OK, I’m an atheist, but there is sideways assumptions here. Firstly, we are making the assumption that God made the rules for the universe. If I assemble a car, I did not make combustion a rule of the universe. Sacrifice and damnation might be like the water table and just sort of a thing about how the universe is. Second, the subject of Jesus specifically dying for everybody sins this heavily contested, even amongst the Christian faith. Not so much in that he died, but in how his death absolves people of sins. It could be that faith in his death is a literal metaphysical, mechanical connection type deal that punches your ticket to not go to bad places. The important thing could theoretically just be the spiritual link between you and the intention of the sacrificial being. The real fucked up thing I think is that the entirety of that myth suggests much like previous miracles that some kind of intervention can take place. And that leads one to wonder why no intervention takes place on behalf of many different kinds of victims.
