I like the OP's idea. There's a certain horror waiting for the souls of the dead, and this changes the nature of the 'benevolence' of the forced conversion. It doesn't create a post-life 'Heaven', but it might be better than the alternative of what a person goes through when they die a natural death. The fact that humans keep creating new souls to feed into the pit is even more horrific. If there was some continuity for the consumed soul (instead of mere obliteration), that might even be seen as even more benevolent.
The logic is similar to why you put a pet to sleep as they fall too ill.
Further to play with within this idea is the fact that the 'nids create so few intelligent, sentient organisms (when intelligence is such a stupendously valuable tool). Each sentient organism created is at risk of being 'caught' by Chaos (even if the Shadow makes it unlikely). The Ymgarl Genestealers might be part of this tragedy.
