Above all, our supposedly "barbarian" ancestors gave us our values. Most of what they teach you at school is supposedly a bunch of "Romano-Greek" and "Judaeo-Christian" values; in fact, most of the everyday values that you (unwittingly or not) project upon your fellow man in interacting with him are Germanic (that is, if you are of Germanic stock, like myself).

Chivalry? Germanic warrior code. Insulted? Your Germanic feeling of honor calls for revenge. Loyalty to your best friends? There's that Germanic warrior code again.

But remember, cultural values are, above all, reference. Choices remain yours to make, and are subject to your discretion, mood, intelligence, wisdom, and so many more that is intrinsic to yourself and no other.
