4. Maude Flanders is a sociopath.
According to a fan theory that first appeared on the No Homersfansite, Maude Flanders was a sociopath. The poster, Diversity Pumpkin, points to several scenes that suggest Maude hated Ned and wanted to kill her husband before her death in season 11. On several occasions—be it during a bear attack, imminent comet, or rooftop danger—Maude either left Ned for dead or showed no concern for him. After she passes away, the imprint on her bed is facing away from Ned, meaning that she spent every night facing away from her husband.
