I would offer to you that the truth may be more complicated than that, in a positive light, and that it might be a key to us walking our way out of civilization.
There's a couple of places where I've noted in my studies where wilded societies attempted to adapt to the new technology of cities. Daoism would be one. Shinto. I believe the druids were an attempt but the Romans saw the druidic power structure (which was highly political in nature) as a threat to their own rule.
The brothers who helped Odin with Ymir; their names represented the kind of will / intelligence needed to overcome a threat and the strength to carry it through. However, it was Odin, the divinely inspired poet, who won the day and I'm sure you noticed that he did this by re-framing everything. If it stopped there, then yes, I'd see him as a colonizer, but the old stories include him adopting the son of a giant, having sex with giants, marrying Vanir. He wanted that relationship with the earth, even as he recognized that their way of life was at war with it. I think, in that context, Loki was his greatest success.
One of Loki's children was an apology to Odin for messing things up, which likely enabled some of Odin's greatest deeds (like discovering a universal language / writing).
Loki's more infamous children were the Great Wolf, the World Serpent and the One who Watches the Dead. They're the ones I'm thinking about.
His sons: Fenris, the threat to Asgard, who represented heavenly wrath and anger and righteous fury gone awry, only able to be stopped (temporarily) by sacrifice and the power of dreams. Later, only the master of poets could defeat him, but at the cost of the death of words.
Jormungandr, who represented the dangers of the material world. Consumption so profound that it spanned the world and could not be stopped. A monster familiar to those fighting the "black snake" in North Dakota today (sideline). Unlike Fenris, they couldn't figure out a way to contain it so they ignored it. Only the power of the storm ultimately overcame it.
Then there's the daughter. Never fully born. Half dead. Hel, in charge of those who lived half-a-life, who never fully embraced their spirit, their own individual fates. She took care of their anger at being judged, at wasting their time in the Middle World. She contained their memories and desires to be made whole. And when the time came, she released them to work their own kind of judgement on the world. She was never overcome. Then again, she was the gatekeeper.
In the wake of Loki's critique of Odin's world made flesh, the carefully constructed balance was shattered and then re-born. Another chance given.
I'd like to think somewhere, the trickster loves the new world, out of his control and those of Asgard and has reconciled with his adopted father, still reeling from being eaten by a wolf.
I was talking with my kids and reflecting on how Ymir had to die, for time and the universe to start. But that was also a horrible tragedy.
Odin won by tricking Ymir into death, by naming Ymir out of existence. Ymir's sons reflected Ymir's power but only Loki, Ymir's grandson, reflected Ymir's death. He was in the form of Odin. And in that form, he both honored his grandfather, avenging Ymir's death, and his adopted father, by setting the stage for a different world from the last.
He's the villain in the story because the skalds recognized that you can't -encourage- that behavior because it will lead to disaster 9 times out of 10. But I think they preserved it, hidden there, for us to find it when we looked.
I suppose I'm posting this because I see an opportunity for us and hope we can further the discussion by pulling in what is, what was and shape it into what will be.
