Everyone knows it's a bad idea to mess around with evil. If you're foolish enough to poke a concentrated ball of malevolence, you've got no one but yourself to blame for the consequences. Conversely, we should expect goodness to be more, well, user-friendly? Less liable to reduce you to a pile of ashes for looking at it crosswise?
Don't count on it.
Even when Light Is Good, it can still be too hot to handle. Maybe holiness is judgment untempered by mercy, and only the most incorruptible people can come in contact with it and come away unscathed. Maybe it's really temperamental, and objects violently to being used for any but the most noble causes. Maybe it's just that light burns, and enough holiness in one place is naturally dangerous to anyone, not just the wicked. In any event, you'll probably rest easier with some safe distance between yourself and anything really holy.
This may be the logical extreme of White Magic. While Black Magic involves drawing power from others, and has a tendency to kill or corrupt anyone, White Magic generally helps others through self-sacrifice and purges evil. Think about the implications of this: purging evil can range from the depraved villain to the Noble Demon to even an Anti-Hero to anyone even remotely human, because all people are capable of evil. Another way to think about is thus: If you aren't willing to make the sacrifice, you get punished, but if you are worthy enough, you get sacrificed. Likewise, anyone helped by your sacrifice is likely to be saved or punished by its effects.
Closely related to Holy Hand Grenade; the distinction is that this trope refers to holiness being inherently dangerous to Muggles, whereas Holy Hand Grenade is when holiness is weaponized. Also compare and contrast Holy Burns Evil. Sometimes manifests as Cast from Hit Points or Brown Note. See also Humans Are Flawed for a possible reason Holy Is Not Safe. Contrast Revive Kills Zombie, in which something beneficial to normal beings is harmful to unholy and/or undead ones. The Evil Counterpart is Evil Is Not a Toy.
- The Innocence in D.Gray-Man is the Divine Crystal used as a weapon by Exorcists. As such it is obviously harmful to evil beings... but it can just as well be harmful to the good guys. Parasitic type Exorcists (whose weapon is a part of their own body) are stated to have a short life-span due to the sheer amount of energy it consumes. Also, any Exorcist who forgets his mission will be eaten by the Innocence from the inside, and die after turning into an uncontrollable monster that indiscriminately destroys everything around it for several hours. Finally, non-Exorcists cannot stand being exposed to pure Innocence, even if they aren't evil.
- Holy weapons in Miss Kobayashi's Dragon Maid are completely non-judgmental in who they hurt, with Tohru mentioned that the sword that pierced her back would have Mind Raped any mortal who touched it (Kobayashi was only able to remove it because she's an atheist). Also, the one named character shown wielding one was a blatant racist trying to bring about a war.
- In Scrapped Princess, Ginnungagap is the highest known military grade offensive spell, and is so powerful that it must be sanctioned for use, by way of unanimous decision, by the High Council. The attack itself covers a wide area and is devastating enough on its own, but the real threat is resulting shockwave triggered by it. When used, it caused a mega-tsunami that devastated the majority of the continental coast!
- Yu-Gi-Oh! gives us the Egyptian God Cards, the most powerful and dangerous monsters in the game. Only a chosen duelist can summon a God Monster; anyone else who tries (or who uses a counterfeit card) will be struck down. Even when they all end up in Yugi's hands, they're still extremely dangerous, and Yugi resolves to be careful with how he uses them.
- Johnny Storm the Human Torch of the Fantastic Four had the bad luck of being burned by Hellfire and the Flaming Sword of an archangel in the same story arc. The archangel's sword was more painful.
- The Angelus from The Darkness has this trait in spades. She/It represents the light of creation and is the divine embodiment of law and order, but is indiscriminately dangerous to all who get in her/its way of purging the Darkness. The Angelus was known to have destroyed The Tower of Babel, torn down the Walls of Jerusalem, and ripped apart Krakatoa simply as a display of its holiness and ferocity.
- An important plot point in a JLA story where earth was being invaded by a renegade king angel called Asmodel to hunt down the fallen angel Azrael because Azrael knows about Asmodel's plan to rebel and try to take control of heaven. The angelic soldiers and their weapons including their massive flying ship use holy power and Azrael is horrified because he knows that such powers and objects are too much for the mortal world.
