If the Urizen had possessed an omniscient view, he would have known that he had not been without a chance.
That chance had come when Horus fell into a coma from the old wound left by the Spear of Dionysus. That had been his most vulnerable moment.
The fragment of goodness within his soul had rejected and clashed with the other fragments, leaving him lost.
If Lorgar had seized that opportunity, he truly could have killed Horus's physical body in the material universe, forcing the Four Gods to choose him as their spokesman.
Moreover, at that time only the Sons of Horus had been guarding their father. They had been utterly incapable of stopping a betrayal from Lorgar's conspirators.
Beings like Primarchs were exceedingly difficult to kill. The Emperor had used unknown Warp techniques alongside his biological sciences to create these demigods who could walk among mortals.
Their physical bodies might be slain, but their essence could not be erased.
Like Ferrus, who had fallen on Isstvan V: his physical body had indeed died beneath Fulgrim's blade, but the Emperor had brought his soul into the Webway, where he led the Legion of the Damned onward in battle.
