It appears to me that Jehovah allows His self aware creations to find their own way, to make their own decisions. That He does not micro-manage all aspects of life. Satan's chose to leave Him, one third of His angels chose to leave Him plus Adam and Eve. All were perfect yet were allowed to choose their own way as poorly as it was. So bad judgment not imperfection is the real problem. While imperfection compounds the problem, perfection doesn't eliminate it. We all have ability to choose what direction we will go in. Ancient Israel's leaders were given a direction by God to go in, yet they regularly choose another direction. God's present day people have had the same choice facing them, are they/we, from the GB on down making the right choices. Realize too the choices we make always effect others. If we are the GB and we make poor choices the whole Earth wide congregation will suffer.
I am not mad at God for free will...I am grateful to Him for it.
