Why were the Vikings such vile people?

Viking work ethic was the sole reason for England's and by proxy America's success

We owe western civilization to the viking race and their genes in our blood

Because they had a financial incentive to be.

Over time, all groups of humans will tend towards sociopathic self interest.

Morality only exists at the individual level, societies will act purely in their own self interest.

Also, shit thread, OP.
