>>19290465>Basically those who can see the future in 40K generally only see glimpses or visions of it rather than full versions of it. Likewise just because you know something is gonna happen doesn't mean you can stop it - Easiest example for that is if I just came behind you with a gun there isn't much you can do to stop me from shooting you. On top of that the Chaos gods can also see the future or at least Tzeench can. So in such fights you have 2 groups trying to influence the future of what would be if they had not known about the prophecy ending up causing a completely different future. That leads us to multiple possibilities:>(1)He didn't see the part of the future of them getting abducted>(2)He did see it but also saw he'd get them back so he thought that's OK>(3)He simply couldn't do anything as the 4 Chaos gods combined are stronger than he is.true, but this however brings us back to the original issue: if he saw only glimpses and imperfect visions, how did he decide that keeping everything secret was the better option? By the time he got the primarchs abducted and then got them back he must have know that his visions of the future where flawed or at least partial and thus fallible, even discounting the millennia of previous experiences he likely had.
He knew about the chaos god and knew they could see and influence the future. He knew some primarchs would turn on him. On what basis did he decide to not warn anyone? The vision of a "worse outcome" may as well have been a trick of tzeench. The reality is that he failed to trust his own creation and got shafted because of that.
As for the looming galaxy wide catastrophe, it is the only plausible excuse, which still doesn't however justify keeping your primarchs in the dark about chaos (and the eldar webway), especially if it's necrons or tyranids, which are basically the antithesis of chaos
