I see. Well, no, I think the ultimate rejection is suicide...if I may become serious for just a moment here. That's a definitive and final form of rejection of oneself, of life, of others, basically of the whole shebang...although it's "normal" common suicide that I'm talking about here, not suicide done on behalf of a political or national ideal (such as the WWII kamikaze pilots or a suicide bomber, for example). The latter is not based so much on rejection as it is on the idea of "service" (to the nation or the cause)...and taking vengeance on a perceived enemy.

The kamikaze pilots expected to die anyway (even in normal combat conditions), but they wanted to do so in a way which would do maximum damage to the military forces of the Allies. You could say that the men at the Alamo did something a bit along the same lines...and they are celebrated for it to this day. (caution: I don't mean EXACTLY along the same lines...but Travis did give them a chance to slip out and escape...or to fight and die...and virtually all of them made the choice to fight and die. I expect, like the Japanese, they didn't want to look bad in front of the others who chose to fight and die. It was a matter of honor. If an American does it, he is celebrated forever. If a Japanese does it, he's regarded as a fool who died uselessly.

(It helps a lot, of course, if your side ultimately happens to win the war, as the Texans did...then you can say that the sacrifice was "not in vain". If you lose, then people don't feel so good about it afterwards.)
