I mean, we came from within a hair's breadth of annihilating all human life on the planet during the cold war, for pete's sake. Now that didn't come to pass, but if you look at all the atrocities that did happen during the history of humanity...

Atrocities in general are a point worth considering. They make it clear that, even given the existence of God, there's a lot of agency being given to the human race; it's up to us as a race to not mess up totally, and to face the consequences of the actions of others.
