I still don't think Sundering is murder. It's never been made a fact in-game or outside the game and would just make Venat's action seem like bad writing. She sundered to save new life, if Sundering was murder, then it doesn't make sense for her to kill everybody including the new children to save the new children. I think you're better off focusing other points because your argument is focused on something that's not even set in the baseline lore