Azrael: We're talking about a higher order of reality entering this plane. The world they come from, the world I come from, has...more of everything. I don't think you understand yet; the light of heaven would slash open your corneas. The music of heaven would puncture your eardrums and drive you insane. the air in heaven would burst your lungs and boil your blood. Only spirit can bear heaven's touch.
Asmodel: How!? How can you bear the scouring light of heaven!? Only the purest of souls can gaze upon this flame and not be driven mad!!
- Averted in a Chosen One kind of way with Superman in the very same story arc. Just when Asmodel is about to finish the Martian Manhunter, Superman shows up and tells J'onn to stand down and let him take care of Asmodel. Not only does Superman hold his own and stand toe to toe with Asmodel, but when Asmodel gets desperate and blasts Superman with holy light, Clark completely no sells it. When Asmodel, baffled by this, comments on it he also inadvertently confirms what everyone already knows about Superman.
- Indiana Jones
- As in the scriptures, The Ark of the Covenant in Raiders of the Lost Ark is an inherently dangerous artifact. Indy and Marion aren't killed by it because Indy remembers the Bible saying not to look upon the open Ark. Those Wacky Nazis aren't so lucky.
- In Indiana Jones and the Last Crusade, the artifact is the Holy Grail, which isn't deadly itself, but has some rather deadly traps protecting it. (Seeing as the Grail can't be taken from the temple and the eternal life it bestows only lasts so long as you stay there, one has to wonder why such traps are necessary.) Elsa discovers this the hard way when she attempts to take the grail towards the exit and sets off the self-destruct sequence. In a Take My Hand scenario, she obsessively tries to reach for it, despite hanging over an abyss. She falls to her death and Indy almost does the same, until his father tells him to let it go.
- Dogma uses the idea that God's voice is fatal to mortals as a plot point. It places Metatron (whose purpose it is to relate God's words to mortals) in the role of Mr. Exposition, and is used to destroy the renegade angels.
Metatron: Humans possess neither the aural nor the psychological capacity to withstand the awesome power of God's true voice. Were you to hear it, your mind would cave in and your heart would explode within your chest. We went through five Adams before we figured that one out.
- Played for Laughs with the Holy Hand Grenade of Monty Python and the Holy Grail, which contains long and repetitive instructions about how to safely use it.
- The Young Wizards series likes this trope:
- The Archangel Michael manifesting at full power strains the fabric of reality nearly to the breaking point.
- The True Name of God is so potent that, if not kept in two separate pieces, its raw power would destroy entire universes.
- If more than one of the Four Great Treasures of Ireland is kept in the same house without proper preparations, the result would "make a nuclear bomb look like a wet firecracker". The spirit of the Spear Liun, whose element is fire, is particularly temperamental: it wants to burn the evil, darkness, and entropy out of things, and it hurts to look at because entropy is bound to some degree into every living thing.
- The Book Of Night With Moon, the book (at least as it appears to humans) that defines the operating parameters of the Universe, is described as "blindingly bright" (in a psychic sort of way) and most adult wizards fear the idea of being a conduit for such immense power when someone has to read from it to remind the Universe how to behave.
- The sword Dyrnwyn in The Chronicles of Prydain, the only weapon capable of slaying the undead Cauldron Born and the Dark Lord Arawn, also has a pronounced tendency to kill any unworthy person who tries to wield it.
- In The Dresden Files, Harry receives the Soulfire power from Archangel Uriel, an ostensibly holy ability that is basically the fires of Creation ... which is powered by his own soul. Though according to Bob, this really isn't as big of a deal as Harry thinks it is. The soul is somewhat malleable, and any portion of his soul that he uses up will eventually come back. So long as he doesn't use Soulfire too much in a short amount of time, he'll be fine. If he does, then as Bob put it, "if you subtract five from five..."
- The Silmarillion by J. R. R. Tolkien:
- The Silmarils were gems of light that burned everything and everybody trying to touch them who wasn't Incorruptibly Pure.
- Eru Ilúvatar, the ultimate Creator, left the Valar in charge of the world to guide and help the humans and elves. When the Númenoreans decided to declare war on the Valar and invade their land, however, the Valar were unsure what to do and asked Ilúvatar to momentarily take control of the world once again. He responded by immediately sinking the Númenoreans' whole country into the sea, leaving only three ships of faithful survivors.
