It seems to me that every Heathen group eventually has a conversation about who is worthy to go to Valhalla. Someone inevitably insists that only warriors who fall in battle can enter Valhalla, and they decide it’s disrespectful to believe otherwise.
Perhaps the reason that conversation comes up so frequently is that warriors falling in battle and ending up in Valhalla is frequently mentioned by the lore left to us. Once a warrior falls in battle, Freya and Odin split the fallen between them.
There are a couple of considerations the people who posit the argument that Odin only accepts fallen warriors into Valhalla fail to make.
The first of those is that the lore we have available to us in the Eddas and Sagas contain myths that have been rewritten in the hands of Christian writers. It is very possible that the reason Snorri mentioned Valhalla as the heaven for those who die in battle was due to the Christian ideal of fighting for the kingdom of god, which was a prevalent ideal at the time he recorded the stories. Snorri may have simply excluded information from the Eddas because he was writing for a Christian audience – we have no way of knowing with any certainty that Valhalla was restricted to only warriors who fell in battle.
The second of those considerations is that Odin is a god of war and wisdom. It is hard to imagine a god of both qualities stacking his army with a single type of soldier. The best armies, in the human world, are comprised of a vast array of professionals alongside combatants. In American armies, there are professionals that focus on mechanics, engineering, technology, scientific research, historical research, and the list continues. Not everyone who enlists in the military will face combat – there are plenty of units that are noncombatant. That does not mean they are irrelevant to the functioning of the military; it just means they are best suited to working behind the front lines. If human intelligence has taught us that the best militaries are comprised of multiple units with a great number of professionals, who are we to say that Odin would only take combatants in Valhalla?
To try and determine who Odin would or would not take is arrogance at its finest. It’s like people forget, when arguing anything slightly theological, that we are not gods and we cannot speak for them. The only one capable of deciding who can be accepted into Valhalla is Odin himself.
To those who believe only warriors can enter those halls, I wonder what would happen if they entered the hall and found themselves face-to-face with noncombatants. At that point, would the fighters find themselves angry with Odin for daring to accept noncombatants into his hall? Isn’t this far more disrespectful than the people who believe that Odin can and will accept whoever he wants?
I think there are questions that people fail to ask themselves, and they get caught up in Odin’s aspect as a deity of war and all too often forget that he is also a deity of wisdom. There isn’t a single military on earth comprised of just fighters. Why in the nine realms would Odin exhibit less wisdom than humanity in putting together his own?
