Star Trek: Deep Space Nine, Season 6

Benjamin Sisko:
At 0800 hours, station time, the Romulan Empire formally declared war on the Dominion. They have already struck fifteen bases along the Cardassian border. So, this is a huge victory for the good guys! This may even be the turning point of the entire war. There is even a 'Welcome to the Fight' party tonight in the ward room. So... I lied. I cheated. I bribed men to cover the crimes of other men. I am an accessory to murder. But the most damning thing of all is—I think I can live with it. And if I'd have to do it all over again, I would. Garak was right about one thing. A guilty conscience is a small price to pay for the safety of the Alpha Quadrant, so I will learn to live with it... because I can live with it. [pauses] I can live with it. [pauses] Computer, erase that entire personal log.
