In Tolkien's writing, the one often follows the other - Galadrial, for example, only achieves peace when she finally choses to 'diminish' by giving up her place in Middle Earth and returning humbly to Aman. Gandalf is 'wiser' than Saruman; rather than following his ambitions, he continues to serve his masters and purpose. Faramir had already made the decision not to take any kind of 'weapon of the Enemy' before he knew about the Ring. And when he found out - when Sam dropped the ball - he basically said 'Naw, don't worry, I've already made my decision. Keep that thing away from me.'
It's not that the Ring couldn't have done anything to snag him due to some inherent ability/point of his character.
It's that the Ring never had a chance to do so, because he made the decision that he wasn't interested due to a point of his character. He never looked at it, never considered how it would help because he didn't think it would, etc. And never stayed in proximity to it. Basically it was more of a Gandalf choice - 'I'm not going to give the Ring a chance to do that to me.'
