'King of the Dead'

Osiris was murdered by his own brother, Seth. If I was murdered by my brother, ain't no tellin' what would happen to him. Osiris's body was dismembered, and scattered, but Isis, his wife/sister reunited his limbs. MAGIC! Osiris then became King and Judge of the Underworld. I think that Seth was very jealous because Osiris got Isis and he didn't. It seems to me like Osiris should have been the God of gettin girls, and Seth should have been God of the Underworld.
