[Lord of the Rings] Why did the Council of Elrond allow Boromir to join the Fellowship?

IIRC, Boromir was express about his desires to use the Ring for the defense of Gondor. He also expressed contempt, or at least mockery of the idea of trying to destroy what he saw as a valuable tool. Furthermore, the Council was well aware of the corruptive influences of the Ring, especially on Men. So, why did they allow Boromir to join the Fellowship? Surely they must have been a little uneasy about his motivations? Plus, it seems unlikely that they would allow him to join out of respect for Gondor, considering how desperate the situation had become.

They trusted him because he was a celebrated and honourable hero of Gondor: a reputation he ultimately lived up to.

If we're excluding people for fear that the ring might corrupt them, why stop at Boromir? That was Frodo's thinking, anyway.
