If I were asked to pick between the Sins-verse Azulon and Yeneli as to which was the worse asshole of the two:
The daughter of Muspelheim would win in a landslide. Azulon is a powerful mage who rules the second largest country of a particular world. Yeneli is a dimension-hopping arms dealing nihilist who extends her action to willful repeated blasphemy and sacrilege by her people's standards and *gets away with this for a good solid couple hundred million years before anyone really notices how far she's gone with it.* They're both archetypes of abusive personalities, and in Azulon's sense he takes it to grander relative goals in real terms within the perspective of a world.
Yeneli is entirely personal with her actions but they literally *enable her to manipulate and siphon from a full seventh of the universe when she was already an equal to the already-born Freyja Vanadis and not-yet-born Odin Allfather in mystical terms*.
Azulon is an imperialist aspiring to rule with a boot on the human neck, forever. Yeneli would (and indeed does post-resurrection when realizing her blissful idyllic life was a dream and the fulfillment of Death's act of spite for Yeneli twice trying to murder her and only failing because Death really *can't die*) burn the entirety of existence to ashes purely to spite someone else because of a personal slight.
