Not sure how to take your post? You just stating that fact or are you saying that it's not altruism because they are doing it so they will be remembered as heroes? If the latter then I say bull. I'm sure the last thought that's going through their mind is not "I'm going to be a hero" but more "I have to save my friends".
He's saying they ARE to be remembered as heroes! Quit being so simple and taking peoples' post out of context so you feel you have some free right to attack them.