- Earlier in the First Age, when the inhabitants of Middle Earth finally managed to get a messenger across the sea to the Valar to say (paraphrased), "Hey, sorry about that dust-up a couple thousand years back, but there are a lot of innocent people over here who had nothing to do with that, and we could REALLY use some help against the God of Evil. Do a brother a solid?" the Valar came over en masse to kick Morgoth out of creation. The resulting battle sank the better part of the continent into the sea. Wanting to avoid a similar catastrophe is a big part of why they adopted a relatively "hands-off" policy during the War of the Ring.
- The Orb of Aldur in The Belgariad will kill anyone who touches it unless they are "pure", which really means "a direct descendant of its last wielder"; purity is In the Blood, apparently. As this line is thought to be extinct, and the danger is well-known, no one has touched the Orb for hundreds of years. The plot of the series kicks off when someone, somehow, manages to steal it.
- The standard of "purity" for safe handling of the Orb is stated to be "without ill intent in the silence of his soul". The original (human) wielder met the standard, as did the thief (a small child who, having been carefully raised to be perfectly innocent, didn't understand the concept of theft, or how it applied to "take the pretty glowing rock and give it to the man who raised me"). Descendants of the original wielder are able to handle it despite having some ill intent because the orb - being sentient - likes them. Testing how much "ill intent" that lets them get away with is a bad idea.
- In VALIS, the narrator notes that Horselover Fat's encounter with God was no better for Fat's sanity than the illegal drugs he used to take. Also, the meeting with God had the side-effect of giving cancer to all Fat's pets. (On the other hand, it's possible that the entity Fat met was not actually God—it's a point that gets debated extensively by the characters, and never completely resolved.)
- Works by C. S. Lewis:
- In The Chronicles of Narnia, Aslan, the local Jesus-stand in, is explicitly described by Mr. Beaver in The Lion, the Witch, and the Wardrobe as "not safe, but good." He doesn't harm anyone arbitrarily, but he may render judgment on people without immediately letting them realize it's a moral lesson, as with Aravis in The Horse and His Boy whom he clawed in punishment for her callously allowing her servant to be beaten.
- In The Silver Chair, when Jill Pole first meets Aslan, she asks him if he eats little girls.
"I have swallowed up girls and boys, women and men, kings and emperors, cities and realms," said the Lion. It didn't say this as if it were boasting, nor as if it were sorry, nor as if it were angry. It just said it.
- Lewis has his literary avatar of J.R.R. Tolkien encounter this in Perelandra, the second book of The Space Trilogy. Lewis barely manages to fight his way past the fright tactics of harassing demons, to reach a friend's house. There, he sees a beam of unearthly light and hears an inhumanly beautiful voice speaking to him, realizes he is in the presence of an angel ... and is even more terrified. Justified, as the first thing any angel says in the Bible when they show up to talk to someone is, "Do not be afraid." He muses that the reason is because when you're confronted by something evil, you can still hope for something good to rescue you. When you run into something good and are still terrified...
- In Dragon Bones, the protagonists make camp in the ruins of an ancient temple. Turns out the temple is haunted by the god himself. Ciarra is possessed by the god, and Oreg suffers horribly because he couldn't protect her. Though the latter is caused by the magic with which Oreg was Made a Slave, the god doesn't seem to have much compassion, either. Needless to say, the main protagonist, Ward, is quite angry at that Jerkass God.
- Angels and demons both have to possess a human in order to walk the Earth. Angels require the consent of the human who is to be their vessel, but just because they're angels doesn't mean it's all going to turn out okay. Many angelic vessels are killed or left broken like victims of bad lobotomies after the angel is finished with them.
- When Pamela calls on Castiel to show himself (she's trying to find out who got Dean Winchester out of hell at the beginning of Season Four), he burns her eyes out because humans can't look upon an angel's true form. Did we mention that their true voices shatter glass, shakes buildings and makes your ears bleed?
- The Archangel Michael does the same thing to some hapless humans who happen to be sitting in the same bar as Zachariah (a middle-management angel). Unlike Castiel, he doesn't seem to regret it.
- In Star Trek: Voyager, the Borg see the Omega molecule as the pinnacle of perfection and seek it with an almost religious reverence. When Seven of Nine observes Omega molecules self-stabilizing in "The Omega Directive", she reacts as if she is having a religious experience. However, Omega molecules are among the most dangerous substance in the universe, capable of generating deadly radiation, creating massive explosions, and destroying the fabric of subspace.
