The Underdog?!

It is curious how interested we are with Underdogs, we consider suicide stupid and not worth mentioning however, if someone is willing to die for ideals for something 'special' then this suicide or be it 'Last Stand' can easily become a legend.
Take for example the movie 300 it does portrait a Last Stand fight which has interesting stories however we like to make it seem more heroic then it was as like to do with many battles during the movie many odd creatures appear of which we know many would not have appeared but it would have been a fight between man and man only not with mis-formed creatures that seem to resemble something that came back from hell and which can take many hits without falling.
However we do seem to like that concept of the underdog winning or at least putting up a severe fight this concept in fact seems so attractive that we create new stories if they are based in Fantasy, History, Present or Future we love the concept of the 'Righteous' winning and seem to always have of course the Righteous is determined by the society in which we live at that time. This Underdog might simply remind us of the 'fact' that if you are fighting for the 'Good' side then we can win or at least severely harm our enemy it also seems to remind us of us being able to be able what ever we want or of our own power really it does not matter why but it is certain that we like to believe certain things of our 'Side'. That 'our' own Side is the 'Good' and 'Righteous' side.
