You really should look at what a film IS instead of what you want it to be to make your point. Million Dollar Baby would be propaganda if the Eastwood character were pro-euthenasia, or if he were against it and then thought it was good after having a part in it. It doesn't; it says he is condemned by his personal religion for doing that. Show me the Nazi propaganda that tells its followers "If you do this you are condemning your soul to damnation."
By your logic the people who liked The Passion are pro-crucifixion. I mean, it shows the crucifixion as a good thing, something willingly entered into, right?
For those ready to scream and shout: I am NOT saying that those who liked The Passion are pro-crucifixion--note the first words "By your logic".
It's a take-off on Mark Twain. Remember Huck Finn's "Then I'll go to hell!" when he takes the side of the runaway slave, Jim. Twain's point was that the character Huck takes the moral high ground by rejecting the (in this case, racial) conventions of his society. The idea became something of a cliche, and it is on that cliche that "Million Dollar Baby" rests.
