If only religious leaders could be trusted, then maybe there wouldn't be so many problems. They have perverted any truth that the Bible may have.
A good, all-loving god would not destroy his creations no matter how they act. He tells parents to love their children unconditionally. I say 'you first, God.'
Religion is good, as it controls the people that don't have the intelligence to make worthwhile decisions. However, it could be debated as to whether this makes up for the atrocities committed by these people.
Looking at the Bible, it would seem that God is just a more highly evolved human.
