Who would sacrifice their reputation for the sake of the world?
lauranesson – it’s when he writes the book as the Speaker of the Dead, which implicates that Ender unnecessarily destroyed most of the alien race, that he sacrificed his own reputation as Ender for the good of humanity (it could be argued that his actions to de-hero Ender saved humanity for a terrible civil war, etc).
Alexander Hamilton. The duel destroyed his reputation initially and obviously killed him. But he did it for no other reason than he knew that getting Burr to particpate would also destroy his reputation as well. Once the duel was over Burr’s rep was destroyed and his political influence was negligible. All historical signs point to the fact that Burr was a genuinely pernicious influence on out nascent republic.
