It is true that once you're dead you're dead. Your actions in life affect others however. (You are part of an enormous picture, the world does not revolve around you. It never will.) So say if you die saving the lives of others, as opposed to dying from inhaling cocaine laced with gasoline, one is going to be inspiring to others, and one if going to be a fucking joke. In short, a heroic death is a "good" death. We are all GOING TO DIE someday. Wouldn't you like to think your life and death meant something?
