In A Simple Paradox Concerning God’s Goodness he writes:
Has God committed morally wrong actions? If God is the almighty creator of the universe, then there are countless instances where there was an event that God was either directly or indirectly causally responsible for that we would ordinarily identify as morally wrong. Consider the class of actions or omissions that we would identify as morally wrong if a moral agent had been present and had committed them or allowed them to happen. A person drowns by herself near a dock on a lake where a life vest sits on the dock. If a person had been standing next to the life vest and saw her drowning in the lake, but refrained from tossing the life vest to her, we would think of that failure to act as morally abhorrent. There are countless other events like these where it does not appear that God did what we would ordinarily have identified as the morally obligatory act. Therefore, it would appear that God has committed (or by omission allowed to happen) countless morally wrong events.
