By the time you receive this message, news of our defeat will have reached the Earth. The creatures we were sent here to tame are untameable. The colonies we were sent here to reclaim proved to be more formidable than we anticipated.
Whatever you may know about what happened here today, know this: Alexei did not die gloriously in battle. I killed him. My pride killed him. My pride continues to consume me even now.
You will never see me again, Helena.
Tell our children that I love them, and that their father died in defense of their future.
— Admiral DuGalle's final letter, StarCraft: Brood War, shortly before he self-terminated
This death...This death is ours. We choose it. We deny you your victory.
—Huron-Fal, Flight Of The Eisenstein, shortly before overloading his internal reactor rather than succumb to a viral weapon
I would rather go out in a blaze, than give 'em the glory...

Suicide is man's way of telling God, "You can't fire me - I quit."
— Bill Maher
This is no time for suicide! We're about to be killed!

The teeth of his old enemies, these ancient brothers and sisters of a thing which had called itself Kurt Barlow, sank into him like stingers. Callahan felt them not at all. He was smiling as he pulled the trigger and escaped them for good.

"When you're wounded and left on Afghanistan's plains,
And the women come out to cut up what remains,
Jest roll to your rifle and blow out your brains,
An' go to your Gawd like a soldier."
"You can't have me."
—Chloe, Harper's Island
John: Aeryn, if Scorpius gets me...
Aeryn: I know. Shoot you.
"It is inside me. I feel it spreading, clawing at my will, tearing at my thoughts. It moves me against my will, to this cavern. Here it will end. I do not wish this, do not want my body to become a weapon for the Ing within me. It hates. It demands obedience. I will fight to the end. I shall self-terminate before I will become a pawn of a filthy Ing."
—D-Isl's Testament, Metroid Prime 2: Echoes
