One has to completely twist the evidence right there in the movie to say this is a pro-euthenasia movie. If that were the "right" position the choice the character makes would be shown as a good, right decision. Instead, it's similar to the one in Unforgiven; in Unforgiven he chooses to return to his evil ways; here, he chooses to sacrifice his soul for another's benefit.
I'm sick of arguing this point with people (not you, as you didn't take this position) who refuse to see what's RIGHT THERE in the movie and need everything spoon-fed to them.
The only boxing film I want to see is the upcoming "Cinderella Man" starring Russell Crowe and Renee Zellweiger (spelling?).
