Was Kellhus supposed to kill himself? (and other questions)
Kellhus is sent out of Ishuäl in the first book to seek and kill his father. Moënghus has "broken“ the isolation of the Dûnyain and is a danger not only to their secrecy but he also endangers the purity of the Logos with the magical dreams he sends.
So far so good, but what good is it to send Kellhus out to kill his father? This way, the problem will only relocate from Moënghus to Kellhus, because now Kellhus will be the one corrupted by the world outside the monastery.
So was Kellhus expected to kill himself afterwards? It’s never explicitly stated, but in the prologue of TDTCB, Kellhus looks back on Ishuäl for "a last time", which sounds like he didn’t expect to ever return.
This opens another line of questions because in The Warrior-Prophet, Kellhus remarks that the blood of the Anasûrimbor line is special. So are the Anasûrimbor like the best genetic line that the Dûnyain ever produced? Is that why Kellhus was to father a son before he left? To preserve the good genes? Also, why would a two thousand year old order of determinist monks care to keep something like family names? Wouldn’t that be something from the outside world that they would want to leave behind and liberate themselves from? The concept of families and royal bloodlines, etc.? Because they also don’t believe in sorcery, divinity and prophecy, etc.
Also, how didn’t the Inrithi nobility and scholars like Achamian immediately call out Kellhus as a liar when he introduced himself as prince of Atrithau? It is said that the royal family of Atrithau is called "Morghund" and Kellhus always introduces himself as Anasûrimbor. Every nobleman and scholar that is versed in politics and history should immediately get suspicious, right? That’s kind of like if someone came up to you today and said "Yeah I’m part of the British Royal Family, my surname is Pendragon by the way." For all people in the Three Seas, Anasûrimbor should be a name of legend alone, of the High Kings of old Kûniüri.
