Fair enough, I exaggerated a bit there, I was mainly getting at the fact that in the book Faramir's compassionate/gentler/selfless nature was kind of a direct contrast with the power-seeking nature of his older brother and father. To have him try and take the ring by force seems to remove the entire purpose of his character. He's practically just another Boromir but with a chip on his shoulder.

Faramir never needed to.

i have never found that believable - if the ring is represented as capable of corrupting anyone, why not faramir? why not send faramir to mordor with it, rather than frodo?

I mean there's degrees of temptation. I don't think that simply being in the ring's presence was generally portrayed to be an insurmountable temptation. Some situations were specifically mentioned as causing the ring's power over a person to increase (eg length of time someone used the ring would put them more under its temptation) so I don't see why it's so hard to believe that someone could send off the ring bearer. In any case if that's an issue for you, how do you get around other more fundamental issues, such as how eg Aragorn manages to escape the temptation?
