>His galactic atheism plan was solid.
lol that wasn't his plan at all.
His plan was literally just to clear up the galaxy so he had enough breathing space to copy what the Dark Eldar did, sans the torture because their souls wouldn't be constantly leaking out of them. Everything, absolutely everything prior to shoving humanity into the webway was a means to that end.
Ironically, Fantasy already solved this issue. He should've just traced the Vortex plan from the elves to siphon out the Warp energies from the galaxy. The only forces in the galaxy that would oppose this plan at the time of 30k at the forces of Chaos, which are not in position to do anything, and the Orks who were thoroughly buckbroken by the end of the Crusade. The only downside from humanity's pov is that not every single Eldar would be killed, which they haven't accomplished anyways. Unfortunately that would still result in a 0.0000006% chance the Eldar would create Slaanesh 2.0 in 8 million years so it was a nonstarter for the Emperor.
