Braga's words, unedited:
Seven Of Nine learns, as she begins to explore her human emotions, that she can’t experience them. There’s a Borg chip inside her that will kill her if she tries to do so. First of all, that’s kind of an interesting ‘rape victim’ analogy or whatever you want to call it, about a damaged woman who can’t get past what happened to her, but I also always saw it as a crucial episode that would set up the finale.
“This was a woman who knew she was neither here nor there. She couldn’t go back to the Borg, nor would she want to, but she could never be fully human, so she was doomed. And I wanted to have her sacrifice herself to get her shipmates home.
I don't see anything there about "dying doing a human thing" and any idea of redemption ... just doom and gloom and "you can't go home again."
