A lot of people [theists in particular] argue that people are basically good. That when given the choice to do the right thing, they will. In 1962 - 1963 Stanley Milgram ran an experiment where random laypeople were place in positions where they could choose to harm or not to harm people. But there was a catch... they were being told to continue no matter what under the direction of an authority. Delivering painful electric shocks to another "subject" on the other end [actually an actor PRETENDING to recieve shocks, as none were actually being delivered] when the subject answered a question wrong. With each wrong answer the power of the shock went up, until it went into a range that was potentially lethal. The experiment's results shocked the scientific community. As it turned out, over TWO THIRDS of the subjects would go ALL THE WAY TO THE LETHAL END!! - Without knowing that they werent actually delivering shocks! Replicating this experiment [while controlling ethical guidelines] in the 21st century, the results are striking. Once again, the vast majority of people from all backrounds and personalities will deliver the shocks until the end despite the screams of the other subject. And this... is a powerful set of evidence that theists are very wrong when they say that "People Can CHOOSE to be Moral." - Perhaps... it is the opposite? It seems that in certain situations, the vast majority of people are willing to commit attrocities if they are being assured by authority [such in the real world could be the church? or The Nazis?] that they take no responsibility for the outcome!
