Should I Save His Life Again? (Early Morning Rain, Gordon Lightfoot)

"I keep saving your life, and what good has it done? It's just gonna keep happening again and again, maybe that's the point, eh? Maybe it's a test."
 - Desmond, Catch-22

I think one reason the scene between Sayid and Desmond in The Last Recruit was so powerful was that Desmond had been similarly tempted to sacrifice Charlie for the sake of a reunion with Penny. Here I imagine Desmond's own crisis of conscience to the tune of Peter Paul and Mary's Early Morning Rain.

Should I Save His Life Again?

Should I save his life again when it’s time for him to die?
If the arrow finds his throat, can I look him in the eye?
For the sake of true love, must I sacrifice my friend
And be saddled with a guilt he can’t comprehend?

Brother Campbell told the tale of Abraham giving up his son.
If I let his death unfold, who will laud what I have done?
If it’s some great cosmic test, then will God reward my zeal,
Or will I be condemned for a dirty devil’s deal?

What is right and what is wrong? (What is right and what is wrong?)
Is there any way to know? (Is there any way to know?)
Do I interfere with fate or do I let Charlie go?
If I had him make the call, would he choose suicide?
If I knew the choice was his, would my own remorse subside?

With the moment drawing near, still the cryptic questions taunt.
Is it selfish to proceed? Is this what my love would want?
If I step aside, then I’ll be sure to find Pen,
But my conscience won’t comply, so I’ll save his life again.
No, my conscience won’t comply, so I’ll save his life again.
