If you have a mother, you would understand. Mothers only want to protect their children, not hurt them. They believe that they know best like Kaguya. Idk if she really meant what she said (She said she hates them). Kaguya was pissed. Everyone has a soft side and I think Kaguya's heart is broken. She needs to see that having all that chakra corrupted her and that her sons meant well, because they were afraid.
