Don't pick on Valley Speak.

And HOLY NERDS, BATMAN!!!

Still and all, Boromir exercised his own free will. And redeemed himself at the end.

"He died to save us, my kinsman Meridoc and myself, waylaid in the woods by the soldiery of the Dark Lord, although he failed and died, my gratitude is none the less..." Peregrin

First of all, I offer my two cents based entirely on the books. To discuss the deeper themes in Tolkien based on the movies is like forming your theology of the Gospel of Matthew on a song from Godspell.

In Fellowship, Tolkien states plainly that the temptation Galadriel exposed in each of them was first and foremost tempting them with somehting already in their own hearts, and the choice offered was between remaining true to the Fellowship and continuing on, or to "turn aside from the road and leave the Quest and the war against Sauron to others". And she already had warned them as to why she was tempting them -- because the Quest was in peril and would only succeed if the company remained true. She did it to make sure they knew what they were up against, and to make sure they had searched their own hearts and were certain of their faithfulness to the task and each other. I don't think there's ANYTHING in the books to hint that she intentionally WANTED Boromir to react as he did, not to light a fire under Frodo or for any other reason. It's clear that the seed of temptation had already been planted in Boromir all the way back at the council in Rivendell, and it came to a head at Tol Brandir, but it was not egged on by Galadriel, and if anything, she was offering Boromir one last chance to shun his temptation.
