Galadriel's intentions.

[ninlaith]

That is an extremely good question. I only wish I had the best answer suitable. but i suppose I only have a mock up. I think Galadriel's intentions were of the best kind. However, i believe her motive was to try to 'break" the will of each of them; such as she did to Boromir. She awoke in Boromir, as you say, "a sleeping giant" so perhaps she was testing to see if this giant was withi each of them. If they each had this sleeping giant the quest would inevitably fail. I believe she wanted to test each of them before they went any further in their quest.All the bribing was just to sweeten the deal. She made the temptation even worse with her promises which, evidently, shook the faiths of each of the members of the fellowship. So, all in all, her planned worked and proved to be successful in some cases.
