Then one might expect that Viking raids were eliminated when they converted to Christianity?

If one expected such one would be disappointed.

Christian Vikings terrorized the coasts and raided those who didn't pay the “Dane-geld” just as much as the Pagan Vikings did before them.

It was economics that turned raiders into traders - not religion.

[Houghton M.]

They didn’t become Christians until the late 1100s and 1200s. Christianized Vikings did not raid “just as much.” Whether the reason for the decline was economic or religious, one can argue. The transition took nearly two centuries—more than most places in western Europe. Along the way, a lot of half-Christians Vikings did what half-Christian/half-pagans might be expected to do.

But you can attribute it all to economics if you wish. Religion superstructure, economics substructure and foundational—good Libertarian or Marxist theory, take your pick.
