From the beginning, Thor was doomed. The Norse gods were fated to die in Ragnarok, after which new deities would be born.
In Jeramy Dodds’s translation of The Poetic Edda, this final battle is described as
Wolf-time, wind-time, axe-time,
sword-time, shields-high-time, as the world
shatters and no one is spared by anyone.
Thor finds himself grappling with the Midgard Serpent, a giant snake that had encircled the entire planet. Thor bops the snake on the head with his magic hammer; the snake retaliates with poison.
[Thor] steps nine steps but is finished
by that serpent who has no fear of malice.
Both Thor and Serpent die.

Thor’s father Odin spent much of his life obsessed with prophecy. Convinced that great sacrifice would lead to wisdom, Odin stabbed himself with a spear and hung himself from a tree till nearly dead, nine days and nights. Later, he traded an eye for a vision of the future – who needs depth perception, anyway?
But Odin still brought destruction upon himself.
According to the prophecies, Odin would be killed by a giant beast, the Fenris Wolf. Like the Midgard Serpent, this wolf was a child of Loki. By rights, the wolf should have joined the pantheon. It would have been Odin’s ally.
Instead, Odin deceived the wolf – you shuck shackles as easily as Houdini will! But let’s try one more time. If you can’t escape this set, we promise we’ll untie you. We just want to see, so that we can all marvel at your strength – provoking his anger.
If Odin hadn’t been such a jerk, Loki’s children wouldn’t have hated him. Ragnarok would not have come. Thor might have lived forever.
Or perhaps not. Because Thor surely died again when he was forgotten. What good is a god without worshipers? Pious humans keep their deities alive.
It’s not clear whether Thor was ever really worshiped, but libations were probably poured for him. I’ve never studied spiritual husbandry, but I bet the occasional splash of beer onto the ground was enough to keep Thor ticking.
Then his people converted to Christianity. They’d celebrate Jesus instead. Thor might have been forgotten entirely except that a few Christian scholars, years later, decided that the old stories should be preserved. Which means, of course, that our knowledge of Thor’s escapades is laced with Christian stereotypes.
In Christianity, women have a clearly subservient role – Job’s wife was a replaceable possession; Jesus’s teachings were conveyed to us solely by men. It’s not clear whether the Norse shared these prejudices.
For instance, contemporary genetic analysis revealed that one Viking warrior – long assumed to be male because he was buried with weapons and the regalia of high rank – was actually female. (As soon as this discovery was made, members of our modern Christian-ish society decided that she probably wasn’t that great a warrior after all, even though her prowess had gone unquestioned until she was revealed to have two X chromosomes.)

In Thor’s greatest recorded battle, he wears a dress. Within the world of Norse myth, the burly bearded man smites giants, but so might the presumed willowy beauty. Thor was Thor, but someone you’d thought was Freya might be Thor as well. In duress, man and woman alike could conjure the passions of battle.

Thor limped along for centuries, partially resurrected, his stories preserved so that Christian readers would better understand the poetic devices used in Icelandic literature. Wasn’t until the 1970s that anyone strove to worship Thor back to life.
In the beginning, the white supremacist movement in the United States was closely linked with Christianity. Southern plantationers thumped their Bibles. Specious theories about Noah’s grandchildren were used to justify slavery.
(Noah drank too much. On a night while he was passed out drunk, one of his sons castrated him so that there wouldn’t be any more siblings to share the inheritance with. Noah was understandably upset, and declared that this particular son’s lineage would become slaves. A few thousand years later, a nation of ignoramuses convinced themselves that people with higher epidermal melanin concentrations must be descended from this son.)
(The version of this story that was eventually settled upon for the Hebrew cannon – i.e. the version in the Old Testament – is circumspect to the point of absurdity.)
The KKK hated black people, but they hated Jewish people, too.
In the 1970s, a subset of white supremacists decided that Christianity itself was a tool for Jewish mind control. Jesus was just another cog in the great ZOG plot! They reasoned that the whole love thy neighbor business was intended to make them weak, and that they’d been tricked into worshiping Yahweh, who was and always would be a Jewish god. They conveniently overlooked the fact that Christians had been murdering Jewish people for millennia.
They spoke out against cultural appropriation. White people shouldn’t latch onto other peoples’ cultures or beliefs, they said. Instead, white people should worship their own gods.
They decided that Odin and Thor were white gods. As though a person’s religion could be coded into DNA. As though your genes determined which stories you should believe.
Thor really was racist, it’s true – but he was prejudiced against the race of giants, not any particular population of humans. And even though Thor was murderously prejudiced against the giants, it was still considered acceptable for him or other gods to drink and cavort with them, or intermarry.
The modern supremacists who’ve claimed Thor as their own think differently. For instance Else Christensen, who distributed Odinist materials to prisons with missionary zeal, who wrote that “We, as Odinists, shall continue our struggle for Aryan religion, Aryan freedom, Aryan culture, Aryan consciousness, and Aryan self-determination.”

Thor first died battling a snake. (This sort of bloody end would grant entrance to Valhalla – as opposed to Nilfheim, Hel’s dark cold misty kingdom, final destination for all who died of illness or old age.)
Then Thor died ignominious, his followers having dwindled, his worship having ceased. For centuries, the mud drank no more mead for Thor.
But white supremacists still love him!
Were Thor to die again, it would be of shame.
