There seems to be a great deal of interest in the Vikings, even an enchantment.
But all they did was kill people and take stuff. Was it due to the cold weather and inhospitable conditions that justified it ?
Of course, this is not unique.
Hawaii chieftans killed each other regularly until the islands were united under 1 king.
They had a paradise with plenty to eat, warm weather.
Stalin killed people and took stuff.
Hitler killed a lot of people, and took a lot of stuff.
