Regarding the scriptures...
In much of the Bible, especially the Old Testament, there are laws that command that people be killed for absurd reasons such as working on the Sabbath, being gay, cursing your parents, or not being a virgin on your wedding night.
In addition to these crazy and immoral laws, there are plenty of examples of God’s irrationality by his direct killing of many people for reasons that defy any rational explanation such as killing children who make fun of bald people, and the killing of a man who tried to keep the ark of God from falling during transport.
There are also countless examples of mass murders commanded by God, including the murder of women, infants, and children.
