[ Part of her does want to punish him. That tiny bit of her that still clings onto all of her sins wants to make sure he is weighed down just like she is. But, she dismisses it every time. Sephiroth is different. She never knew him, beyond the one meeting, but it's enough for her to tell he really is different in Mandalus.
