This is what always bothered me about this scene. Rogue can never be normal. She'll always be an outcast. Storm was considered godlike in her homeland. She could use her powers for good, and could always maintain them. They never bothered her. They never affected her life for the worse. Rogue just wants a solution for her pain, while Storm feels threatened about her greatest attribute being taken from her. It's not her decision whether it's good for Rogue or not, it's Rogue's.
