Beerus’s Death

"No..." Whis watched Beerus 'burn' in He-El's hand and reached out, wanting to stop it, but he could not intervene. As the assistant to a God of Destruction, an Angel could not interfere with or act against a God of Destruction. His role was to assist, educate, and help the God of Destruction; he could even offer suggestions, but he absolutely could not act in a way that influenced the God of Destruction. Angels had no duty to protect Gods of Destruction.
