First A (then who nows).
He deduced that his father would have joined forces with the Consult in the end (as in fact the dûnyain did), but he chose not to do that. If he wanted to join the Consult then why kill Möe Sr.
Right. My take is that Kellhus really DID go insane on the Circumfix and thus chose the, "stop the Consult at all costs" path, which would otherwise make little sense to a Dunyain. I'm convinced, based on the books and the answers RSB provided, that it was A all along.
1. If it was just the Consult, it seems like Kellhus had a decent chance of winning the encounter. But it wasn't just the decrepit Consult he was dealing with...
The Dunsult combined with all those Skin Skies in the Golden Room means Kellhus is toast without some kind of trump card (Ajokli). I don't see how with his normal powers he could have survived unless he had a God on his side. This brings us back to another problem (if Ajokli was out of the picture)- he really should not have gone in there alone. If Serwa, Kayutas and some other heavy hitters were with him maybe he could have pulled out the win.
Right, he needed the Godpower Ajokli could provide, which is why he "struck treaties with the Pit".
Even if he had taken everyone out in the Golden Room, the Ordeal was still stranded thousands of miles in the barren North with no food and winter on the way. No matter what the Ordeal was going to die, but Kellhus at least could have translocated to safety. (Let's also not forget the effects on the Ordeal of eating Sranc, Man, and Irridiated man. Fallout tells me eating radiated food is not good for you)
Yeah, the TTT collapsed at the Golden Room. Presumably Kellhus could have escaped along with a tiny handful of survivors he may have valued, but that's about it.
2. There apparently was no way for him to recognize the threat of Kelmomas. This gets into the free will vs destiny stuff but assuming he had killed the child that probably ends the No God possibility right then and there, at least for a time. He wins in that outcome. If he doesn't kill Kelmomas it seems like he is fated to lose.
I agree. Once he failed to kill Kelmomas, there was no scenario that didn't end with Kelmomas becoming the No-God and Kellhus failing. But COULD he have killed Kelmomas, or was it fated that Kelmomas become the No-God, period, full stop?
3. Kellhus knows about Topoi but somehow did not foresee Ajokli being very strong in Golgotterath and taking over? Unless he knew it would happen and was again, willing to take that chance?
Between Kellhus knowing more than any other man and the information in the Decapitants glossary entry, I have to assume that Kellhus was aware of the possibility. My best guess is that he either assumed he could prevent Ajokli from manifesting or that he figured that even if Ajokli did manifest, they shared the same goal of preventing Resumption, so yeah, it would suck for mankind (and probably Kellhus), but stopping Resumption justified any risk, any cost.
4. Even if Kellhus prevails in the Golden Room, he still needs to do something about the Horde 2.0 which is right there, facing a hemmed in Golgotterath Ordeal...massive problem for him to deal with even with his abilities.
The TTT ended in the Golden Room. If he succeeds in the Golden Room, the Horde 2.0 could devour the rest of the Ordeal and it would have been a success. Stopping Resumption was the goal, not preserving the Ordeal.
5. The big trouble with all permutations of this is that he is still damned at the end of it.
Maybe? He did strike treaties with the Pit and all, and he saw himself descending as Hunger in the Outside, so perhaps he'd successfully avoided damnation? The biggest question though is why take this path at all? Best case he's saved humans from extinction, but consigned almost everybody alive to damnation, including uncountable numbers of future humans. Hard to explain this decision on the part of Kellhus other than throwing up our hands and saying, "He went insane!".
