Because if God forced everyone to be "good", no one would actually be good, theyd be soulless NPCs or mindless animals. If you dont think Free Will is a good explanation, perhaps you dont understand Free Will. Free Will is the choice presented to all Rational beings, whether men or angels, to either choose God as their ultimate Good, or to reject Him. God is no tyrant, He wants to give Himself freely to everyone, not to force Himself on people. Evil is an unfortunate possibility due to Free Will, and the more people reject God, the more evil they get. The wickedness of the jews is the result of good men refusing to carry out the mission given to them by God and put a stop to them, not the fault of God Himself or some evidence Creation is flawed.
