Hate to pull the Godwin here, but it fits.
People during WW2 who dared to help those that were prosecuted for no other crime than being who they are were living in constant danger. Not just of being arrested or inconvenienced, but of being killed. Along with their family. Still, people did just that. By far not many, but surprisingly many. They sure as hell could not hope for fame and glory (especially during the first years when it sure looked like Germany would win that war), actually all they could expect is that sooner or later they'll be betrayed and end their life in a concentration camp.
Sometimes some things are more important than your convenience.
