Chivalry is certainly not dead... in Game of Thrones, at least. The hit TV series from HBO is a medieval fantasy and it features enough knights, lords, and ladies to fulfill anyone's feudal drama cravings. However like in the real world as well, chivalry, which is often referred as a knight's or nobleman's code of honor and morals, often takes a backseat when it comes to plots and schemes for the crown. As as a result, people, regardless of whether they are nobles or commoners, drop like flies in Game of Thrones. Thankfully, not all the major or living characters in Game of Thrones are devoid of chivalry. Here's how the remaining major noble characters measure up in terms of their chivalrous deeds.
Cersei Lannister
Cersei, while undoubtedly one of the most interesting characters ever in television, lives and breathes betrayal. She thrives in manipulating everyone and everything to always get the upper hand. By now, any promises she bequeaths carry no weight or truth to them... unless it is given to her children, of which she has none at the moment.
As such, Cersei has zero chivalry and only cares for herself and her children. Such a treacherous trait has led to her being the de facto villain in Game of Thrones now that the Night King is dead.
Euron Greyjoy
This Greyjoy came out of nowhere and just started raising all sorts of hell for everyone. The most destructive part about him? He didn't let his nobility get in the way of attaining what he wants. We can recall that he secretly usurped the throne from his brother, Balon Greyjoy, by throwing the old man off a bridge. Prior to that, Euron was a quintessential pirate. He loots, he pillages, he kills indiscriminately, and he has no respect for women, even Cersei. It's hard to imagine someone as boorish as Euron actually becoming a king.
Bronn of the Blackwater
Ser Bronn of the Blackwater wasn't always regarded as such. He was a typical drifter sellsword and mercenary with no allegiance to anyone but himself and gold. That is until he met Tyrion and Jaime Lannister. That did not change Bronn's outlook and attitude, but the Lannisters made him a rich nobleman while becoming "friends" with them in the process. However, it seems Bronn's honor and courage will be tested this season. After all, Cersei paid him to kill both Tyrion and Jaime. He has yet to betray his old friends... sort of.
Jaime Lannister
The golden boy of the Lannisters, Jaime has arguably one of the most dramatic redemption arcs in Game of Thrones or even in the books. He went from one of the most hated and despicable men in Westeros to a true nobleman who threw away his riches and opportunity to fight for everyone. It did take seven seasons for Jaime to come around, but we can see that he is the best version of himself now—at least in the battle for Winterfell. One could wonder, however, if Jaime would have redeemed himself had he not lost some of the dearest things to him such as his sword hand, his children, or his sister/lover.
Bran Stark
Bran... sorry, Three-eyed Raven, has long abandoned his human conventions. He's... uh... something else right now, and that means he no longer cares about any moral code or valor. It's a good thing he's not too troublesome about it because otherwise someone would have pushed him out of a tower window long ago... wait...
Still, despite however Bran sees the world these days, he somehow cares for the living. We still don't know what Bran wants or plans to do, so it's hard to tell where his true loyalties lie... or if he even has loyalty.
Sandor Clegane/The Hound
Clegane was one of the most feared men in Westeros, not only for his swordsmanship, but also for his appearance. Despite being generally hated and unloved, he still upheld his duty to royalty until he became fed up with it. Despite going AWOL and abandoning his sworn duty to the crown, he still manages to be good. Thanks to some good friends and the proper company, the Hound found his true calling, which is to fight for those who can't, or at least avenge them... violently and in the harshest way possible.
Yara Greyjoy
Theon's sister and one of the few strong and reasonable women in Westeros. Yara is no simple pirate princess. Apart from being a smart noblewoman and a capable fighter, she is also a caring family woman.
She proved this when she refused to abandon Theon at the hands of Ramsay Bolton. Despite that quest not going particularly well, Yara still displayed impeccable bravery and showed that she can be reliable in a pinch. In fact, she's a lot more dependable than most knights and noblemen in Westeros for that matter.
Sansa Stark
Sansa Stark was a product of strife and struggle. Her character is also an interesting case study of what women expect in society versus how society actually treats them. As a result, her rough womanhood has made her a crafty and smart political schemer. Of course, she learned from the best deceivers: Cersei Lannister and Petyr Baelish. Still, Sansa has managed to retain what makes her a Stark in the first place. Her love for her family and her people in the North has led to some positive use of her guile and political will.
Arya Stark
Based on what we've seen in the past seven seasons of Game of Thrones, the words justice and Arya Stark can now be interchangeable. Arya has witnessed how her whole family and loved ones were betrayed by schemers. Hence, she set out to gain the knowledge and skills necessary to bring retribution to those who wronged her and her family.
For this, Arya has no shortage of chivalry. She brings death to those who truly deserve to die, and not many people in Westeros can do that successfully.
Davos Seaworth
Davos Seaworth is a man who simply refuses to die. He's been through countless wars and even lost all his sons in them—heck, he even lost his king in battle, but Davos continues to survive. That's how far his loyalty and valor took him. It is worth noting that Davos was just a mere commoner and smuggler who only got promoted to a nobleman and knight thanks to his being instrumental to Stannis Baratheon's survival? Even then, he still remained humble and fair. He has no air of boastfulness or pride about him despite his nobleman status.
Tyrion Lannister
Tyrion was often insultingly called half-man by the people of Westeros, though he usually displays double the chivalry of an ordinary man. Despite his small stature, he has proven to be braver and even smarter than most. It's not just in the combat and strategy department where Tyrion excels. He's also proven to be one of the most decent men in the show, especially when he refused to take advantage of a vulnerable Sansa Stark. Any other man in Westeros would probably do otherwise, but Tyrion is different and special.
Samwell Tarly
Tyrion has proven that you need not be knightly or a capable fighter to display heroism. Samwell Tarly represents this notion even further. He is arguably one of the bravest and most useful members of the Night's Watch. Without him and his discovery that obsidian glass can kill White Walkers, Jon and others would have never repelled the Night King's invasion. Apart from those displays of wit and nobility, Samwell has also stood up for those who cannot fight. He even defended Gilly against some Night's Watch attackers, even if it meant his getting hurt in the process.
Daenerys Targaryen
It's pretty mandatory to place Daenerys so high in this list. After all, her reputation and her names precede her. She was one of the first few monarchs who actually cared about slaves and even freed them. Daenerys also liberated other many other oppressed people outside of Westeros.
She did become more cranky and merciless after landing in Westeros by burning those who did not subject themselves to her rule. However, what she's still doing for Westeros right now is for the greater good. Compared to Cersei, Joffrey, or even Robert Baratheon, she's a just and rational ruler.
Brienne of Tarth
Oddly enough, the knightliest of knights was never a knight until just recently in Game of Thrones. Brienne of Tarth was the ideal knight and perhaps one of the best representations of chivalry in the show, as well as in the books. She was one of the best fighters in Westeros, she believed in justice, she was kind, and she fought for the weak. It's too bad she was denied the status of knighthood due to her gender. Thankfully, Jaime Lannister was there to formally make Brienne what she should have been all along: the best knight in Westeros.
Jon Snow/Aegon Targaryen
Ned Stark has taught his nephew well. One would think that Jon Snow would have grown up to be a hateful and resentful half-noble due to his cover-up. It was a good thing that Jon defied all expectations and developed into the savior that Westeros needs. Jon, or just recently, Aegon Targaryen, is the embodiment of the Starks and the North. Without him, there would be no Westeros; he even went out of his way to save not only his kin and friends, but also his enemies. Apart from that, he knows the weight of promises and will never lie, even for a strategic upper hand. Jon is what an ideal lord of Westeros should be, and for that, he deserves to be king.
