In Egyptian mythology, Set is known for killing his father, Osiris. Set's actions stem from jealousy and a desire for power, as he sought to usurp the throne of Egypt. After murdering Osiris, Set dismembered him and scattered his body parts across the land, which eventually led to the resurrection of Osiris through the efforts of his wife, Isis. This myth illustrates themes of betrayal, death, and rebirth, which are central to Egyptian beliefs about the afterlife.
