The fact that these people are intensely aware of moral truth even as they seem unable to resist violating its law while and this is important making no excuses for themselves, renders the movie particularly powerful. Ultimately, it is the fact that the two protagonists are devoted to one another beyond life that makes their story so hauntingly beautiful. This is not pure romanticism, if that term refers to the glorification of morally oblivious feeling. The movie portrays passion in all its terrifying, dangerous reality. It states too that moral laws are violated at a price and that price is very high indeed.
Innocent people end up getting hurt.
But it does not go on to conclude that feeling is therefore to be denied, shackled, obliterated. The answer would have to be, it seems to me, essentially yes. And yet. . . . That answer, paradoxically enough, must also be yes, truly yes. But ultimately, this is no didactic morality play but a work of art.
