Those people, tsk... Mafuyu's on her last fort standing on her "final" decision, she made it clear to them that she doesn't need help anymore so its natural that she snaps at them for insisting and getting in her way. She wants to die. She doesn't care what everyone feels because "she will die anyway". I know the feeling because I've seen someone snap at me the same way or worse than what Mafuyu did here (but I let her go so yes two days later she jumped off a footbridge.) Yet all of it (even Ena's grudge) calmed down because in the end they succeeded and Mafuyu came back.
