Light Is Not Good/Live-Action TV

""What about hope, charity and mercy?"
 * Buffy the Vampire Slayer gives us The Initiative. They're a government agency with sleek, white labs that captures and experiments on supernatural creatures, likely to make the US more powerful.
 * One of the titles Glory's minions call her is "The Shining Light".
 * How about Light from the Doctor Who story "Ghost Light"? Wants.
 * Weeping Angels? Angelic statues which kill you by teleporting you into the past and feeding off of potential abstract energy.
 * As well as the Time Lords, Depending on the Writer.
 * The Doctor even more so. Half the time he's being portrayed as Jesus, half the time he's committing highly dubious acts without actually realizing he's doing something wrong.
 * It really depends on the doctor. 10 starts off as a rather goofy, nice guy, but ends up as one of the most morally questionable characters in the series, leaving the universe to be saved by The Master! 9 ends up being pretty nice and rather human, whereas 11 does some things that are morally grey (such as lying to future!Amy and eventually ending her life to save normal Amy) but always seems genuinely sorry afterwords.
 * In Midnight, the light is literally killer.
 * The new Daleks, with their bright and shiny paintjobs. Still total bastards.
 * Trent Fernandez from Power Rangers Dino Thunder before his Heel Face Turn
 * Then there is The Evil White Ranger Clone
 * The Alliance in Firefly puts on a pretty face, makes everyone believe that what they are doing is for the greater good of all mankind, when in reality they're drugging entire planetary populations into starving themselves to death for "peace" (though this was unintentional), dispatching agents authorized to kill entire settlements of noncombatants to cover up embarrassing secrets and cutting up the brains of children to turn them into psychic assassins.
 * This is touched on in Carnivale, as there seems to be no moral dimension for being the Creature of Light or the Creature of Darkness; the latter just seems to spread calamity around himself whether he wants to or not. The current Creature of Light is a decent, albeit extremely reluctant guy, but his predecessor is ruthless, manipulative and cruel. Interestingly, he's not beautiful in the slightest, despite being associated with Light, and prefers to hide behind a curtain or make himself invisible to keep the shroud of mystery around himself.
 * Samson also mentions it in his pilot monologue: "...A false sun explodes over Trinity..." This is a reference to the Trinity Test of the first atomic bomb (a perfect Real Life example of this trope).
 * Babylon 5 has Vorlons, who  and seem to be helping the younger species fight off the evil Shadows. However, it turns out that the conflict is not between good and evil, but between stasis and chaos. Neither extreme is beneficial for the younger species, who are exploited as pawns in a deadly game. Ultimately,
 * The antagonist in the Farscape episode "Crackers Don't Matter" wanted Moya to generate as much light as she could, and used hypnotic patterns in the light generated within the ship to set the crew against each other. We don't find out what he wants the light for, only that it has something to do with what his species wants and they seem to be a threat to everyone else (even though, after he's killed, we never see anything like it again).
 * Merlyn's turn as an avenging angel who still dresses in holy white on American Gothic, in the episodes "Inhumanitas" (a dead giveaway by its name) and "The Plague Sower." The fact the latter is a callback to the The Bible and a reminder that this trope is Older Than They Think doesn't change the fact she's left good behind--it takes Caleb revealing to her how she's become Not So Different before she returns to her usual self.
 * In one of the Season 6 'Immortal of the day' episodes of Highlander the Series, the villain is the head of a global charity organization, always seeking donations and preaching hope, charity and mercy. When he ambushes the main character in a carport with two henchmen, this bit of dialog happens:

"This is Mr. Hope, and this is Mr. Charity. Mercy has the day off." * shooting commences* "


