Yes this testimony seems definitely biased. While Almighty God has granted us the freedom to make choices of our own volition, having that freedom doesn't mean we are always wise. 30 years ago I had a friend who was convinced he was wiser than Jehovah's organization. So he left. And after many horrible experiences over a span of ten years, one near fatal, he decided to return to Jehovah's house. He came to realize that "like a blind man I was not aware of the danger that was in front of me each day". Truth is not something we can merely wish away.
