1001 Arabian Nights

After reading the history of 1001 Arabian Nights, I have a better understanding of how they came about. It's been interesting reading them. There is such a wide range between many of the stories. Many have blatant racism, and of course the infidelity.
One story, The Tale of The Three Apples, was a little surprising. The beginning of the story was a little misleading to where the story was going. A poor fisherman pulled a trunk from the river in which a body had been placed. There were 3 men who confessed to killing her, but it was her husband who was guilty. The rest of the story explains why. His wife was ailing and wanted an apple, but there were no apples where they lived so he traveled far and brought her back 3 apples. When he returned to her she was very ill and bed ridden. A couple days later one of their sons took one of the apples. The apple was taken from him while he was playing by a black slave. He claimed it was given to him by his mistress, who he claims is the mans wife. The man believed the story and slayed his wife by cutting her up in pieces and putting her the trunk.
It's really annoying that these men will believe these stories about their wives infidelity, but will not check to make sure what the truth really is. Are they afraid to talk to their wives? What makes them slay them without a question? After the man slayed his wife he found out that their son did take the apple and that the black slave stole the apple from their son. The black slave was slayed for the killing of the woman. Maybe in at least one of the stories they will believe the woman before slaying her.
