If absolutely any theist I know tells me that it is okay to murder an innocent child because their parents belong to a region that treated your people badly, and because someone said that God said to, I would cut that monster out of my life faster than I typed this comment.
Again, it isn’t a moral framework to say “whatever God says to do is good.” That’s just obedience. It says nothing about the morality of any given action, and provides us with no framework on which to build our moral code. It’s just saying “that guy said he wants these kids dead, so the right thing to do is kill these kids.” Absolutely hideous.
