Sometimes, a hero has to give his or her life for a greater cause. And sometimes, a hero's sacrifice is utterly pointless and in vain. What's the most utterly pointless self-sacrifice of all time?
Please include a picture or clip of this needless moment of self-abnegation. And let us know the title of the movie, book, comic or TV show in question, and why it was so pointless. Thanks!
