* CompleteMonster: Clarence Darby rapes Clyde Shelton's wife, murders her, [[BatterUp savagely beats Clyde with a baseball bat]], and then [[WouldHurtAChild murders Clyde's young daughter]]. They don't even show the audience that scene; it's so horrible. He just takes her into the next room. The line "Don't worry...kids like me." could hint that he raped the girl too. He also attempts to murder Clyde. He proceeds to lie, saying that his partner did it (when, in fact, the partner had tried to talk him out of it), and subsequently laughed his head off when he hears about his partner's agonizing death.
* CriticalDissonance: [[http://www.rottentomatoes.com/m/law_abiding_citizen/ Compare the critical and audience scores on Rotten Tomatoes.]]
* DarknessInducedAudienceApathy: This feeling hits home for viewers who become increasingly disillusioned with Clyde's actions halfway through the film. Clyde starts off as sympathetic, but he eventually becomes worse than the madman (Darby) who sparked off his rage in the first place. As for the attorneys and lawyers on the other side, they're [[StrawmanPolitical immoral strawmen made to look as corrupt as possible]], except for Cindy, [[spoiler: who dies thanks to Clyde]]. When one realizes Clyde's hypocrisy reaches the level of [[{{Film/Saw}} Jigsaw]] it's impossible to root for anybody. See BlackAndGrayMorality.
** Also, Nick's response to his partner asking about Clyde's civil rights? "''Fuck'' his civil rights." It's supposed to come off as awesome, but that's a ''really'' ''bad'' ideology.
* DracoInLeatherPants: There are quite a few people who present Clyde as a hero fighting a corrupt system, ignoring that many of the people who die at Clyde's hands were simply employees doing their jobs and not actively trying to wrong him. That and he killed his cellmate simply to advance his plot. Clyde might be sympathetic, but the crimes he committed are still wrong.
* FauxSymbolism: The [[spoiler: fires that surround Clyde the last moment we see him in the film before his death.]]
** [[spoiler:When Sarah and the others are blown up outside the prison]], Clyde is shown in priest-like black clothes and white undershirt, fingering his daughter's bracelet which resembles rosary beads.
* HilariousInHindsight: At one point Bray says "spies are a dime a dozen", which was included in the trailer. This unintentionally mirrored a line from ''SupplementalMaterial/TeamFortress2'''s trailer "Meet The Spy", which has the Scout saying "[Spies are] dime-a-dozen back-stabbing scumbags!" The payoff? Well, see ''Law Abiding Engineer''.
* JerkassWoobie: Clyde, he kills a lot of people, but he had his wife and daughter murdered and the main perpetrator got off with a slap on the wrist.
** Ames could also count. Yeah, he was Darby's accomplice, but he only wanted to rob the place, he didn't want to kill anyone. Darby sold him up the river when he tried to stop him. Just before his execution, he says that he regrets ever having been there that night. The fact he died a horrible death is pretty sad.
* MagnificentBastard: Clyde Shelton. You may not approve of the idea that guides him, but you have to admit and admire his style and execution.
* MemeticMutation: [[VideoGame/TeamFortress2 The "Law Abiding Engineer" machinima...]] [[NightmareFuel Which works a little]] ''[[NightmareFuel too]]'' [[NightmareFuel well.]] [[http://www.youtube.com/watch?v=HjGrHBpfqCo&feature=related See here]] (unless you happen to be from the wrong country, in which case you can't).
* MoralEventHorizon: Clarence Darby crosses this in the the '''first two minutes''' of the movie.
** Initially, we can sympathize with Clyde Shelton's desire to kill [[AssholeVictim Clarence Darby]] as vengeance for killing his wife and kids. But then there's how he goes about it: paralyzing his body, taking him to his lab and chopping of his limbs with a chainsaw, making a video of this, and sending the video to Nick Rice.
*** Though some would argue that a monster like Darby was simply getting the kind of punishment he deserves. Gruesome fate for a gruesome individual.
*** He definitely crosses it when he murders his cellmate for no other reason then to advance ThePlan. Although there are many different views, this is the most widely cited.
* NightmareFuel: Ames's and Darby's deaths.
* RootingForTheEmpire: {{Deconstructed}}. At the beginning one is hardfelt to not be rooting for Shelton's RoaringRampageOfRevenge against the people that wronged him and the system that deliberately let his killer go just to keep up appearances. But it slowly changes when it becomes clear of how vast Shelton believes the people involved are and is ready to kill a lot of innocent people just to get his revenge.
