What happens to the souls of Genestealer Cultists, or anyone who dies within the shadow of the warp?
Is dying to a Tyranid Invasion a get out of jail free card in terms of endless psychic torture by extra dimensional xenos?
Everyone who dies ends up having their soul torn apart by daemons in the sea of souls. You have a few exceptions, the astronomicon can dissolve your soul through burning pain, you can get sucked up into the machine spirit of a titan or titan analog, that's about it.
But if you die during a Tyranid Invasion, what happens then? Does your soul make it to the warp? How does it bypass all the "noise" ? Do we have any lore of this happening?
