It's safe to say that 100% of the Northmen who invaded England in 1066 shared that same "job description", however.

99%.

Poor Sven just liked maps but they kept making him come along on their “excursions”.

By 1066, not quite. That was an invading army led by the King of Norway to press his claim on the throne of England. I’m sure many of the soldiers in that army had been Vikings but at that time they were soldiers of a Christian king, which would have been considered much more legitimate than being a heathen raider.

I guess the Normans were also of Nordic descent but they had given up the Viking way of life a century before.

What's gonna bake your noodle is, Viking raids were the VC-funded startups of medieval northern Europe. Norse kings were very generous with their kingdom's treasure, to the raiders with the most fearsome reputations.
