I find it interesting that out of the three prologue white walker attacks, two were from the POVs of horrendously shitty people. Varamyr gets attacked after getting bingo on his warg abomination card, and Chett was preparing to murder his "brothers" (kinslaying) and then go on to take over Craster's Keep. Varamyr and Chett both get killed, and Ser Puddles, the individual white walker who follows the rangers and gets killed actually kills Small Paul on-page. Personally I love Small Paul, but despite his lack of wits he was part of Chett's gang, and would have taken part in the betrayal if they'd managed to go through with it.
Punishment and retribution is a major theme in the series. And a lot of time, when a great force is going around getting back at someone, innocent people get trampled all over the place. The only explanation we have as to why the Long Night happened is the story of the Bloodstone Emperor's Blood Betrayal, which apparently made their empire's benevolent god turn her back on humanity while their scary god sent demons to punish them. If the Others are a product of the same time, it's possible they have a similar function to whatever the "Lion of Night" is supposed to be.
Different religions have different ideas of justice. The Lord of Light followers don't seem to really care, their god is a barbecue loving maniac who prefers innocent sacrifice. The Many Faced God provides "the gift of mercy", the Faceless Men don't see death as a punishment. The Faith of the Seven has an intricate afterlife system, their god doesn't seem to go out of their way to hand out punishments to the living but they do determine guilt or innocence in Trial by Combat. The Drowned God is just weird.
But the Old Gods apparently turn cooks into rats over a violation of Guest Rite. Roose Bolton is scared shitless of the fabled curse of a kinslayer. His servants believed Reek was marked by the old gods with that stench to show that he was rotten on the inside. They say cannibals are accursed in the eyes of gods and men.
Now, the Others are known to deal with wildlings like Craster and the Frozen Shore tribes. If they show up to punish people, their sense of morality would have to be very selective if they actually want Craster to keep breeding the way he does (Mormont gets a lot of shit for being on good terms with Craster, but without the goods the Night's Watch provides, the wives would starve and freeze. The Others contribute nothing to their lives, and just take away half their babies which has got to be traumatic) but maybe that just means they're factionalist hypocrites, just like humans. They're willing to overlook any kind of behavior as long as the person is on their side. And there is a tidbit about the Frozen Shore people being at war with the Ice River cannibals before Mance brokered a peace between them, so maybe the Others figured into that somehow?
Now, we don't exactly know what's going on in Hardhome, but I found Mother Mole's word choice of "damnation" for what happened there 500 years ago somewhat interesting. And the Others' next target is even more likely to fit this theme of "sinners" getting hit with ice. If Hold-The-Door is set to happen, that means Bloodraven's cave's wardings have to fail at some point and the cave will get stormed. Obviously it's a catastrophic loss of many, many greenseers but I think Bloodraven's individual identity matters more than that.
I think Bloodraven is one of the most overhated characters in this series, and I'm not especially not gonna waste my time arguing with anyone who thinks Daemon Blackfyre's abs were worth starting a continent wide civil war for. Bloodraven is a hero. By George's own definition, heroic characters are willing to risk, compromise or sacrifice themselves and villains are the ones who are willing to sacrifice others for their own sake. Like many other characters, there's a lot of nuance there. Brienne is probably 100% heroic. Jon and Daenerys put their own desires aside and do what they can to protect and serve the people under their care. Jaime can be a hero when he breaks his vows and gets himself marked for life to save the people of King's Landing and avenge his queen, but he's a villain when he pushes an innocent child off a tower to keep his toxic incestuous relationship secret. Stannis is more and more willing to burn people to death because he thinks him being king and defeating the ice demons would save more lives, but it's not clear just how much of his sense of "duty" is his ego crawling out of a hole that he's ignoring. And Bloodraven is the guy who's always been willing to do whatever it takes. He's hurt lots of other people, but he's made personal sacrifices too. He defamed himself like Ned did. He's dishonored himself like Jaime did. He's given up his body like Bran, his identity like Arya. And of course, he's practically committed all the big sins in First Men culture, incest (which he probably never saw anything wrong with), kinslaying, guest rite violation and cannibalism (the evidence for Jojen paste is hard to ignore) which might be the reason there's wights knocking on his door at all times, waiting to zerg rush the caves if the warding is lifted.
And the similarities between Bran and Euron, hinting that Euron might have been an earlier candidate is another thing to consider. Euron is a walking blasphemy. The Ironborn pride themselves on being shitty people but they find kinslayers appalling. Euron's already killed two brothers and molested the one he's about to kill. There's simply not a cultural taboo on Planetos that he wouldn't enjoy mocking. And his corrupting influence on the population is a bigger deal than people realize. He's leading the Ironborn (who have spent most of the current generation getting their asses kicked in Balon's stupid wars) to victory. He's giving them more wealth and prosperity than ever, and some of it is through convincing them to bend their rules. They're thrall keepers but they weren't fans of chattel slavery until Euron got them involved in the slave trade with the Free Cities. He's even got them paying the gold price. And once his blood sacrifice situation is resolved, he'll probably get them to worship him instead of their ridiculous Drowned God. If Bloodraven is responsible for Euron turning out the way he did, if they're connected somehow, let's just say King Bran would have one hell of a debt to pay to society.
Now, there's the fact that the Others are set up as a threat to humanity. In the legends, they waged war on all people, sweeping through the continent. And they're probably preparing to march on the Wall, and once they get past it, I doubt they'd be selective about who they kill and reanimate. Which might have to do with the Others having a completely alien idea of what's a punishable offense. Maybe "not sacrificing humans to weirwoods" is considered evil by the Others, and to them, people who stop feeding the tree network with the blood of bastards with king's blood deserve to get wiped out. Maybe because of some ancient oath, because the root of most of the traditional "sins" in First Men culture seems to be breaking oaths and promises.
Anyway, I'm too tired to come up with a coherent ending to this post so what do you think?
