Beware the Honest Ones
In a series where the characters aren't really good or evil, there will be one who is an idealist. From the point of view of the others, that character will be completely untrustworthy; everyone else can be depended upon to act in their own self interest, but nobody can predict the idealist.
Compare Knight Templar.
- Matsuda from Death Note. He's honest and idealistic to a fault, and more often than not makes a nuisance of himself. However, his attempt to infiltrate the Yotsuba Group provides vital information, even though it backfires, and when Light Yagami reveals himself as Kira and starts gloating, Matsuda is the first to whip out his gun and start shooting. This is, incidentally, something like the true inverse of Bad Guys Do the Dirty Work—the closest surviving thing to a good person does the shooting.
- Suzaku of Code Geass - because of his idealism, he acquires a major case of Chronic Backstabbing Disorder.
- And Euphie, ultimately, but it's not her fault! This world was made for Magnificent Bastards. To break themselves against, like Cuchulain fighting the sea, but at least they have a shot.
- Mao, as well, tries to be as honest as possible, and he can see through anyone's lies because he can read minds; but he's a very dangerous villain.
- Tenma from Monster is deemed untrustworthy by his director for choosing to operate on the patient who came first, as opposed to the patient off of whom he'd profit more.
- Nao Kanzaki starts the Liar Game described accurately as "Foolishly Honest," meaning she expects everyone else to be just as honest as she is by nature. As the Game progresses however, Nao begins to prove herself perfectly capable of deception, and manages several Crowning Moments of Awesome through it. In fact, her lies have frequently relied on people being aware of her honest nature, since no one stops to think she might be lying.
- Xellos from Slayers. He never lies, nor does he disobey an order. However, he will often leave very crucial details out of the information he gives and use all flexibility he is given to further his own goals.
- Tamiya attempts to wrest back control of the Litchi Hikari Club from Zeera once the group approaches the Moral Event Horizon. Very fittingly, his epithet is "Bullet of Truth" and he is often shown as the most obviously upstanding member of the nine.
- Ozymandias from Watchmen. No one saw that coming.
- More than once, Batman has had to keep facts from, and even lie to Superman or the other members of the Justice League, because he believes they are too idealistic to do what sometimes needs to be done. Notice that he never looks down on them for being that way, however (Depending on the Writer.)
- Jack Sparrow hangs a lampshade on this in the first Pirates of the Caribbean movie. In the third movie, he pulls it off himself: Pirates can only be counted on to be greedy bastards, which is why there hasn't been a Pirate King in a while (the position is democratically-elected, and they all vote for themselves). So when the vote comes up, Elizabeth wins by one...
- Maximus in Gladiator.
- Pointed out by Captain Hook
Me lie? Never! The truth is much more fun.
- In Audrey Wait, the protagonist uses her national, live TV interview as a chance to spill the beans on everything leading up to this point, thus dispelling the gossip and rumours surrounding her (and helping out her friend Evan in the process by exposing their duplicitous label - on live television).
- Victor Cachat, the young spymaster for the New Republic of Haven in the Honor Harrington series, is an idealist. He puts himself through and into Hell over his moral issues. He is also the most ruthless SOB in the entire setting when he needs to be.
- In Dan Abnett's Gaunt's Ghosts novel Necropolis, Sturm's attempt to make his plans without input from the other Imperial Guard officers is betrayed by Daur, who merely says, in his defense, that the officers had the appropriate security clearance.
- In Kerry Greenwood's Danger Do Not Enter, everyone hates Argent because she always tells the truth. When asked to clarify, Ben explains,
Ben: Jacinta asked if her new skirt made her bum look big and Argent said, "Yes." Her teacher asked her if she'd done her homework and Argent said, "No." When she was asked why, Argent said her stepmother and father had a big fight about sex and she was too angry to write about diatoms for her Biology homework."
Penny: Oh, I see. Ouch.
- Anaiya of the Blue Ajah in The Wheel of Time is described this way. Her lack of deceit continues to confuse the other plotters in the White Tower. Also, Cadsuane does this deliberately.
