concerned about how any delays might impact her chances of working for Eagle Jump and apologizes.
Bishamon in Noragami angrily calls out Yato on his case of Poor Communication Kills regarding Yato's father that has led to so much grief when it could have been avoided. She herself experienced all the problems poor communication can cause. She was also brutal in telling Yato that he has some nerve showing his face to Ebisu if he is secretly contacting his father, after what had happened between Ebisu and his father.
In One Piece, after Kaku is revealed as a Cipher Pol 9 spy, Zoro asks him if the fact that he is not a real shipwright means that his assessment that the Going Merry was unable to reach the next island was incorrect, but Kaku says that he was telling the truth back then. Later on, when he goes to the place where Franky and Usopp are going to the ship, he chides Usopp for keeping Merry around, before dumping it into the stormy ocean. Kaku is correct, and the Merry falls apart after saving the Straw Hats from Enies Lobby.
Hody Jones states the painful and obvious truth when giving Princess Shirahoshi "The Reason You Suck" Speech. While yes, it was admirable that she kept quiet about who her mother's killer was and wanted to "prevent the cycle of hatred" from continuing, but by not telling anyone said person grew only worse in their murderous, racist ways before they would eventually initiate a bloody coup d'etat on the kingdom.
In a similar way to Hody, Crocodile tells Luffy that he finds Vivi's idealism impractical, suggesting that the idea of ending Alabasta's civil war without anyone having to die is naive. Luffy, who'd previously punched Vivi during an argument about that subject, agrees, but points out that as she's willing to risk her own life to stop his Evil Plan, he'll fight so she doesn't have to.
Zoro, while not a complete Jerkass, tends to be one of the more abrasive members of the crew when giving advice. However, his advice tends to be right.
During the Davy Back Fight, when Foxy takes Chopper after winning the first round as a result of cheating, Chopper breaks down in tears and laments what happened. Zoro angrily tells Chopper to own up to his decision to join the Straw Hats and that he shouldn't be blaming others for it. Notably, Zoro and Sanji are facing a 3-on-3 match next round, and Chopper was one of the people who was set to participate, so he's facing an uphill battle and doesn't complain about it.
When Usopp wanted to rejoin the crew, he tells Luffy that unless Usopp apologizes, he'd simply be allowing a crew member to disrespect him. Even Sanji, who frequently butts heads with Zoro, tells Nami that Zoro's completely right when she objects.
He is apathetic about Sanji leaving the crew for an Arranged Marriage with one of Big Mom's daughters (although some of the crew suggest that he does care more than he lets on) because the Straw Hats cannot be involved with an Emperor's business when they are at the moment focused with dealing with another Emperor. This is proven right by the time of the Wano Arc. Big Mom pursues the Straw Hats in revenge, and after a series of events ends up teaming up with Kaido, so now the Straw Hats and their allies have two Emperors to deal with.
During Koala's time with the Sun Pirates, Arlong states that even if they bring her home and she tells everyone how good they were to her, her parents and village will still hate fishmen. He was right.
In One-Punch Man the hero known as Sweet Mask is notable for being extremely concerned about the reputation of A and S-class Heroes, showing very little sympathy for the ones who got put in the hospital by the Deep Sea King right before he states this. He's completely right about the reputations, as A and S-class Heroes have an enormous mediatic exposure that makes them important role models and a good reason to not despair even in the presence of the worst monsters-and his point is apparently shared by Saitama, who, after easily taking out the Deep Sea King, claims he could do so only because the other heroes weakened him first and the monster was pretty much running on fumes so the public would continue respect them, and silently proven by Watchdog Man, that live in a city whose inhabitants fear no monster attack because they know any monster attack will be swiftly dealt with and adore him for this. That and the Hero Association, humanity's main and last line of defense against monster attacks, is a non-profit organization that depends on donations from the people to work, and if the people lose faith in their highest-ranked heroes then said donations would dry up and leave humanity defenseless.
