Well, it's not just that. At all. At a surface glance it seems that is what it is about, it's actually a complex story about love and responsibility and how you would personally react in that situation. We have all been tempted, right? Poe said it best; '...the spirit of perverseness. Of this spirit philosophy takes no account. Yet I am not more sure that my soul lives, than I am that perverseness is one of the primitive impulses of the human heart -- one of the indivisible primary faculties, or sentiments, which give direction to the character of Man. Who has not, a hundred times, found himself committing a vile or a silly action, for no other reason than because he knows he should not? Have we not a perpetual inclination, in the teeth of our best judgment, to violate that which is Law, merely because we understand it to be such?' It's also a wickedly good puzzle which becomes ever-increasingly hard and complex. And that is only scratching the surface. If you really, and I mean REALLY go hard, you start coming up with stories about sumerian mythology, especially with the inclusion of Ishtar, the goddess of fertility, love, war, and sex. And dumuzid, the shepard. And even fucking Astaroth which is mentioned several times in demonology, alongside beezlebub. And I'm really honestly only JUST scratching the surface.
