There is certainly collateral damage in every war. I don't remember anything about Bush or FDR giving specific instructions to target and kill both man and woman, child and infant, ox and sheep, camel and donkey.’ ”
My point is that the world is at war. I don't think anyone wants babies dead except the abortion industry. When there is a war, innocent people will die. There is no way around that.
Another example of what you are talking about is when God asked Abraham to kill his son as a sacrifice. On the surface, that looks insane. However, if you take the story in context to what was going on during that time, it starts to make sense. During that time it was common for people to sacrifice their children to pagan gods like Molech, so the request would have not been as shocking to Abraham as it is to us today. And as we see in the story, Abraham did not want to do it. He loved his son. And I think on some level Abraham either believed God would stop him, which he did, or would raise his son back up to life based on the promises God made to him concerning him.
So God stopped him, but why ask in the first place? It was to show him and the world that the God of the Bible does no sacrifice innocent blood like the pagan gods because he was different. It sent a message and it gave us the most courageous examples of faith in the Bible.
As for mandates to kill during the Canaanite conquests to which you refer, this is yet another example of faith being on trial. What was God thinking? Was there a better way? These are questions all people of faith struggle with, just as Jacob struggled with God physically. In fact, Israel, which Jacob was latter named after his struggle with God, means to wrestle with God.
I have my own conjectures about this, but I still have faith in God's judgement. If they had not done it, would it had led to more death and suffering later on, for example.
But we can only conjecture, as where God knows all.
Another example would be the Great Flood. Did God save humanity by killing them all off? You would say no, but those of faith would tend to think this way
At the end of the day, only God knows.
I keep thinking of a scene from Schindler's List as Russians roll into a POW concentration camp in Nazi Germany. They simply take a look around and see the evil depravity, and just start hanging people without uttering a word. No trial, no rehabilitation, no, these people just needed to be dealt with yesterday. This is how I view the people during the Great Flood
