I like it much more than "Empathy" - which seems for me kinda far-fetched - the symbolism in it is really great. Also the way You write about it is quite similar... to way I explain different Element for her. Element, which - like Twilight - has double meaning (Twilight Element represents not only Magic, but also Friendship... which fits really well because... well Friendship is Magic...).

I mean Element of Forgiveness/Redemption. Well actually there isn't perfect translation of this into english. The forgiveness part is easy, this second... well there isn't proper translation of Polish term "nawrócenie" into English. Literally it would be "conversion", but in English this term seems to not have any moral value actually, meaning just changing faith, or maybe even not necesserily faith, but still could be into good or wrong. In Polish... although it is connected with changing faith this isn't the essence of the term, neither must be used in that context. It mainly mean turning from evil into good. Leaving behind sins, bad deeds and starting new life as a better person. And that perfectly fits Sunset! It's not only what happened to her but also something in which she helped other (like Twilight, but some other EG villian to, even if not alone... but hey, Twilight great deeds also wasn't all just her, right?). Because redemption is... kinda similar in meaning - though as far as i understand the word is not exactly the same - I usually go with it when talking about it in English.

Also Redemption and Forgiveness, are stronly connected when You think about it a little more. They are kinda like two sides of the same coin, therefore making perfect complet for next double meaning Element... and there couldn't actually better idea for the Seventh, last Element (due to number symbolism I think Seven Elements is the perfect number of them).

And I don't think redemption is "limiting" her. We sohouldn't forget, that meaning of the Element isn't neccessery just this what we think at the first time when hearing that word. Elements seem to usually go beyond it's simple meaning. It is most visibly with laughter - which is actually far beyond than just make other ponies/people laugh or smile. This is in some way "core" of the Element, its most promiment manifestation but it don't limits only for that.



Though I must admit, Guidance is something that arguably fit Sunset even better. Just it doesn't seem fit the Elements so well, isn't such perfect fulfilment of the Elements (similar feeling I have about Empathy or Healing... Hope... well actually too, but it's the closest to fitting from this four) - but maybe just for me. It's my idea after all so I can be a little not objective.
