Yah yah yah so many implications about what "sin" really is! I love it. I love that Cain is wandering the earth forever. I've never read a fic where that was the case... but, now that I think of it, why not? I mean, Genesis claims that no one can KILL Cain but isn't it juicier if Cain can't die at all? Nice one ;)

I liked it...very cool

Oh some demon angel's gonna get his ass kicked! And this god person sounds really immature. I would think that Gabriel would hate being called "Gabe," don't abridge it. Other than that, you portrayed Cain as as a bad boy motorcycle loner. Nice job, this guys' pretty cool.
