Personally that's kind of missing the point of what drove him to the mountain, and what he had to come to peace with, at the end of TGS.
It wasn't "I'm going to die" it was "I'm going to die... And it wont change anything. I'll just be reborn to do it all over again, and again, and again.".
Honestly, Rand was one of the few, if not only, Third Ager who actual seemed to "get" what "The Lord Dragon Reborn" actually meant.
For everyone else their was at least a "chance" of a "happily ever after", and that their soul might be reborn in more peaceful times, but for Rand? It's always going to be "The End Of The World".
...Honestly, I always found it odd how no one seemed to get that when talking to him about TG. Like they thought the whole "born to fight the Dark One" was just a two time job for him.
I agree, my response to Joel was more around the Christ like comparison, which didn't relate so much to being called back to the Pattern again and again to confront the Dark One.
I get the impression that for most characters, they almost pay lip service to the idea of the Wheel, and Ages coming and going, without thinking through the consequences.
Harid Fel potentially understood what it meant, as he had a better idea of the Wheel itself, and that the Second Age would come around again, with the Dark One completely sealed away, but Rand's initial response to Harid Fel, before he thought it through, was I think reflective of most people's view, seemingly that these Ages haven't really happened before.
Even from the Second Agers, many didn't seem to really think it through, even the Forsaken, outside of Ishamael (who I think had as good an idea as Rand did in the end, just took the negative view of having to be called back again and again), seemed to think that the Dark One really would break free, even though there have all those Second and Third Ages in the past where he hasn't succeeded.
