I didn’t believe this a few years ago, but Yuval Noah Harari changed my opinion with his book Sapiens.
Is morality a monopoly of religion?
Religions and morality are often disjoint, simply due to Euthyphro's dilemma and how that plays out in practice. Divine command theory externalizes responsibility for behavior and thus promotes and excuses immoral action (meaning many religion's resolution to the dilemma puts them into a commitment to behaving immorally).
You can't be evil if people believe you define what evil means.
This way omicient, omnipotent God can still be most moral being in existence while allowing babies to die of cancer.
