So this leads me to another question, why didn't the ring try to tempt Aragorn? He wanted to go with Boromir to help deliver Minas Tirith from Sauron so why not tempt him? Is it because he is Isildur's heir, and had a "right" to the ring or is it because he is of noble blood, or what?

I would like to say this of Boromir, I never have thought of him as evil or weak. I see him as a man with a great love for his people and homeland, who wanted to help his people so desperately that the ring used it against him.
