Let us not forget that while Serj is an artist, he is also a very politically aware person and almost always reflects that in some way. He likes to share the truth, or at least his interpretation of it in a manner that even the most oblivious person can still find enjoyment from it.
In all of Serj's creations, I've never understood him to write folk music without some underlying issue in there. With all the things in the world, I would hardly think that a suicide pact went wrong would be the main message in this song.
Now, this might seem a bit of a stretch, however with his background, and his beliefs; I would assume this song has to do with the betrayal of the government towards its people and how they still blindly love and follow it (note how she continually returned after him killing her multiple times); the ignorance and blind patriotism being willfully exploited by the government if you will.
This act of betrayal leads to the downfall of our government as we know it; because as I take it, from the video, they don't seem to understand the importance of their people.
He's shown that he believes society and civilization as we know it is over; I just take this song to be a prelude to that, showing his belief in how it happened.
Of course, I could be reading into it far too much. : p
