Swaying of the primarchs

Now that we kind of have a feel on why Horus was the way he was we can now move on to more of what he did. It was no small feat for him to sway his brothers to join him. While he was a perswasive being to begin with it takes more than that. It takes ruthless abandon and a belief that what ur doing is right no matter what any body says. He turned his back from the emperors perfect truth, the secular perfection of his design. Where no one not even the emperor was above the one truth and that is that there are no gods there are no spirits or an after life, there is only today to live for. only the future to strive for, and no man not even the emperor was above that. But the day Horus turned his back on that one truth, all was lost. He accepted power from those beings that didnt exist in the emperors secular society. He became the harbinger of death to the universe, and he only took the brothers he knew he could sway with the power of his word and the temptation of all that which lied beyond in the relm of the immaterium. His brothers such as Angron and Mortarion, but the one i couldnt belive was Fulgrim. i am just now reading the novel fulgrim and it has given me great insite into why he came to horus's side. Really though it seemed hard for me to believe that a being that strove so hard to be perfect like the emperor in every way could be swayed to go against him. but in what iv learned so far it was that perfection that he was trying to emulate that was his inevitable downfall. He just couldnt stand not being perfet. though he might not have been swayed had it not been for the deamon artifact he found on the Laer's home world. ill elaborate more on this in later posts
