There seems to be a major misconception that just because the Torah says you CAN do something that you SHOULD do something. If this really true, then every Orthodox man should venture to get married, divorce his wife, and then remarry her. Sounds stupid, right? But if you say that Biblical permission is sanction, that happens to be the logical conclusion.
The Torah begins with a commandment that if while in the midst of war a man is overtaken with passion for a woman, he can take her as a wife. However, according to the flow of the verses a downward spiral begins, where he ends up with a wife he will end up hating and ultimately a screwed-up child. Not the biggest endorsement for taking female captives, but very enlightening for understanding the Jewish concept of free choice.
People believe that if G-d is truly doing good, everything He does should make your life easier and better. Better true, but not always easier. Better is being given the ability to make choices in your life and life with the consequences. That’s being an adult. G-d wants us to be adults, and not to live in a dependent-type relationship. The Torah is not written with all of the answers; it’s written to give people the tools how to answer them.
