In the case of my own country Sweden and the Vikings I think it’s clear that Norse paganism not only allowed the plundering and rape in foreign nations, it even encouraged it with the concept of Valhalla and the mortality system it had which saw war and dying in war as a positive thing. Now I absolutely know Christians have committed horrible acts in other cases. But in this specific case Christianity was a huge force for good because after christening the plundering stopped, the holding of slaves stopped, the public sacrifice of human beings stopped and society became better and more moral in several ways.

But that’s far away from my point. My point is that monotheism isn’t always bad and paganism isn’t always good. It’s more nuanced than that.