The ugly Skeptic from the Deep Sea King arc also comes to mind. After Saitama defeats the literal Monster of the Week, the skeptic starts talking trash about the other heroes and how utterly ineffective they were and how average joes shouldn't be considered heroes. He's completely correct, if an asshole about it.
In Puella Magi Madoka Magica, during a previous timeline, Sayaka is quite hostile to Homura, complaining about, among other things, her tendency to use explosives in combat, since she's worried Homura might blow her up by mistake. Mami agrees with Sayaka on that point, and Homura decides to expand her arsenal by acquiring some firearms.
In Puella Magi Oriko Magica, Homura's deciding to only focus on protecting Madokawhen Oriko and witch-Kirika attack their middle school for the express purpose of killing Madoka, earns Homura a What the Hell, Hero? from Madoka herself that tells her that if she feels that way, she shouldn't try to save anyone. Homura responds that she can't save everyone in this case, and should be at least able to protect Madoka; Mami makes a similar point about not being able to save everyone in the school in an internal monologue. Unfortunately, one of the people they're unable to save is Madoka herself.
The Quintessential Quintuplets: Among the titular quintuplets, Nino is the one who is the most antagonistic towards Fuutarou and not only refuses to study but outright tries to sabotage his sessions. Her main reason for her behavior is that she views him as an "intruder" in their home that could disrupt the relationship between her and her sisters. Said concerns are actually proven true later when the quints (Nino herself included) start to fall in love with him and thus become rivals amongst each other.
Most characters in Rent-A-Girlfriend tend to be a Jerk with a Heart of Gold at best, and a Jerkass at worst, so they're usually rather harsh when they make criticisms of others, including when they're right. In fact, since the people being criticized are no less flawed themselves (especially Kazuya), they generally deserve to be called out.
At the start of the series, Kazuya hires Chizuru as a rental girlfriend while on the rebound from Mami, and has a good time until he learns from Chizuru's past clients that she's only going through the motions while on a date. Furious, then gives her a one-star review (ruining her perfect streak) and hires her again just to rant at her. Chizuru pulls him aside, drops her facade in favor of her true colors and rants at him, saying that he should have realized that her facade is what he signed up for when he hired her. Kazuya comes to realize that she was right, and tries to make up for his previous behavior by giving her a five-star review.
Chizuru also repeatedly calls out Kazuya for his self-pitying behavior and being an Extreme Doormat. Kazuya realizes that she isn't wrong about this, and tries to become a better person.
Ruka can be incredibly clingy, aggressive and even manipulative in her efforts to win over Kazuya, even if it means trying to come between him and Chizuru. That said, she's right that Kazuya and Chizuru's fake relationship is dysfunctional, especially since it involves them lying to their families and friends. She does have an ulterior motive in wanting to become Kazuya's girlfriend instead, but she's not wrong that having an actual girlfriend would be better than having a fake one. In fact, Kazuya starts considering coming clean to everyone, although by the time he does, Chizuru changes her mind and insists on keeping up the lie, at least as long as her grandmother is alive.
Shimizu comes off as rather stern and intimidating, but his assessments about Kazuya's proposal for a film project have merit. He says that the project is doomed to fail unless Kazuya puts in his best effort, and that he needs to consider the perspectives of those whom he's asking for money, asking if Kazuya would pay 10,000 yen (roughly $100) to support an unfamiliar actress. Kazuya leaves the meeting feeling drained, but acknowledging that Shimizu was absolutely right.
During the trip to the beach early on in the series, Kazuya announces that he and Chizuru are contemplating breaking up, partly in order to come clean, and partly out of the vain hope of getting back together with Mami. Kibe punches Kazuya in the face, starting a fistfight between the two friends, and delivers a "The Reason You Suck" Speech calling Kazuya out on treating Chizuru poorly and calling Mami out on stringing Kazuya along. Kibe doesn't know about Chizuru's status as a rental girlfriend, but he's not wrong about this, and Kazuya knows it.
