A turning point for me when leaving the JWs was watching online the stoning to death of an African woman. It was the most barbaric thing I have ever seen. Crowds of people were screaming at her, throwing all manner and size of rocks at her. She was cut and bleeding, would struggle to her feet and collapse again to the ground. Small rocks hitting her head had stunned her so she deliriously would attempt to stand. It took many minutes for her to finally be unable to lift herself, as people contined to pelt her with more rocks. I have since looked for that video but can no longer find it.
What it showed is that the Mosaic Law was written in a time of barbarians. Stoning, slavery, the treatment of women and animal sacrifice were all inhumane. No educated country would pass such a laws in our more enlightened times. Any person that complains about modern society is unaware of how much we have progressed. The Old Testament was a product of its times and fortunately the Greeks improved culture enough that by the time of the New Testament the writers were somewhat less offensive.
