Man, this is good. It's refreshing to see her finally realize that she fucked up HARD. It's also sad though - her mentality is basically that of a child that doesn't really understand death, and now that child found out that her selfish actions have consequences and that she killed the person who loved her the most. Don't get me wrong, she deserves all the pain, it's just sad that this all had to happen. The selfish girl gets to live in with mental anguish at the realization of what she's done, the selfless but naive spirit died; and even though Bertia and the prince will probably be ok, they have to deal with the cleanup and possible regret at the death of the light spirit (because while readers may not care, someone in that situation would likely feel something).