- Galad is probably the best example in the series of this trope. His step-sister says of him, "He always does the right thing, no matter who it hurts." He is introduced to the main characters and the reader when he calls the guards to deal with a peasant boy (Rand) who has fallen over the wall of the royal palace and is being taken care of by the crown princess. She's apparently in no danger, and her brother is with them too, and no one wants Rand to be possibly thrown in jail over an innocent accident, but to Galad the rule about how to handle intruders doesn't allow for exceptions. Later, he joins the Whitecloaks on the strength of their ascetic philosophy, even though his mother and sister are members of or at least connected to the Aes Sedai, who the Whitecloaks all see as Satanic witches. Still later, when he suspects that his superior officer in the Whitecloaks killed his stepmother, he kills him.
- In a perfectly legal ritual duel, no less, and gets Valda's rank and Blademaster status afterwards.
- Adviser Arfarra from Yulia Latynina's Wei Empire cycle might fit - while almost the entire Weian establishment is either corrupt or negligent, Arfarra is neither, but is instead a truly ruthless (but consistently, if not obviously idealistic) Knight Templar who has been described as being "capable of anything in matters that didn't affect his own interests" (as opposed to the character that described him thusly, who is capable of anything in matters that did).
- Carrot from the Discworld Watch novels frequently triumphs because he is so honest and straightforward that the scheming, backstabbing people of Ankh-Morpork don't know how to deal with him. (Being strong enough to knock out a troll in a bar fight helps too...) Later on he acquires a good dose of cunning but maintains the image.
- He's still scrupulously honest - in Men At Arms he's trying to get some information out of a Guild leader, and tells him, with a very serious air, that if the guildmaster doesn't do what he wants, he will, unfortunately and very much against his will, be forced to "carry out the order I was given just before entering." Said order? To leave quietly if the guildmaster refused to help. However, the guildmaster assumes it to be more along the lines of "break a few arms" and, in a panic, relents. This leads to the page quote.
- Cohen the Barbarian. Not because of his own honesty, but because he assumes everyone else is just as honest as he is. Thus in Interesting Times, when a soldier says, "I would rather die than betray my emperor", Cohen kills him. It doesn't take long for people to stop saying this unless they mean it.
- Sam Vimes, (Carrot's superior) also gets treated like this on some occasions. Notably, the city's Magnificent Bastard lord, Vetinari, has said that someone who is too honest to play the game makes those who are playing (like the city's nobility) nervous, and Vetinari finds that to be quite useful. Also, when Vimes goes back in time in Night Watch, Vetinari's aunt makes a similar observation.
- From Harry Potter, Snape doesn't really lie to Harry. He hates him, his father, his untameable hair. Harry needs to shut up the Wangst and train more. He doesn't really lie to Dumbledore. He was a Death Eater because he wanted to be one. He doesn't dislike the cause. He detests Muggles and his lineage. It's nigh impossible to lie to Voldemort. He even told him he fancied Lily Potter, Voldemort just wouldn't hear of it. Fans spent years debating whether his attitude yet conflicting behavior meant he was on the good side, on the bad side or on his own, but he was never that much of a Magnificent Bastard and his goal was never that complex. He was just a Death Eater who made a Heel Face Turn because he really loved Lily Potter.
- Meursault in The Stranger. It never occurs to him to lie, even to save his own life. Why would his life need saving? Oh, because he's facing the death penalty for having shot a man. For no reason. Unless "the sun was bright" counts as a reason.
- In Robert A. Heinlein's Time Enough for Love Lazarus Long comments that "business" politicians are usually honest (in the sense that they stay bought) whereas "reform" politicians tend to be stupidly dishonest, because they are capable of doing literally anything that they believe is in the best interests of the "People."
- Subverted in the works of Ayn Rand where the characters who serve their self-interest are the idealistic ones. The untrustworthy villains are those who claim they want nothing for themselves, and will steal anything for the "common good".
- Morgaine invokes this trope with her memorable statement, "With devils, there is dealing. Sometimes far easier than with an honest man." She has learned this by bitter experience.
