It's not an inclination towards whores, Wilshire.  Agnake is refered to as the whore because you don't get anything for free...  the implication is that for each turn of good fortune you get a corresponding kick in the balls.  Akka constantly refers to this.  Prime example, every instance of luck that gets him to Ishual has corresponding horrific turns of bad luck - ultimately he gets there but its completely ruined.

PoN is far more circumspect in attributing any real agency to the gods - there are only mild hints - like this instance with Cnauir,  Inrau's possible intervention etc.  That doesn't mean it isn't happening.

Re; Gilgaol.  Remember the gods experience time differently.  Preserving Cnaiur at that point may be important for some later objective that is important to Gilgoal.  Perhaps ensuring certain important characters fall in battle due to Cnaiur's latter presence/influence, or something else - who knows what the gods want?  It's only speculation. 
But I do agree with locke that that scene is positively dripping with portentiousness.

Tend to agree that outside agencies might active here.  Crack-pot speculations to follow...

With Cnaiur I suspect Gilgaol or Lokung are the entities that would have an interest in him and manipulating events through him.
Gilgaol would be inclined to reward Cnaiur's personification of warlike attributes by leveraging events to allow him to wreak greater carnage (i.e. not die at that juncture) - and remember War and Birth alone may seize (so Cnaiur need not be an adherent to recieve the god's 'blessing').

Lokung as an outside entity I could see as a key to the creation of the No-god.  Explaining why the Scylvendi are important to the consult and their culture remains locked in a ossified and unevolving state.  Their existence and continued worship of their dead divity might be important to the no-gods resurrection and the manner in which Kellhus communes with him.  Considering Cnaiur's importance in revealing certain things to the consult after surviving the events in question, Lokung might have motivation in manipulating said events to ensure his reincarnation as the no-god. 

Disinclined to agree about Fate being the mover.  She seems depicted as the kind of entity that goes for ironic lols at the expense of her pawns.
 

Very worthy, Sci. 
Sorry I can't help - me being a dirty furiner.
