Sheridan went beyond the rim because he 'understood'. So did Delenn so I think she would end up going out there as well.
[/quote] Illogical for several reasons.
1. Eventually, everything which lives also dies. Everything, even the First Ones, although they only die in conflict. Having either Delenn, Sheridan or Sinclair live longer than they expected would not only make the story illogical, but also diminish what they gave to obtain a better future. It would add a profit motive, present in the actions of First Ones, who more often than not lived to enjoy what they built.
2. If they did not die, they lived. Living, they would have wished to help their world. Such help did not occur, hence they did not exist. Many times again and again, their work was destroyed, rebuilt by others, destroyed again and rebuilt again, slowly improving.
Neither Delenn, Sheridan or Sinclair did anything to direct such events. In situations when they would have acted, they did not act. Hence they no longer existed.
3. Sheridan understood enough to change the future for better. To tell unconditionally that he "understood" would mean understanding something radically different from others. That is clearly untrue.
He understood the world just like others, and some probably understood more. He erred like countless others. He learned like countless others. Loved like countless others, but sometimes also hated, like countless others. He simply chose his direction well, had some good luck, and left behind a world somewhat better.
4. If understanding something would prevent death, countless people should be immortal, because they all understood something. Many leave behind a somewhat better world than they were born into. However, they all die, some without enough time to enjoy what they created. Besides, what happens to the world is never decided by one person, but countless people interacting.
5. Delenn hardly understood more than Sheridan. Sheridan hardly understood more than Delenn. Neither of them hardly understood more than countless other people. There was no qualitative difference. Many worked for a better future, sometimes at great personal cost, sometimes with little reward.
6. Last of all, to have them live longer, we would need someone to interfere. Most people who support this theory say that Lorien could have interfered. However, I would like to point out flaws in that aspect.
7. When Delenn asked how long Sheridan would last, Lorien answered in a manner which clearly implied death in about 20 years. Lorien told of its healing abilities being limited, and giving part of itself to maintain Sheridan (reclaiming that part would explain its coming back to Coriana). Telling one thing and knowing another is called lying. Hence allow me to ask, did Lorien lie?
8. Many people like Sheridan, Delenn and Sinclair might refuse any offer of immortality, if such offer contains the inability to help others (clearly proven by history) and living to see their loved ones die.
Sheridan might not accept such an offer, if that would include living to see Delenn die, living unable to assist, later see billions killed in the next Earth Civil War. Delenn might not accept such an offer, if that would include living to always miss Sheridan, living to see her children die, living to see the galaxy go into hell in a handbasket, living with the knowledge that she would be unable to help.
Valen might not accept such an offer, knowing it will forever separate him from Catherine Sakai. With him, there is however an even greater obstacle. If Valen did not die, the number of Sinclairs/Valens would constantly increase, and soon reach infinity.
Now that prospect is truly scary. An infinite number of Sinclairs would soon fill the entire universe, consume all energy, darken stars and block out galaxies, accumulate in black holes, and eventually cause gravitational collapse, leading to another Big Bang.
Given that Sinclair exhibited some cared for the world he lived in, he would not allow that to happen.