- This is Older Than Feudalism. In Greek Mythology seeing the undisguised glory of a god would strike mortals dead, as happened to Semele, one of Zeus' many human lovers and the mortal mother of Dionysus.
- From The Bible:
- The Book of Exodus provides the page quote. Moses asks to see God's face. God answers that this would kill Moses, but He does arrange for Moses to see His back* instead. Even just His back has the result of Moses' face glowing for several days and having to wear a veil in the meantime.*
- Nadab and Abihu were priests serving the Lord's tabernacle. When they deviated from the established procedure of worship by offering a "strange" fire to God, they were immediately struck dead for their troubles.
- The Ark of the Covenant was far too holy for any ordinary person to come in contact with, hence why the priests carried it with poles. Attempting to touch it, even for a good reason, as in the case of the Israelite Uzzah in 1 Samuel who tried to prevent it from falling on the ground, would result in that person being struck dead instantly. One exception is when the Ark resided in the home of Obed-Edom (right after the death of Uzzah), where the Lord blessed his household for the three months that it stayed there.
At another point in 1 Samuel (Chapters 4-7) the Israelites tried to use it as a good luck charm in battle against the Philistines. Its presence ended up galvanizing the Philistines who ripped the Israelites a new one and captured the Ark. Then the Philistines made the mistake of keeping it in the same room as an idol of Dagon, and God destroyed the statue and struck them with a plague of tumors and rats. The Philistine cities started playing hot potato with the thing and eventually decided to send it back to Israel with a guilt offering. Aaaand the Israelites promptly had a whole bunch of people die from looking into the Ark. Seriously, compared to the Ark of the Covenant nuclear waste is safe.
- Jewish tradition has the archangel Metatronnote whose job is to be the voice of God, employed any time in the Bible when people hear the voice in the sky. Presumably hearing God's voice is just as dangerous as seeing His face.
- Oh hell, even angels aren't safe! The Seraphim are mentioned as using their first pair of wings to cover their faces while they cheer God on.
- Despite warnings from the priests, King Uzziah attempted to burn incense in the temple as a sacrifice to God. God got extremely angry at him for performing a task exclusively reserved for priests and so the king was struck with leprosy.
- In St. Paul's First Epistle to the Corinthians, he warns that Communion is not safe for those lacking reverence and holiness. While it gives life to those who have been prepared to approach the Table of the Lord, for those who are not prepared, it brings curses, illness, and can even kill you.
- In Acts Saul/Paul was on the road to Damascus and then struck blind by a heavenly light.
- The Islamic version of the aforementioned story about Moses asking to see the face of God/Allah has it that after making a similar warning about the dangers involved, Allah told Moses that He would reveal His Face to a nearby mountain (and only that mountain), so as to let Moses witness what could happen. The result? The mountain is instantly reduced to be as even as the land around it. The implication from other Islamic traditions is that all creations of Allah cannot help but completely humble themselves before His fully unveiled glory, and that what happened to the mountain was the equivalent of an extreme Pose of Supplication. As for Moses, he understandably fainted from the spectacle.
- Bhagavadgita has a downplayed version of the theme employed in the three above examples: seeing Krishna's true form, the god Vishnu, does not harm humans (at least, as long as he doesn't mean harm), it just freaks them out real bad.
- In later interpretations of Arthurian legend, the Holy Grail tended to be this. Only Sir Galahad, the purest of knights, could survive looking upon it. This might also be said to apply to the Siege Perilous, Galahad's seat at the Round Table, which marked the knight destined to complete the Grail Quest. Anyone other than Galahad who sat in it would immediately die.
- In Hawaii, lava rocks and black sand are considered sacred; they are considered to be Pele's "babies." Legend has it that taking them from wherever you find them will awaken Pele's Mama Bear tendencies and bring some kind of bad luck. For this reason, many lava rocks end up being mailed back after those who took them as souvenirs attribute to them whatever misfortunes have befallen them.
- In asian mysticism, Yang, the energy of light and Heaven, has to be balanced with Yin, as otherwise your body will be unbalanced and suffer from excess Yang, with things like fever and excessive anger being common symptoms.
