What Would You Do As Boromir?

[Nikkolas]

And no I don't mean about stealing the Ring. I apologize for the plethora of threads lately but this was something that really struck my mind as I re-read TTT:

We of my house are not of the line of Elendil, though the blood of Numenor is in us. For we reckon back our line to Mardil, the good steward, who ruled in the king's stead when he went away to war. And that was King Earnur, last of the line of Anarion, and childless, and he came never back. And the stewards have governed the city since that day, though it was many generations of Men ago.

'And this I remember of Boromir as a boy, when we together learned the tale of our sires and the history of our city, that always it displeased him that his father was not king. "How many hundreds of years needs it to make a steward a king, if the king returns not? " he asked.

"Few years, maybe, in other places of less royalty," my father answered. "In Gondor ten thousand years would not suffice." Alas! poor Boromir. Does that not tell you something of him?'

'It does,' said Frodo. 'Yet always he treated Aragorn with honour.'

'I doubt it not,' said Faramir. 'If he were satisfied of Aragorn's claim as you say, he would greatly reverence him. But the pinch has not yet come. They had not yet reached Minas Tirith or become rivals in her wars.'

There's a lot of sticky morality in LOTR/The Silmarillion that ties into heavy real world arguments like the nature of evil, free will and God but this at the least seems like something a bit more tame but still interesting.

Say you are Boromir and you don't get killed by Orcs. Forgetting how the wider story changes, you head back to your home with Aragorn and now you are in the clinch. What decision do you make? Do you honor his kingship or do you stand by the line of the Stewards? Have they not done their best to rule Gondor for hundreds of years? Why does this stranger get to march in and take over everything?
