To be fair, it's an action that will come at a price. Amanda would surely pay any personal price to save Kalilah, but the price may not just be personal.
For me this question is very simple. The Shiplords are under the impression that someday we will embrace their philosophy of non-being, that willing self-sacrifice is a thing to be honored rather than a tragedy and a crime to be prevented:
I am dark and I am danger
Trials without end
But when time comes to greet me
You will call me
friend."
But for me, there are few things that cause as much internal revulsion and horror as people who think that death is a gift.
[x] Save: Dive into the heart of a building storm, through Shiplord weapons and a fire born of a soul of Destruction, to save the one who summons it. Amanda
will survive this, and for an action so deeply within her Focus, she has a good chance of saving her friend. But there will be consequences.
I know that this has essentially been Kalilah's overriding goal since the First Battle of Sol and the Week of Sorrows; nonetheless, I simply can't countenance letting her do it. "'The mark of the immature man is that he wants to die nobly for a cause, while the mark of the mature man is that he wants to live humbly for one.'" Kalilah has spent the past seventy years living an adolescent's dream of going out in a blaze of glory; now it will be our responsibility to teach her to grow up and find life's other virtues.
This will be good for us in the long run. If we reject, here and now, the notion that sacrifice is a noble and worthy goal, it will give us a good standing on the moral high ground when we inevitably have to confront the Shiplords over the same philosophical difference. In fact, in that future battleground, something I doubt we'll see fully realized until near the end of Secret Wars or beyond, I hope to enlist a rehabilitated Kalilah on the front lines, blazing a trail with the same focused determination she has shown in both the Second and Third Battles of Sol, but I suspect that's going to be a long, hard road to find from where we are now and where we will find ourselves in the near future.
