"Still Alive" Diagnosis

I dug up an interesting "Still Alive" diagnosis for portal that postulates a split personality for GLaDOS and that all the stuff she said was true if you take this into account. I like it. A lot of the offhand comments from GLaDOS support a fragmented personality if viewed externally rather than accepting that GLaDOS is toying with you.

If this diagnosis is true though, that all GLaDOS comments are legitimate, then the last few lines of the song have a more sinister undertone. Maybe the "personality cleansing" you did may not have been quite as successful as GLaDOS hoped:

Portal - Song Lyrics:
...
And believe me I am still alive
I’m doing science and I’m still alive
I feel fantastic and I’m still alive
And while you’re dying I’ll be still alive
And when you’re dead I will be still alive
...
