Didn't God know that this movie was going to be produced? Why didn't He stop it, if it is so horrible?
Hitler?
Osama?
Stupid questions?
But foolish and unlearned questions avoid, knowing that they do gender strifes. - 2 Timothy 2:23
Yes, of course He knew. He also knew you would ask that question. :)
Why didn't He stop it, if it is so horrible?
For the same reason He didn't stop Adam from disobeying Him in the garden, and for all the other sins of man since then. We either follow Him or follow our own desires. One brings peace, joy and a contentment in any circumstance that there are no words to describe. The other produces the opposite. It has always been that way.
If God could be tempted to intervene based upon the behaviors of men (who would be manipulated by the evil one), God would be reactive, not the Sovereign of the Universe. Also, should this reactive posture rule the reality in which you dwell, you would not have a free will in any sense.
The divinity of Jesus is an essential quality in bringing Salavation to we humas because God has told us that no one goes to where God is lest He come to make a way to Himself.
Since you asked the question and you knew you wouldn't accept any answer that actually comes from the Bible, why didn't you make fair disclosure when you asked the question?
Thus is your taunting foolish.
Things can and will occur in your life that are manifestly evil, so that people can have free will in this life. Having free will, they choose whether to do good or to do evil to other people, even some bad things they didn't intend for evil but ended up hurting others. Followers of Christ's teachings believe that, ultimately, every minute of your life and every word out of your mouth is witnessed and judged by God, and will determine the degree of your enjoyment of eternity.
No natural human can approach perfection of his own efforts; therefore, our sins (offenses against others, rationalizations and lies) are more or less constant. Even if we try really hard, some sins are done in our name, such as those done by the effects of actions in our workplaces, governments and other group structures which we support by our taxes or participation.
Fortunately, God sent a manifestation of himself in human form into this world as Jesus of Nazareth, who after himself sent the Holy Spirit to instruct us in what God wants of us and to guide us when we are in doubt or are tempted to do wrong. Persons who believe that this is a possibility are able to perceive the workings of the Spirit. Those who deny the very possibility, quite obviously, cannot believe nor even hear the promptings of the scriptures or the Holy Spirit.
Christ's death on the cross was an atonement to God for our sinful natures, and he will stand up for us when we are judged by God, provided that we make a conscious choice to follow him and his teachings, which we must read in the scriptures, not in pop fiction, in order to know. God (who, being all-knowing and all-powerful, can read hearts and minds) knows who belongs to him by the convictions of their hearts, by their regret and repentance for their sins, their efforts to avoid further sin and their willingness to endure the persecutions of unbelievers, to the death if need be.
And, being all-knowing, he knows who will not do these things. Many skeptics do believe that if they do not believe in God, they will simply cease to exist when they die, or that they will go to an entertaining place of their own invention. It's a crap shoot as to whether either of these beliefs are any more true than the Christian scriptural beliefs that they will be judged, and some will ascend to live eternally in paradise, while others will not; or, worse, will be punished for their harmful acts.
You have the free will to believe as you wish. The burden of proof remains yours, as well.
If you would like to try a simple test, vow to yourself that you will go one entire 24-hour day in which you interact with people normally, on the job or in your community, without lying. Be honest within yourself. See how easy or how hard it is to avoid telling an untruth for just one day of your life.