- Dungeons & Dragons:
- Positive Energy is a type of magical energy closely associated with life, and spellcasters often channel it when casting healing spells, Holy Hand Grenades, or Turning Undead. The Positive Energy Plane is made entirely of the stuff, and trying to visit it without appropriate protection will cause your body to become overloaded with life energy, which will vaporize you if you spend too long there. Depending on your Constitution, "too long" ranges from a few minutes to literally seconds.
- From the Book of Exalted Deeds 3E sourcebook:
- The Words of Creation, a precursor tongue to Celestial considered inherently good to the extent that no evil creature can speak them or bear their sound. However, most uses of the Words cause the user to suffer varying amounts of nonlethal damage (for example, speaking another creature's true name inflicts 5d4 damage on the speaker).
- The same sourcebook also introduces sanctified spells, which are spells available only to good-aligned spellcasters who prepare spells before casting them. Like the Words of Creation, most are Cast from Hit Points in the form of varying levels of ability damage or, in the case of Exalted Fury, death.
- In Warhammer 40,000, astropaths are psykers who make brief psychic contact with the nearly dead God Emperor of Mankind so they can safely use their psychic power for FTL communication. This has the unpleasant side effect of burning out the astropath's eyes.
- Happens in the fan made Wo D Princess: The Hopeful, where bathing in the Light of the Dreamlands is beneficial, but going any deeper then the shallow end of the pool will obliterate everyone, including the Light's own champions.
- The existence of the Twilight Courts is also an example; all three Courts still serve the Light in their own way, but they're often not the best Nobles to come to the attention of.
- Magic: The Gathering contains many white cards that brings holy destruction everywhere, every block usually containing at least one of these. The most iconic examples being Wrath of God and Day of Judgment, both of which destroy all creatures (including the caster's).
- Final Fantasy VII:
- The White Materia, Holy, is the Planet's ultimate defensive measure. It wipes away anything it judges as a threat to the Planet, which could easily include humanity. Its only thanks to a last-minute intervention by Aerith via the Lifestream that it actually doesn't.
- The various WEAPONS (giant monster creatures, not actual swords/guns/etc.) are the backup in case Holy doesn't work. However, since the Big Bad who's actively trying to destroy the Planet is hiding behind a shield that even the WEAPONS can't penetrate, they opt to go after the #2 threat to the Planet instead. Which would be humanity.
- Hexen II weaponizes holiness with one of the crusader's weapons. It is a beam of holy light that burns even on the most minor of guilt that exists in all living things.
- At the end of Riddle Of The Sphinx, clicking on the light from The Ark of the Covenant knocks your character out temporarily.
- By implication in Aoi Shiro. The <<Sword>> is a holy object but in addition to being the Key to the Lapis Lazuli Gate it has a corrupting influence on humans and oni alike unless they have enough power to fight off the influnce or the right sort of power to neutralise its effects.
- The Elder Scrolls
- The eponymous Elder Scrolls themselves are referred to as "fragments of creation", and are (usually) kept under close guard by the Cult of the Ancestor Moth, a sect of specially trained "Moth Priests" who are the only people typically allowed to access or attempt to read the Scrolls. Despite the divine nature of the Scrolls, mortal readers are typically struck blind and insane following readings. Moth Priests undergo a lifetime of rigorous training which allows them to overcome these side effects, but only for a finite number of readings before they too are struck blind.
- While most of the series Legendary Weapons and other artifacts of great power are associated with the (often amoral) Daedric Princes, the (often more benevolent) Aedric Nine Divines have gifted objects of great power to mortals as well. The Crusaders Relics are prime example - a set of blessed armor and weapons granted to Pelinal Whitestrake, the divine champion of St. Alessia in the 1st Era during her conflict with the Daedra-worshiping Ayleids. Included are a mace and sword enchanted to inflict fire-damage. Pelinal used this equipment to commit near-genocide against the Ayleids. This equipment needs to be recovered and sanctified in Oblivion's Knights of the Nine expansion, where the Player Character is "Pelinal Reborn" and needs to defeat Pelinal's ancient enemy, Umaril the Unfeathered.
