I'm betting many of you don't know that the many hobbies of vikings along with pillaging and killing were using make-up, braiding hair in elaborate ways and wearing accessories such as bracelets, necklaces ect whenever possible?
Sure do. The Norse had amazing metal smiths. both ins weapons crafting, and jewelry. From what I understand too, the migration era germanic spatha or longsword, made in the traditional pattern welding fashion was later used in Japan, albeit much more refined by that point. But it seems even amongst many other germanic tribes there were many many similarities. Probably because of an ancestor group but who knows. They all had variants of the same gods. Odin, Woden, Wotan, etc. Hell Wednesday is Woden's Day.
As far as Nord's attacking their own villages . . . that was not unheard of amongst the Norse. Even neighbor's farms. If a farmer was having ill luck on his farm, and his neighbor a little ways away was producing more yield, well, let's hope he can defend his farm. I'd imagine Nord culture doesn't parallel everything from old Scandinavia, as their god(s) are different, and as a result I'm sure their mentality would be different. But civil war is a different ball game.
