nscansr - Of course the god of xtian theism can do anything that is LOGICALLY POSSIBLE. Nobody is arguing otherwise.
However your god specifically advocates for evil actions such as slavery, kidnap, rape and genocide. Jesus told his disciples to literally abandon their wives and children to follow him.
But more damningly is the evil that god does himself. He made a world that is perfectly designed to maximise suffering. No creature dies peacefully in its bed. All fall victim to disease, starvation, exposure or predation. That includes all of our human ancestors. The entire history of life on earth is one of carnage.
Then there are the natural disasters that are entirely of god's making. Tens of thousands of innocent children drowned in a tsunami that god could have prevented without any impact on free will.
How do you defend your god from the accusation that he is a moral monster?
