Boromir's ultimate, freaky motives...

[Thinlómien]

Why did Boromir go to Rivendell?

This has been troubling me all the week.

Yes, I know the book says that he went instead of Faramir because he insisted so and believed he was the better one to do it, and he had more strength.

That's maybe enough for some people, but not for me. What was Boromir's motive to take the task? Why on earth did Denethor let him go?

Wasn't Boromir the most important commander in Gondor's army? Both Boromir and Denethor should have known it. Consider the disadvantages of sending such a commander to a far land:

The soldiers' morale will decrease
1) They will start to worry/wonder about their commander and form conspiracy theories.
2) They will say. "If a Big Boss can leave the war, why can't we?" They will grow restless.
3) The contact (trust, and maybe even love) between the leader and the soldiers has been broken and the new leader has to start from the beginning.

Why would Boromir want to leave the war?
- Did he think it was the sacrifice: he should leave the war to find aid from Rivendell? Did he believe so much in the dream?
- Was he too proud to give the task to anyone else? If he was, wasn't that stupidity at that point?

More will come, when I will use my brains more...
