Most of the people in Westeros are really, really beautiful. These people can be the best people you will ever meet in your life, but some of them could also give the order to decapitate you simply for not addressing them by the proper title. HBO's "Game of Thrones" gave us a really diverse range of characters in the show, and it has been recently proven through practical data-collection and survey.
Beauty does not always mean 'good'
New York Times attempted to answer the question: "Does beauty actually make for good morals, and vice-versa?" In storytelling, especially fantasy, it is usual to portray the "good" characters as beautiful (prince, princesses, unicorns) and the "bad" as ugly (witch, monsters, octopus-people).
This has been a common trope in fiction that persisted for years (lookin' at you, Disney).
So the popular news outlet applied the question to "Game of Thrones." They encouraged people to participate in ranking GoT characters based on two criteria: physical beauty and moral disposition. Sure enough, just as the show is genre-bending and trope-defying all throughout its narrative, the subversions also persist with the show's characters.
According to a report by The Verge, more than 92,216 people already voted in the poll. Now, the results are summarized in a graph with the vertical line corresponding to "beauty/ugly" criteria, and the horizontal line being for "good/evil."
Some of the results are really obvious, like Daenerys Targaryen soaring high above both the "beauty" and "good" baseline.
Jon Snow and Missandei are pretty much in the same plane, but both are "better" than Dany in terms of morality, albeit "less beautiful." On the opposite side of the plane you get the Night King and the Mountain, which seems to be universally "bad" and "ugly" by everyone's standards.
They've also noticed how behavior on the show tends to make the character's "beauty" rating drop a lot, even if they're anything but ugly.
Theon Greyjoy and Littlefinger, forgetting about their misdeeds for a while, are really undeniable charmers. But it's surprising how their actions dragged their "beauty" score down.
This is what keeps Cersei interesting
However, if you're looking for outliers, look no further than Cersei Lannister. She has been ranked extremely beautiful, and at the same time falls on the extremely evil side.
Perhaps this is what makes her an interesting character; a character that would make anyone's blood boil but at the same time admiring how she executes her every plan with grace. "Bizarre and unpredictable characters like Cersei are what keep us watching and talking about 'Game of Thrones' through every twist and turn," The Verge writes.
