You are hearing a lot of "it depends on the cause". A hero would be great in the eyes of this world, I get that. The attention would be fun for awhile, but heroes have great responsibilities after the complete their great achievement. Often, in our societies today, their human nature keeps them from maintaining that status for very long. We have too great of expectations for them.
A martyr that dies for a worthy cause is a role that interests me. Of course, I would like to choose the moment, but then it might never happen for me. Many martyrs today die for causes that I do not believe are worthy even though I know they do. If I knew there was better place on the other side and courage supernaturally held me together, that would be my choice.
