Not for what you did. You tried to bring eternal nigth. Douing so would have killed many, plant and beast alike. It was a crime, there's no question about that..
No, I feel sorry because of what you endured after.
1000 yeard alone. Few have ever deserved a fate such as that. Separated from a sister who loved you. Who's heart was probably broken by having to do this to you. I cannot imagine what it must have been like for both of you during all this, nor do I wish to experience it.
Hopefully, now that things are peaceful btween you two, you can regain the happiness that was lost.