- In A Confederacy of Dunces, Ignatius is not necessarily evil, but his convictions and rigidity drive the entire plot. At the very outset, his obstinance almost gets him arrested, and things spiral from there.
- Michael in Prison Break. Linc knows he is going to be executed but at least he has the satisfaction of knowing that Michael went to college and will have a good life. Except not because Michael cannot let Linc die for a crime he didn't commit so he gets himself sent to prison on purpose to rescue him.
- Michael's idealism is a source of conflict throughout the show. It takes place in a Crapsack World so they should probably run far away but Michael wants to take down the company.
- Star Trek: The Next Generation. Data doesn't lie. Supposedly ever. Which makes it all the more devastating when he does because nobody believes he can possibly be telling an untruth. An entire episode revolved around this concept with Data forced into lying by an order from his captain - who didn't KNOW he'd made the order. It even helped him get away with attempted murder.
- Survivor. After Phillip got stuck on the wrong side of an alliance war, he was asked about what was going down. And promptly told the entire plan, despite his fellow alliance members trying to use him as a scapegoat. This distanced himself from the losing side, and proved his honesty, enough to sucessfully join in Boston Rob's alliance. It has to be seen to be believed, and was one hell of a way to start Redemption Island.
- Played with a bit by Radical Honesty practitioner Eli Loker in Lie to Me. He's mostly harmless, just a little annoying.
- Saxony Canterbury of Thunderstruck, who forms uneasy alliances with a Knight Templar organization willing to kill for sex in a chapel, a witch who killed his sister for a Human Sacrifice and Satan himself...all for the sake of two teenage girls.
- The fact that Fighter is not a sociopath is often an obstacle the Light Warriors of Eight Bit Theater must overcome, such as here.
- Lampshaded in Tales of the Questor: After Quentyn agrees to take a high risk quest with no returning until its complete to fulfill an ancient contract it is revealed that the bad guys overlooked this simple possibility and consequently have no contingency plan.
- The Reverend Darren England, in the Whateley Universe stories. He's so idealistic and so concerned about protecting the planet from demonic threats that he hires assassins to kill a schoolgirl, which leads to an invasion of the Super-Hero School Whateley Academy. On the other hand, the girl in question is prophesied to become The Kellith, whose spawn will wipe humans from the earth...
- Interestingly enough, before the incident, she had already killed her own future self, theoretically negating that possibility. Also, if anything would make Kellith go evil, the stuff this guy does would.
- However, considering his 'hate-filled sermons', he might just be a straight-out Knight Templar. Him helping to rescue Kerry in "Angel in Father John's Basement" helps, though.
- The Business Plot, a reported conspiracy that intended to overthrow the American government in 1933 and install a fascist dictatorship, supposedly fell victim to this when the conspirators chose Marine Major General Smedley Butler to lead the coup. Butler instead chose to reveal the plot to the government, which fairly quickly brought an end to the conspiracy. You have to wonder how serious a plot it was to choose Butler since he had become famous for making radio addresses where he admitted he was ashamed of serving in the military and how it was used as a pro-business tool by the government. "Al Capone operated in three city wards. My Marines operated on three continents." He also was a socialist.
- Does that last part matter?
- On the face value, he was a vocal representative of the very faction the plot (if it did exist) opposed. He didn't have an obvious reason to jump the ship, and his "comrades" had reasons to not escalate the strife this far at that moment. What one could expect to see was exactly what happened: Butler exposes the plot, investigation sinks in "he said - she said" at step one, then Communist papers publish the widest and wildest version of it all as real anyway. Thus inviting Butler into an actual plot makes much less sense than this being made up, either by:
- Butler: to put pressure on the opposition and less-reliable allies using threat of a witch hunt. Perhaps mainly Morgan, as a target of some shadow war earlier (who knows who set that bomb near Morgan's bank in 1920?) and at this point could be an unwilling "ally". Or
- MacGuire: to put pressure on Roosevelt & Co. and hopefully slow down their triumphant march using threat of a non-existent hostile faction. While adding some suspicion and schism in the enemy ranks, by implicating some in the veterans' organization (Butler's power base) and Morgan (see above).
