I'm sure "random strangers they know nothing about personally" made up a large portion of the Vikings enemies.
I'd also wager that the battlefield scenario that the Viking belief was developed around would simply divide everyone into "allies" and "enemies." So a killer who sees himself as following that logic would apply the same black and white logic, their victims being enemies in some personal war.
