I was wondering the same thing recently, even though my time is much more limited right now.

For some reason, the thing that came to mind this morning was a quote I've always found profoundly scary from Oscar Wilde's An Ideal Husband: "I remember having read somewhere, in some strange book, that when the gods wish to punish us they answer our prayers."

There's so much wish fulfillment in FF (and definitely in JAFF), which isn't necessarily wrong. But what about when we desire things that are ultimately destructive, perhaps not only for ourselves but others as well? What about the darker side of the heart? Would we truly be happy, if we achieved a good end through bad/dishonorable means? Or would it poison that happiness, leaving it stillborn at achievement?
