Sure it TastesLikeDiabetes. But wait, what's that aftertaste? [[MoodWhiplash Cyanide]]?

Put simply: character behavior which looks or sounds sweet but is just as hurtful and cruel as a direct attack -- perhaps more.

Characters such as MagnificentBastard, DevilInPlainSight, EnfantTerrible, DeliberatelyCuteChild, BitchInSheepsClothing, and some {{Alpha Bitch}}es are all likely to pull off acts of Sugary Malice. A WoundedGazelleGambit is in itself merely malicious, but the fake victim can make it sugary by for example gently "forgiving" the "abuser".

A character who is ObliviouslyEvil, TotalitarianUtilitarian, PrinciplesZealot, WellIntentionedExtremist or similar might also pull off this kind of behaviour -- sometimes without even realizing that his actions are in fact malicious. Such characters might cheerfully murder innocents, figuring that they have a good reason for doing it -- maybe that [[SlidingScaleOfUnavoidableVersusUnforgivable the good outweighs the bad]] or even that [[TooGoodForThisSinfulEarth their victims are better off dead]]. Or they might play BlackComedyRape or RomanticizedAbuse in some misguided belief that it is okay... maybe inspired by a MaritalRapeLicense or a ScaryAmoralReligion. However, in any case, the characters must understand that their actions are abuse or murder or whatever it is they are doing, and still actively choose to do it, otherwise it's ObliviouslyEvil, not SugaryMalice.

[[AC:{{Anime}} and {{Manga}}]]
* In ''Manga/SangatsuNoLion'', Kyoko is telling the stories of Rei's upcoming opponents as if she actually cares. However, her real intent is to lead Rei to his downfall out of her own interests.
* From ''Manga/OniisamaE'', we have [[spoiler: Fukiko]]. Holy CRAP, [[spoiler: Fukiko]]. She is ''incredibly'' good at saying something in the sweetest voice and then ''totally'' turn it around: a great example is how, in the anime, [[spoiler: she invites Aya to the Sorority club house, greets her politely... and then gives her a TheReasonYouSuckSpeech and bans her permanently from there.]]

* In ''Film/GodBlessAmerica'' the big difference between Chloe and Roxy is that Chloe is open about being a jerk, while Roxy is sweet and sort of polite about her utterly depraved psychopathy. Especially when she's trying to sweettalk Frank into murdering people more or less at random.
* In ''Film/NeverLetMeGo'', Ruth has a bit of this, fueled by her fear of being left alone.
** Far worse, however, is the polite kindness that the system shows its victims while pushing them down into despair and death.
* The Camp Chippewah counselors in ''Film/AddamsFamilyValues'' actually seem to enjoy tormenting Wednesday, Pugsley, and the other "weird" kids like this.
** It's extra disturbing given that, from their perspective, their victims are AcceptableTargets. After all, the Addams kids (and the other outcasts) CHOOSE to be weird and not fit the mold of normal! (Yes, that apparently includes people born with funny names, that have a disability, or that are simply ''different ethnicities''. They really should try harder to just fit in with the good, properly white and preppy kids!)
* In the film of ''Film/HarryPotterAndTheOrderOfThePhoenix,'' Umbridge embodies sweetness and gentleness as a thin veneer over a sadistic desire for control -- much like in the book. However, Imelda Staunton's Umbridge is [[AlternativeCharacterInterpretation a slightly different character]] -- in the book, either Harry or the narrator finds Umbridge repulsive from the get-go, while in the film, Umbridge seems significantly more likeable and, well, grandmotherly. She's still terrible, but now more credible as someone who would rise to a high government office.

* In ''Literature/DragonBones'', high king Jakoven, when talking to [[spoiler: Garranon, about the first time they met]] manages to put a facade of pity and affection over a "I know where your family lives" threat. It makes it all even creepier.
* Creator/JamesHSchmitz's Literature/TelzeyAmberdon short story "Novice". Telzey's Aunt Halet cloaked her malicious intent behind a pleasant fašade.
* In ''Literature/{{Harry Potter and the Order of the Phoenix}}'', Dolores Umbridge tortures students -- but she's very polite about it, in a grandmotherly way. And just ''look'' at all those cute little kittens!
* Two short ''Literature/{{Goosebumps}}'' stories veer into this territory. The first, "Please Don't Feed The Bears," is about a girl who gets dragged to a cutesy teddy bear theme park until she realizes that the workers actually are living teddy bears and try to turn her into one as well. The second, "A Holly Jolly Holiday," is about an evil video tape that turns people into the diabetes inducing Christmas-themed heroine Susie Snowflake.
* The ''Literature/JustWilliam'' stories by Richmal Crompton had William's archenemy Hubert Lane who oozed a kind of offensive, oily, condesceding politeness.
* Caroline Bingley in ''Literature/PrideAndPrejudice'' is constantly delivering condescending put-downs and backhanded compliments drenched in a sugary, faux-pleasant tone. She uses it mainly on Jane Bennet, who is too genuinely sweet and naive to pick up on it, but she will also use it on Elizabeth Bennet (whom she otherwise displays less regard for) if the situation means she can't get away with more obvious nastiness. Elizabeth, who is a lot savvier than her sister, isn't fooled for a second.

* ''Series/EverybodyLovesRaymond''. Marie often made insulting comments to Debra while pretending to give friendly advice...though Debra increasingly began employing it as well. [[{{DoubleStandardAbuseFemaleOnMale}} However, when it came to her interactions with Ray, Debra delivered the malice sugar-free. ]]
* In the ''Series/TheManFromUNCLE'' episode "The Gazebo in the Maze Affair", the villain's wife, Edith Partridge, initially appears to be a sweet, if not-entirely-there, old lady who is oblivious to her husband's evil. It soon becomes apparent that she's pulling many of the strings, and she tortures the heroes -- and gives her husband instructions on how to torture them "properly" -- without ever changing her sweet manner.
* Anna in the ''Series/{{V 2009}}'' remake is pretty much the poster child for this. So sweet and innocent. And of course she is of peace, always. Even when she incites civil unrest, has people tortured to death and generally plots the destruction of mankind. ''Especially'' when she does those things.

* ''Theatre/ArsenicAndOldLace'' centers on a certain pair of sweet old ladies who are inviting gentlemen over to drink homemade wine and then poisoning them.

[[AC: VideoGames]]
* In ''VideoGame/TheKingOfFighters XIII'', the best example is [[spoiler: Mature]]. She speaks softly and in a borderline flirty way to her upcoming rivals, and it's almost immediately followed by a very aggressive quip about her wanting to see them bathed in blood after she kills them.

* [[PunnyName Mother]] [[MeaningfulName May-Eye]] from ''WesternAnimation/TeenTitans'', a RealityWarper with a side-order of mind-control, is by far the scariest of all the villains the Titans faced (not that it's an area of great competition).
* Daemon from ''WesternAnimation/ReBoot'', though [[BlueAndOrangeMorality she honestly doesn't see her actions as malicious]].
