If you can't guess already undivided for three reasons
1 - You know all that originally the idea for undivided chaos was each chaos god had there own little empire in the warp space similar to a galactic map with empires in diffrent section and the black space in between...well thats Malal's realm
2 - Malal is the true embodiment of chaos attack chaos itself it doesn't need some petty blood lust,they aren't controlled by some petty lust,they arn't spreading some deasise or of continually plotting they hate everything so much that they'll destroy everything and thats what chaos needs a group thats truly just around for anarchy.
3 - If your pawning of your soul why just give it to one little leader just go the whole way and put it with the true power.
I actually loved the idea for Malal but GW got sued over it by someone claiming infringement and as part of an out of court settlement scrapped the idea. They've sort of place filled with 2 gods but they've only very vaguely hinted at them
