 I think the movie makes it a little ambiguous as to who is throwing out the men from the windows at the beginning.  When Vadinho shows the picture of young Tony with his parents, he says `in those days I didn't have to kill to find you`.  And he *is* the one who chucks Tony out the window.  Either way, the hero never has a `wait, what's this about killing?` moment and Vadinho's comment is never mentioned again.  I'ts also unclear how the defenestration would help the villain's gang.  Since the one person who would survive the fall is the person they want dead, they would still be faced with the chore of finding another way to get rid of him. 

 Since this article has a trivia section, you could also update it to reflect the fact that despite the explicit references to Aztec mythology, at the end of the film, Vadinho says that the mask will be returned to the Andes, meaning this should have been an Incan myth.