Revolutionary Girl Utena: The resident JerkassButt Monkeys Saionji and Nanami start making good points and recognising how they all are being manipulated towards the end of the series, but by then, each are teetering on the brink of insanity, so no-one listens to them.
In The Royal Tutor, the oldest prince Eines was harsh and blunt about his assessment of his younger brothers but he, just like their father, was correct. Kai is too timid to hold a conversation with people other than their family. Bruno is too strict and inflexible with himself and others. Leonhard hates studying and is a little too simplistic in his thinking. Licht would rather have fun and amuse himself. None of the younger princes made any effort to improve themselves with previous tutors until very recently. Despite the younger princes desiring to aim for kingship, Eines quickly pointed out that he already has several officials and military figures backing him as the successor, having met all the expectations and standards, while the young princes have very little to no support on the matter.
Rumiko Takahashi Anthology: In "The Tragedy of P", Mrs. Kakei is presented as an antagonist for being a cold-hearted woman who obsessively cracks down on the apartment complex's anti-pet policy. However, while she may be harsh about it, it is acknowledged that the policies have already been established from the start, and the tenants who insist on keeping pets despite the rules are the ones at fault for breaking their lease agreement.
Anti-Hero Saitou is generally placed in this role. Though Kenshin's non-killing philosophy prevails in most instances, Saitou points out that Kenshin's philosophy often gives him more challenges and grief against opponents who do not share it. He also coldly points out that Sano's skills would be of little use in a match in Kyoto, and proves it in a fistfight. Sano actually heeded the lesson and Took a Level in Badass en route to Kyoto.
Similarly, Magdaria and Shouzo were doing a great job of not provoking the police, who had stopped them for no reason other than they were Christians... when Sanosuke jumped out from behind a bush and beat the crap out of them and probably got mistaken for a Christian (after all, who else would have bothered?). This is the kind of thing that Real Life activists from oppressed minority groups avoid unless they want to deepen the impression that they're a bunch of dangerous lunatics, so even if Magdaria could have been a little less harsh, she had a very good reason to not be happy.
Rei/Sailor Mars may be a bitch and an unsympathetic bully towards Usagi, but sometimes, she is angry out of frustration for having to deal with somebody as irresponsible and lazy as Usagi, as Usagi at first does not take her Sailor Soldier duties seriously. This is pointed out when Makoto once gets angry at Rei and accuses her of wanting Usagi to be hurt, but Rei tells her that she's just as worried as Makoto and the other girls are.
Shingo often acts like a rude and snarky Annoying Younger Sibling to Usagi, but unlike many other examples, it goes beyond a need to get a rise out of his sister. He's a lot like Rei: he loves Usagi but is annoyed with how lazy and irresponsible she can be. Even their normally compassionate mother can't deny that Shingo is right a lot of the time in his remarks.
While Chibiusa was genuinely extremely bratty and rude towards Usagi, it's somewhat understandable that she would resent Usagi's immature and irresponsible behavior; especially since Chibiusa idolizes the infinitely more wise and graceful Usagi of the future to the point of hurting her own self-esteem.
At the end of Sailor Moon S, Haruka and Michiru angrily call out Usagi on her handling of Pharoah 90. They say that while it is true the world was saved, Usagi acted rashly due to her idealism of wanting to save everyone, pointing out that it's selfish. Because of it, Usagi nearly doomed the whole world. Haruka and Michiru also point out that it was only dumb luck that things worked out in the end since Usagi had no idea how things would've went. They drive it further home saying someone with such flawed idealism has no right to be named a future ruler as they view that kind of person as irresponsible.
While Madoka isn't usually a Jerkass, he loses his temper with Hiraoka when the freelance animators Hiraoka hired do a substandard job, resulting in a heated argument over Hiraoka's attitude and work ethic that escalates into a physical fight between the two men. However, he isn't wrong to call out Hiraoka for his bad attitude, something that several other characters have done. Marukawa tells Hiraoka that Madoka's words got to him as badly as he did because Hiraoka knew he had a point.
