Star Trek: Deep Space Nine1993

Sloan:
[saying his farewells to his family] As I stand here, reunited with my friends and my family for one last time, I want you, the people I love, to know just how sorry I am for all the pain that I've caused you. I dedicated my life to the preservation and the protection of the Federation. This duty, which I carried out to the best of my ability, took precedence over everything else - my parents, my wife, my children. I lived in a world of secrets - of sabotage and deceit. I spent so much time erasing my movements, covering my tracks, that now, as I look back on my life, I find nothing. It's as if I never really existed. I cheated you all out of being in my life. And what's more, I cheated myself as well. Now, I know a simple apology won't change that. Still, I feel the need to apologize anyway. No tears please. My death isn't a tragedy; it's a celebration. In death I can finally step out of the shadows and prove to myself that I existed - that I lived.
