People always have a choice in what they believe in, and it's usually social engineering and misplaced anger that draw people away from God. After what some people have been through, and are going through, with wars, famine, disease and other atrocities, then I really can understand why they will turn away from God; I've had the experience myself, during my darkest days of depression and loss and God really is the only one to vent your sorrow and anger at.
Thing is, the more educated I've become, since leaving the education system, the more I leaned towards God...strange, I know, but it's been a process of discovery and a journey towards something far greater than myself.
Man's inhumanity to Man is the greatest atrocity in this world; it's past, present and future. God is not responsible for Man's actions, however still, He will bear the brunt of society's blame.
For example, the war-torn country of Yemen; we see the appeals for donations on TV, and we willingly help because the images we see are heartbreaking. However...is this God's fault? Who is bombing the living crap out of Yemen, to subdue and bully it into submission? The answer really isn't surprising. A supposed 'ally' of Britain, no less.
