Imagining that in Altered Fate Reader either didn't manage to follow Belos through the portal or arrived too late when he was going to kill Luz, 1) would Belos regret killing Luz and 2) what would he have done to the body? Bury it? Or keep it preserved until he returned to the Human Realm so he could give her a burial/give it back to her parents?
No, he doesn't regret killing her. He just regrets the thought of the deed and not the deed itself because HE didn't want to do it. No, that had to be done because of what the WITCHES did. By no means is this his fault. He only failed in the sense he couldn't talk sense into her in the previous attempt because of Eda and Lilith. This was a mercy kill in his eyes.
IF he doesn't use it for a Grimwalker, he'll preserve it and take care of it when he got back to the human realm. He doesn't know who her parents are so he'll do it in an unmarked grave in town somewhere.
