Why didn't he just keep her sane when he came back? Under the hands of a good writers, a Jean Loring redemption arc would have been great and would have created possibilities for a 'The Atom' spin-off title, it would have been cool to see what really drove Jean over the edge, having her try to return to normal life, making amends with Ralph, repairing her relationship with Ray and keeping villains from influencing her. It would have been much better than turning her into a one note villain.
