I wish they'd have stuck with it/her. WORD. I understand why she died, but I don't think she necessarily had to, and in different hands than Kripke et. al, she could have been such a fascinating, complicated character, especially after Lucifer's rising. I mean, there's a whole epic redemption cycle there just waiting to play out! The inner war between her faith & her lord, and her love/humanity, in fact almost parallel to Castiel's - this niggling, growing disenchantment with everything she once believed in, and now isn't really sure about. Like, is your faith your religion or your love? Is it the establishment (Lucifer/the angels), the heirarchy & trappings, or is it that core of belief, and what happens when the love and sacrifice in that core is all for a God that fails you? What happens when your God isn't good enough?

And why does she believe? What's the essence of the demon religion? Is it Lucifer - or is something else, something older and perhaps stranger, and less defined?

ARGH. SO MANY QUESTIONS. I really feel like the writers took the easy way out when they killed her off. Because she wasn't done. Not by a long shot. If you're familiar with Avatar: the Last Airbender, killing Ruby was like if the writers of AtLA decided to have Zuko freeze to death at the North Pole. So much story that never happened.
