Minas Tirith
Boromir had always planned to go to Minas Tirith, and despite the consensus reached at Rivendell that it must be destroyed in Mordor, he urged the Fellowship to accompany him to Minas Tirith before going on to Mordor. As Frodo pondered his course from Parth Galen, Boromir privately urged him to use the Ring in Gondor's defence, rather than to "throw it away". Finally, he succumbed to the temptation to take the Ring for himself, justifying this by his duty to his people and his belief in his own integrity.
