ThGod became Son to provide that sacrifice for sins that God did not ask of old Abraham nor would his son's death accomplish anything. 'My justice requires I step up to the plate'. Hallelujah ☺️
So then, it's just theater. Nothing was really sacrificed. God decided he couldn't forgive without the shedding of blood so he could come be the hero. Dude is insecure as can be. First he creates people just to praise him, now he sets up a scenario by which he gets to save those people and be even more the hero. Wow.
It's also not very good justice. If two human lives cost perfection and God's favor, and then only one life was sacrificed to balance it out, God isn't very good at math or restitution. He's also not very good at justice because he kind of had a ringer out there playing the game. If I was Satan I'd be pissed. God is a cheater and didn't play fair at all.
Then again, your belief seems to come down to "might makes right", so I guess fairness goes out the window.
