Great take on the Emperor!I also imagined him with a beard, or facial hair.The Zeus and Odin parallel is quite spot on, as like both were known to have many heroic, godly/demigod sons (Odin to if less than Zeus).Zeus also was quite manipulative to as according to some, he actually had ulterior motives i creating his sons to cleanse the world of horrific monsters, spawned from Typhon and Echidna, or even Gaea.But in turn, many Ancient Greeks interpreted not Eris, but Zeus was the engineer behind the Trojan war (manipulating all, including Eris according to Hesiod) - as he caused the war, to kill of his demi-godly descendants, or their semi-godly descendants (The Emperor also planned the Primarchs to go against each other, to get rid of needless Primarchs after the Great Crusade, if not the Horus Heresy.)Odin also planned and manipulated others in good intentions, and committed horrible things in (ie preventing Ragnarok, or at least have humanity and gods survive).(The Emperor is even called the Allfather on Fenris)The Emperor also though has elements of Yahweh AND Satan (if th latter with the Promethean/Luciferian interpretation).The Emperor plays the role of Yahweh, compared to his super soldiers, especially Primarchs his angelic sons. Sangunius representing Archangel Michael, and Horus Satan/Lucifer, with the difference he defeats the Michael analogue.The Luciferian/Promoetheus side, is that he rebelled against the Chaos Gods - representing a particular twisted, fourfold version of God, Daemons being their angels - the Emperor stealing/tricking the Caos Gods on Moloch, going against them and like Satan/Michael in more sympathetic interpretations, is a anti-theistic figure.
