Who is a Hero?

If we want to see a depiction of a sometimes misguided hero look no further than The Eagle (starring the one and only Channing Tatum).  Throughout the film we see many different rather horrific acts all done in the name of honor and Rome two things rarely questioned in film.  In fact in The Eagle and other Roman war movies of its kind that kind of violent behavior is praised and rewarded.  Also another possibly questionable hero is Elsa because even though it is never directly stated that people are dying winter does kill people and she does set off a winter people are vastly unprepared for.  Finally there is The Black Widow aka Natasha Romanov ex Russian spy with a bad past.  Her horrible past deeds are eluded to in a way that lets the audience know they are too horrible to speak of.
