Everyone follow along with the voices in your heads as you read this script segment from the end of Episode VI:
Luke, help me take this mask off.
But you'll die.
Nothing... can stop that now.
Before the prequels were released, that last line would have been given no extra thought. But now, understanding how Anakin fell to the dark side, it seems like it could be more meaningful than that. His fall was entirely rooted in his inability to accept the inevitability of death, and specifically his frustration that even he was powerless to stop those he loved from dying. Now in his last moments, it looks like he can finally admit the truth that he fought his whole life.
So my question is, do we know if this line is intentionally deep, or am I reading too far into it? From what I understand, Lucas had the full story somewhat figured out by the time Ep VI came around, so it seems possible that it was written that way on purpose.
