God graciously gave us free will. The point is that He didn't and doesn't want us to become those mindless zombies you were talking about. He wants us to make the right choice of our own free will.
As for compassion for the non-believers... I weep for those who do not believe. Literally. As that old song goes... "Some of those souls are so dear to me/ I can't bear to think what their fate will be/ and because of who You are/ the compassion that's You/ Oh Lord this must tear Your great Heart in two..." I fully and firmly believe this.
Do you think it's mean or wrong of God not to just let everybody in to Heaven, even though they're sinners? Truthfully, none of us deserve to go to Heaven... because of the original sin of Adam and Eve plus all the sins we each commit during our lifetimes. God was wonderful and gracious to send us His Son to save ALL of us... God wants everyone to be with Him in Heaven. That's why He sent His Son Jesus Christ to save each and every one of us. Now it's our turn. Do we choose to be with Him or not? To believe in Him or not? It's now OUR choice of our own free will whether or not we go to Heaven.
John 14:6.
