I think that this question should be rephrased to: 'what would have happened if Faramir had come to Imladris and would have set out with the Fellowship?'

I think this would have been disastrous, for if we turn the two sons of Denethor II around, it would be Boromir who found Sam and Frodo at Ithilien. What would have happened then? Would he then also try to get the Enemies Ring for the profit of Minas Tirith? I guess so, for I think that his lust for the Ring was beginning already at Imladris. Sam said (regretfully at first, but not that bad later on) that Frodo had the One Ring and I think that this would have stirred the same lust in his heart. His lust to gain the Ring and to be the savier of Gondor and the rest of the world. This would have proved disastrous for I don't think that he could have mastered the Ring. Besides if he would use the Enemy would know where the Ring was and he might have loosened all his power on Boromir and Minas Tirith (in stead of putting forth a small amount of his army first as he did, which is known as the Battle of the Pelennor Fields).

Well, this is how I think about it. Boromir of course did not deserve to die for he was valiant and strong (as we see in moria, where he is the only one with Aragorn to stand next to Gandalf to await the Balrog).
He was betrayed by his own love for his land, for that is the reason why he wanted the Ring so much, to save Gondor and most of all Minas Tirith.