Hiraoka himself is ill-tempered, prone to cutting corners, cynical and borderline misogynistic, but he has a somewhat understandable reason to not be thrilled about the direction MusAni is taking on the anime adaptation of Third Aerial Girls Squadron. One of his previous employers did a poor job on an adaptation of another work that the other creator made, and Hiraoka sees some parallels between his current and previous employers.
In A Silent Voice, after the Drama Bomb and suffering a breakdown, Ishida harshly calls out his friends. While he delivered it to a brutal fashion, he was correct. Ueno doesn't believe she did anything wrong in regards to bullying Shouko. Sahara doesn't stand up for herself or others when put in a difficult situation. Kawai is the worst as she refuses to acknowledge she had any part in bullying Shouko. Nagatsuka clings to Ishida because he was nice to him.
Silver Spoon: Hachiken's father has several. For example, expecting someone, even your parents, to fund your start up when your business plan consists solely of cheerful optimism isn't going to happen, and piling on more and more activities when you've already overworked yourself into the hospital once (the circumstances were extreme, but still) is not a good idea.
Knuckles has a massive chip on his shoulder regarding Sonic and often blames him for a lot of things, but he does have a leg to stand on since Sonic got flashy while facing Eggman and duped his robots into shooting the machine that was containing the Chaos Emeralds, which is what triggered the Chaos Control that left them stranded on Earth in the first place.
He gets another moment during the Egg Moon saga, again regarding Sonic. While Sonic destroying Eggman's Sunshine Balls did turn out to be the right thing to do, considering Eggman caused the eclipse that triggered their need in the first place and was keeping it up so the Egg Moon kept blocking the sun as part of a get-rich-quick scheme, Sonic didn't even bother to tell anyone this before he went about smashing the Mirror Towers, and only did so after fighting both Knuckles and the authorities when they tried to stop him. Knuckles states outright that Sonic should have just told them that before he started knocking the towers down.
In Sword Art Online, during the Mother's Rosario arc, Asuna's mother, Kyouko Yuuki, is trying to make her transfer out of the Sword Art Online Survivors' School, as well as accept an Arranged Marriage (or failing that, marry someone who isn't from her current school- i.e. Kirito). Kyouko describes the SAO Survivors' School as little more than a correctional facility, since its lenient terms for admission seem too good to be true, and serve to let the government monitor the survivors for potentially antisocial behavior. Her point echoes one that Kirito made while talking to Suguha back in the Alfheim arc, and Asuna can't articulate a rebuttal to it, although she likes the school well enough to not want to leave.
In the same arc, Kyouko also pulls the plug on Asuna's Amusphere when she's late for dinner and threatens to confiscate it if she's late again. It's a harsh move, especially since Asuna points out that Kyouko could have just shaken her gently and she'd have logged off, but VR addiction is a problem, and Asuna nearly died in SAO, so Kyouko is understandably concerned about Asuna's involvement in another, albeit less lethal, VRMMO. It also overlaps with Hypocrite Has a Point, since it's mentioned in the light novel that Kyouko frequently spends evenings at her office at the university where she works as a professor, resulting in her housekeeper's cooking going to waste.
Mock Sullivan is a rather rude individual who doesn't think much of Lag's dedication to going beyond the call of duty. In one of his first scenes, he refuses a girl named Nelli's request to have him deliver her dead brother Nello's letter to Jiggy Pepper, simply because the letter doesn't have a stamp(something that's prohibitively expensive in Amberground). While that isn't a very nice thing to do, he's well within his rights as a postman to not deliver mail with insufficient postage. Nelli eventually gets the hint, and decides to work to save up enough money for the postage.