- The Zombie Apocalypse that nearly destroys New Tristram in Diablo III is eventually revealed to have been inadvertently caused by the power of Justice: the zombies were the remains of people unjustly killed during previous conflicts between humans and demons, brought back to life because the power of Justice became unregulated after the Archangel of Justice, Tyrael, renounced his position and fell to Sanctuary to take a more active hand on humanity's behalf against the forces of Hell.
- In Planescape: Torment, Trias the Betrayer's has a pair of charred, skeletal wings. The first explaniation you get for this is that they were mutilated by prision guards (which is plausible, since he is currently imprisoned on a plane which is basicly one giant prision. In actual fact his wings were burned to a crisp when he was cast down from the heavens. He claims that all of the fury of the Abyss pales in comparison to the divine wrath that burned his wings off.
- In the Bayonetta series, the Umbra Witches need to make a Deal with the Devil in order to gain their powers. The Lumen Sages, their light-based counterparts, do something similar, making contracts with angels ... however the angels in this universe are anything but benevolent, despising humanity for their weakness. Also, just as Umbra Witches get their souls dragged down to Inferno when they die, the souls of Sages are taken into Paradiso, where its insinuated that their souls are used to create Cannon Fodder soldiers for the angelic armies.
- The Apollo Sanctum in Golden Sun: Dark Dawn is bathed in light so intense that it can incinerate anyone who approaches it unless they're wearing the Umbra gear, which covers the person in darkness. However, the heart of the sanctum (which your party needs to access in order to banish the darkness threatening to consume the world) has the light that's even more intense than normal and not even the Umbra gear can give adequate protection. Volecheck decides to fire the Apollo Lens in your party's place so that he sacrifices himself instead and he gets incinerated by the light.
- The Hallow in Terraria, a spreading biome filled with holy energy that forms colourful trees, and rainbows as opposed to The Corruption and The Crimson. Sounds pleasant? It contains pixies, unicorns, and gastropods that will tear you apart (and in the case of the latter, Beam Spam you) with frightening ease.
- Gaia/Yggdrasil/The Immaculate Machine in The Secret World is a massive divine supercomputer within and without the Hollow Earth, with its Magitek symbiotic bees being the source of all player characters' magical sensitivity. It also has the usual slew of Alien Geometries, unknowable truths and burning white light inflicted upon those with no magical aptitude who happen upon an entrance to Agartha.
- Large parts of the angelic plane of Elysium in Nexus Clash can and will burn anyone who isn't a full-blown angel to death no matter what their ranking on the Karma Meter.
- The Master Sword from The Legend of Zelda has always been a holy sword that Only the Chosen May Wield (or at least remove from its pedestal). Breath of the Wild, however, reveals that to remove it from its pedestal requires a test of strength - it drains the life from whoever grasps its hilt, and if they aren't worthy or aren't stopped from pulling it, then they die. Link has to undergo this test in order to claim the Master Sword, and if he doesn't have enough hearts then the sword will kill him.
- The entrance to the Maze of Many in Goblins is built into the blade of an angel's sword, lost in some long ago cosmic war. The sword is the size of a building, and while the portal is relatively safe to pass through touching the sword itself instantly vaporizes the poor schmuck that did so. Kin has to prevent Minmax from peeing on the sword before they go in.
- In My Little Pony: Friendship Is Magic: Equestria Girls spin-off movies it is shown that the magic coming from the Elements of Harmony — artifacts which are normaly used to banish or purify evil by the heroes — can not only turn people in the human world very powerful, but also monstrous (not just in appearance), crazy, extremist or all at the same time.
- My Little Pony: Equestria Girls: After the already nasty resident Alpha Bitch Sunset Shimmer gains hold of Twilight's Element, it turns her into a demon. She then goes onto brainwash the whole student body into an army of zombies and then tries to outright kill the protagonists with a fireball.
- My Little Pony: Equestria Girls Friendship Games: When the socially awkward Human Twilight is coaxed into unleashing all of the magic her pendant has absorbed up to that point, it corrupts her and she very nearly ends up destroying reality in her attempt to try to gain access to more knowledge about magic.
- My Little Pony: Equestria Girls Legend of Everfree: A workaholic Gloriosa Daisy is under heavy stress from the threat of losing her family's camp and tries to make everyone's time there as best as she can with the help of the magic coming from the Equestrian geodes. It eventually corrupts her and she tries to trap the campers to the point of nearly harming them, while claiming she's trying to preserve Camp Everfree for them.
