Apparently it was justice. The Bible clearly said they were wicked.
Animals and children were wicked? I've no use for people who simply buy whatever they're told if it comes from a recognized source of authority. Rape, slavery, selling children, treating women as the spoils of war, all of these things are in the Bible as being acceptable behavior. Along with those pleasant things are prohibitions against mixing fibers in clothing, associating with a woman having her period, cutting portions of the head hair, etc. The things you accept as Commandments from God are just as weird as the Mormon sacred, secret underwear.
I don't recognize your references to feces.
Ezekiel 4:10-17 Bake bread with human feces and eat it among your enemies.
Malachi 2:1-3 Smearing feces on people's faces.
Try to step outside of your own ethnocentric ideas to see that there are different ways to look at the world and your way is not the only right way.
Try to think with the brain that God gave you, would you accept your sister or your Mother to be taken as one of the spoils of war? Do you think that rape is alright? Commanding people to eat bread baked with their own feces? Child sexual abuse? Which one of these "ethnocentric" ideas do you embrace by the grace of your worship of Jesus? I'm sorry, Who, but slavery and genocide are not just casual ethnocentric ideas that one can cast away at a whim on the sayso of some baseless religious or mythical god-figure. Jesus said that the two most important commandments in the Bible were to love God and to love thy neighbor as thyself, no place did He say that slavery and rape were acceptable. The Bible paints God as a monster who commited terrible crimes against humanity, I think that's blasphemy, God didn't do that stuff, that's the kind of thing that people do and by attributing it to God they can make it acceptable behavior for themselves too.
I myself do not completely understand asking a father to sacrifice his son but since the father didn't seem to have any problem with it I guess by his standards he didn't think it was that bad. Perhaps both the father and his God understood that the sacrifice would never happen.
If a Father today didn't have a problem with a disembodied voice telling him to take his son up onto a mountain and forcing him to help build an altar and sacrificing him to some "god" we would say that person was insane. Children's Services would take the children from that home and put them in protective custody. The Father would go to jail or to a mental hospital.
But for the sake of the argument, let's say that Father and God knew that the sacrifice was never going to take place--WHAT ABOUT THE SON? What does it do to a child that goes through that kind experience right up to being tied on the altar with his Father's knife at his throat? If that isn't child abuse then you have a very different view of child care than I do. Would you like to read about a child that had things like that done to her? Get the book RABBIT HOWLS, which tells the true story of a girl who was abused in hideous ways.
When some god-figure is credited with the most heinous/atrocious/revolting and foul/filthy/perverted sick behavior, it disgusts me that there is always some simpering sycophant willing to be the apologist for the "god" and claim that the "godly" actions were just or right or holy--we just don't understand and need to take it on faith.
How a rational human being gets from the Sermon on the Mount to accepting genocide, rape, scatological abuse, and coprophagy is beyond me.