"Roda," who's Noir/amnesiac Gauche's dingo gives a brutal "The Reason You Suck" Speech to Niche the first time they meet, calling out Niche for drinking the "honey water" near the town of the same name, and describing Niche as a "failure" of a dingo. Because Niche did that, she became paralyzed during a fight, resulting in Connor being captured by Sarah and Hunt's followers, with Lag barely escaping, and Niche being unable to help during the later fight with the Cidre Gaichuu. Niche takes the speech to heart, and briefly quits as Lag's dingo.
When Zazie's parents come to pick him up from the orphanage, having paid off their debt and not having to worry about him, being taken as collateral, Zazie refuses to recognize them as his parents, having developed trust issues. The cruel, two-faced orphan matron askshim, "If they're not your parents, why would they want a brat like you?" (Ironically, she is the main cause of Zazie's trust issues). Zazie realizes as his parents are leaving that they "made no excuses and told no lies" when challenged, but a Gaichuu eats their hearts before Zazie can talk with them again.
In Tengen Toppa Gurren Lagann, seven years after the protagonists' victory over Lordgenome and his Beastmen, they are faced with the threat of the Anti-Spirals. In response to the threat, Rossiu takes some rather extreme measures, such as using Simon as a scapegoat for collateral damage and having him sentenced to death, having his own lover wired with explosives to keep Simon in line during a battle, and planning to only save part of humanity while leaving everyone else behind to be killed. His methods are morally questionable, and his results aren't always what he hoped for, but he's right about leaders having to make the tough calls for the sake of humanity. When Kittan, one of his harshest critics, plans to Take a Third Option by destroying the moon before it crashes into the planet, Rossiu states that if the plan fails, humanity will go extinct, and asks Kittan if he's willing to take responsibility for that outcome. Kittan grudgingly concedes that Rossiu is right about what it means to be a leader, but says he still doesn't like what Rossiu is doing.
In Wanna Be the Strongest in the World!, local Jerkass Rio Kazama, who is quite infamous for injuring an Idol and putting the main character on a "Shame Hold" just for kicks, has a point when she berates the former for saying Pro Wrestling is easy, which is further proven when the main character, who is inexperienced in Pro Wrestling, gets utterly defeated for 3 episodes in a row.
Weiß Kreuz: Reiji Takatori is the Big Bad of the TV series, and antagonizes Weiss and their boss Persia aka his brother Shuiichi. However, in a certain confrontation, he brings up a pretty valid point in regards to their subordinates (which in Reiji's case, are his own sonsHirofumi and Masafumi), summed up as this: "You tell me I use my sons to my advantage?! Look at the way you treat your four subordinates, you hypocrite! Especially the little guy whom you thought he was my kid... and who happens to be your illegitimate son!" Then he kills Persia.
Mitsuki Yano comes off as a girl who's blunt and overly serious, resulting in most people disliking her during her childhood. However, when she notices that her Only Friend Hime Shiraki lies to her classmates and puts on a cute façade to be popular, Mitsuki tells Hime that she shouldn't try to get close to those people. Some time later, after Mitsuki believes Hime betrayed her by quitting the recital they were going to perform in together, exposes Hime as a liar, and Hime's friends promptly desert her. Years later, Hime realizes that she shouldn't have relied on lies.
Kanoko Mamiya is rather jealous of Mitsuki, to the point of slapping her after Mitsuki claims to be just as special to Hime as Kanoko is. However, Kanoko has a legitiate point when she says it was wrong of Mitsuki to make a Love Confession to Hime without considering how Hime would take it (keep in mind that Kanoko refrained from confessing to Hime), something that Mitsuki herself admits is true.
In Zatch Bell! Brago has just burned the book of a mamodo Zatch befriended. Zatch, angry asks what right Brago had to do that. Brago then proceeds to remind Zatch that the very battle Zatch too is part of requires the destruction of mamodo books to decide a victor. Brago may be a jackass at this point of the series rather than short tempered and violent, but he was definitely within his rights as a contestant.
