Most of those sound fine, but in Amalj'aa lore, Ifrit is actually the Spirit of Death. Their warriors went to a pit in Zahar'ak when they were ready to die and would burn themselves do death. A cult formed and started worshiping the flames and the Spirit of Death and that's how the Primal Ifrit was formed. In that particular case it's probably simply religion.
As for Bismarck, I believe the Extreme mode quest for him enlightens on his possible origins. The chieftain of the Vanu Vanu mentions a monster that consumed the bodies of fallen warriors. They "decry" him as a monster, which is much the same way they feel about Bismarck, as he is a deity of destruction in Vanu Vanu culture.
