Maybe, this line from the Al-Qadim is applicable to Ao and Lady of Pain too?
The Great Gods are neither good nor evil, lawful nor chaotic. They are beyond such matters. Bravery can be found in the most noble faris and the most black-hearted assassin, and who is Hajama to turn his ear from either of them? Individual followers or churches may be good or evil, but the Great gods are above these quibbles. This sets them apart from common gods and heathen deities, who are usually lock-stepped into their believers' alignments.
