>>96236355>Unfortunately he didn't create the Primarchs intending for them to be immune or resistant to Chaos corruption, so the mere knowledge that Chaos exists is already too dangerous and would immediately corrupt half the Primarchs. Why? Who knowsI am somewhat partial to the (objectively shit, but kind of thematically fitting to how Imperium's often written as doing horrible things by necessity, not because of evulz) theory that he had relived the Heresy period so, so, so many times using psychic fuckery, that the current path is simply the most optimal. He's just so discontent with the optimal path being fairly horrible, that he does the bare minimum to make sure things happen right. He could make the Primarchs Warp-resistant, but that, perhaps, leads to them eventually deciding they don't feel like stepping aside for humanity to live, and they end up tyrants and satraps, waging endless war between their kingdoms of mankind until tyrannids show up and kill everybody. So, no warp resistance.
Or, for instance, he could play out a more complex and detailed path for Magnus to fall, because Magnus must fall, but he hates the fact that it is so; he likes Magnus, Magnus is the closest to him in many ways. So, he simply does the requisite steps without any obvious logic or spirit to them, and is as obviously and offensively weird about it as can be.
It's all a sad necessity, fate requires it, but that doesn't mean that he has to respect it or put serious effort into it.