 * An episode of Star Trek: The Next Generation had Data and the Enterprise computer infected by a program from an archeological artifact, forcing the ship's crew to play out an ancient ritual of a sun and moon exchanging places in the sky--from day to night, in this case. The ritual depicted the soothing, gentle moon convincing the harsh, burning sun to leave the world in peace for a time, to keep the sun from destroying everything.
 * Another episode, "Justice", has the enterprise discover a utopian planet of healthy happy people who wear white and enjoy sexual intercourse. Everything seems peaceful and perfect until Wesley gets sentenced to DEATH for falling through a green-house window.
 * So, how are they evil?
 * Ambiguously evil, perhaps. It's "evil by comparison" or simply differences in society, specifically a Protagonist-Centered Morality based around the Federation (and our morales as humans) as the protagonists. So by our definition of good and evil, the bright and cheery utopia matches this; there is deceptive peace and calm with an underlying evil of death as the only punishment.
 * Over-thinking it, lad. Anyone who wants Wesley dead has to be good.
 * Supernatural makes a point out of doing this with all the angelic characters featuring from season 4 onwards:
 * Early in the series, an "angel"  made people commit murders for the sake of considering them evil. He manifested himself surrounded by light,
 * Contrast the Winchester's angelic ally Castiel with Uriel in "It's the Great Pumpkin, Sam Winchester!" Uriel is fully willing to destroy the Adventure Towns that Sam and Dean have stumbled upon to stop the demonic baddie of the week from being raised (and a seal to the Big Bad's prison destroyed in the process), and he openly refers to humanity as "mud monkeys." Notably however Castiel would have helped destroy the town if ordered to, it's just he would have felt bad about it.
 * There's also Zachariah and his lackeys. At first, they just seem like smug, superior Jerkasses. And they are.  Zachariah also has another wonderful moment later: When   needs consent to take over   body, Zachariah gets persuasive.
 * Zachariah does mention, however, that heaven's plan was being kept secret from the "grunt" angels, implying many of them wouldn't have gone along with it if they had known.
 * In the season 4 finale, the ending makes a large change as it fades to white instead of black. Guess who's shining radiance is approaching?  Also, in the flashforward episode,   wears a perfect white suit and shoes.
 * Remember the Trickster? Liked teaching people lessons in very cruel ways, stuck Sam in a time look and killed Dean every single day?  And he's on their side.
 * The season 6 finale shows that even "good" angels are really evil. Dear God. It turns out that Crowley really is evil and working with Castiel to become the new God and Devil. And he's also working with the Archangel Raphael because he suspects that Castiel will betray him. He's right, and Castiel ends up becoming the new God, but he allows Crowley to live because he needs him. Castiel, though, feels betrayed that Dean didn't trust him to work with demons!
 * Crowley reminded us early on that Lucifer is an angel.
 * The final seasons of Stargate SG-1 saw villains in the Ori, ascended beings posing as gods (fire gods, really, but they do a lot of light stuff) and trying to convert the Milky Way galaxy to their religion (Origin) so they can use their collective faith to power-up and take out the Ancients. Their religion seems pretty Christianity-inspired, including having their own holy book (The Book of Origin) and inducing immaculate conception in a major character.
 * However, the Ori fire motif was eventually contrasted with the soft-white light of the Ancients, who also inserted the concept of "fire is evil" into almost every human culture.
 * But the Ancients themselves, while not evil are Stupid Neutral Neglectful Precursors.
 * In the fourth season, a beautiful, optical illusion-y light was used as an "opium chamber" by Goa'uld. It accidentally snared the main characters after its former users were gone.
 * Light seems to be a major theme of Heroes villain Adam Monroe, even after he becomes a Fallen Hero. So much so that the episode where he is killed is called Dying of the Light.
 * There was a series called Brimstone. It had the same idea as Reaper, in which someone is forced to hunt Hell's souls because the Devil owns his soul, with Lucifer being a absolute magnificent bastard who manipulates several parties against each other for his own Mephistolicious entertainment. Point was towards the end of the first season, his royal hoofedness shows up in front of the hunter of sinners, and gives a speech about how even the most damned souls can be redeemed. He then looks in the mirror and realizes he looks like Satan, and says to the hero that the first Angel someone sees is the way they perceive every Angel from that point on. Seeing as the show only had one season we never found out if this was Lucifer mucking with the guy or not.
 * One character (The Mole) pointed out that she had been a loyal worshipper of Baal, but had been condemned to hell because Christianity had "won" (in the Series, at least).
 * True Blood's Fellowship of the Sun is a fanatical mega church that is raising an army to make war on all vampires. It's led by a preacher in a white suit. And their version of The Dragon is not above committing rape to make his point.
 * And they recently added Faeries to the list of creatures. (Sookie is part-fay.) Faeries that.
 * In the fourth season of Angel, is this.
 * In Pretty Guardian Sailor Moon,.
 * The Future Is Wild has bioluminiscent sharks appropriately called Sharkopaths.
 * It wasn't played up a lot in It's Always Sunny in Philadelphia, and it was a role in Charlie's play, not his actual persona, but this kicks in when you realize Dennis of all people was cast as Dayman in Charlie's play/demonstration of his memories of being implicitly molested. Dayman himself isn't evil being "a master of karate and friendship for everyone" (that would be Nightman), but Dennis is the person playing him.
 * In the Battlestar Galactica Reimagined, the visions involving the Final Five, are decidedly ominous even though the Five are clad in white robes and surrounded by white light. In addition, D'Anna is instantly struck down after trying to approach one of them. Yet the actual Five straddle more along the lines of Good Is Not Nice.
 * The Light Fae in Lost Girl are only good by comparison to the Dark in that they have some rules about feeding off humans.
