What if the Scandinavian Bible is wrong, and Loki is not evil? Let's use common sense for a moment, and think that Loki is the brother of Thor. They are both gods. Thor is the god of warriors, and Loki is the god of tricksters and deceivers. If we use common sense, Loki can trick and deceive the enemies. In a war, you need brute force and deceive to win. As far as I see it, the jews managed to rewrite the Scandinavian Bible and make Loki, the brother of Thor, to become evil, in order to deceive everybody.
