I agree. I would be a little disappointed if Ajokli was Cnaiur in truth. As bad as he was, he had some principles and focused his hate mostly on the Dunyain. To become the greatest evil known to man would be surprising to me. Ajokli also tries to ally with the four mutilated Dunyain which I cannot imagine Cnaiur going along with.. unless it was trickery, which does not fit well with his character... I don't know, perhaps Godhood scrubbed away his personality. That would be kind of a let-down.
First of all, welcome to the forum!

I would agree to you only when it comes to Cnaiür in PON. Cnaiür in TAE seems to have lost what few redeeming characteristics he had before (of course, this may be subjective).
I could see Ajokli-Cnaiür "allying" with the Dûnyain as trickery. He did convince the Serwë skin-spy he was going to fight for the Consult, so it's not completely without precedent.
And/or becoming Ajokli could have warped original Cnaiür's personality to an extent, yes (which I suggested as a possibility before in this thread). The trickery hypothesis does seem to be more satisfying, doesn't it?

Hopefully, he becomes a separate entity in Hell. One which may challenge Ajokli for ruler-ship of Hell 
Another interesting possibility...but if Ciphrang-Cnaiür was to challenge Ajokli
and win, wouldn't he have always been "Ajokli" due to the Gods' nature anyway?
