The Vikings Are Generally Regarded as Being a Destructive Force

The Vikings are generally regarded as being a destructive force in European history:

A) but such a view may not be correct in light of the principalities they established across northern Europe.
B) as evidenced by the raids they staged on virtually every population center in Europe from London to Paris to Rome itself.
C) because of the destruction caused to many great monasteries throughout Europe and the accompanying loss of the libraries in those monasteries.
D) but this has been exaggerated since they stayed mostly in Scandinavia with only a few raids into England and northern France,destructive though those were.
E) which is true,but they have an undeservedly bad reputation when compared with the Magyars who conducted raids into western and southern Europe.
