Sir, I invite you to take a few steps backward and look at an even bigger picture. Free will does not contradict the sovereinty of God, it makes it more glorious, mysterious, and wonderful.
You're imagination of the greatness of God will be significantly enlarged when you understand that God does indeed give freewill to men and angels and yet, even with all the variables this presents, maintains absolute control over the affairs of men and conclude them to His predetermined purpose to the glory of His name.
