I might be wrong, but it seems to me that the norse pantheon was to a degree influenced by the romans via other germanics. Maybe our viking
@Runa 
could elaborate on that.
Thanks for the confidence.

Most likely the similarities between the pantheons come from a common origin.
Not that the Romans cannot have influenced the Scandinavians directly and indirectly through both gift diplomacy and returning mercenaries, which have brought new ideas with them.
Some have a theory that Freyja is inspired by Isis and Freyja’s cat-drawn carriage is probably inspired by Kybele’s lion-drawn carriage.

Nevertheless, having to survive in a hostile world, where you never knew when your neighbors got the bright idea to ambush you to rob women and livestock, would also cause people to develop similar characteristics, no matter where in the world they live.
In addition, a common origin from a nomadic warrior people would again be able to explain the similarities in mentality.
People do not change so quickly unless, for example if they change their worldview through a change of religion. And it wasn't exactly because Christianity turned Europeans into a bunch of peace-loving hippies.
Therefore, I think we can compare the Knights with the other peoples. They also lived in a world where the power of the state was weak and it was only just about to take over the monopoly of violence.
Therefore, they also had to be tough and fearless if they wanted to survive. Funny enough if I remember correctly, neither the Homeric heroes nor the knights had trouble crying as women.
Where the Romans and the Scandinavians' if my memory is correct, looked differently at that kind of effeminate behavior.
