When the brothers were conversing king Shahrayar said to his brother king Shahzaman:

Brother, you were fortunate in  killing your           wife and her lover, who gave you good reason      to feel troubled, careworn, and ill. In my                opinion, what happened to you has never            happened to anyone else. By God, I had been      in your place, I would have killed a hundred        or even a thousand women.

I dont believe that someone can just kill because of adultery. However it is unpredictable when a person is covered with strong negative emotions. King Shahzaman must blocked out when he sliced up the lover and his wife and then threw them out the balcony. It’s very hard to imagine what will be the reaction when you caught someone red handed. It’s really a matter of flight or fight.

King Shahrayar is showing of to his brother that this will never happened to him because if it did he will kill them all. His wife will not going to dare to do it or even think about it because she knows her place. No one should assume they know everything that is going on in his/her life. In addition if you believe you are doing great be humble

I can see in this excerpt the foreshadowing of king Shahrayar. He had it so bad. His wife was having an orgy in his palace while he is gone. It’s more than an orgy because it has role playing, heterogeneous and homogeneous sexual intercourse, mix racial and mix social class.
