I feel you are taking this to take away any meaning the text actually has.
And it would be traditionally Moses who wrote this down.
I think it is more you who has a modern obsession, if I am to be frank.
I may botch some of this story up, but Abraham was the son of an idol maker. He one day smashed all his father’s idols, and his father returned home, saying, “Who did this?”
And Abraham replied, saying, “They fought amongst themselves and have caused this”
And his father replied, “What?! Idols do not move,”
“Then why do you worship them?”
Indeed, Abraham had realized that if you worshipped a thing on Earth, it easy defeated by another. If one were to worship fire, it would be put out by water. In this manner, he was able to shame the ruler of the land.
But he followed God, and was made a friend with God, and made a pact with Him.
Abraham was promised that he would have those of his seed numbered incredibly, and that his descendents would inherit the land.
However, in his old age, he had not a son by his wife. However, miraculously, she was able to birth a son in her old age.
Now the next part is important
God promised to him that his son would be the heir to him.
Then, God asked Abraham to sacrifice this child of his that he had promised Abraham would be the heir.
Abraham, as the child of an idol maker, knew of the sacrificing of children to the idols. But this was no idol, but the LORD that he was to sacrifice to.
He does not lie, and keeps His covenants.
So Abraham knew not what was to happen, but trusted in God and carried out His Command, even though he understood not how this would fulfill His promise to him.
So Abraham went in faith to do the thing, but then an angel of the LORD stopped him, and behold, a ram (which is a male SHEEP) was provided by the power of the LORD to be a sacrifice. And Abraham sacrificed him.
This serves multiple purposes. One, it is saying YHWH is NOT like those idols, and does not need human sacrifice. Two, it teaches us the importance of faithfulness and carrying out the commands of the LORD even when we don’t understand them. Three, it is a clear type of Christ, probably in multiple ways. The male sheep provided by God was what was sacrificed. In this, the one whose seed would bring forth Israel was spared. God does not require our sacrifice, but provides His own. And it is also possibly a type of the Resurrection.
What do you have against this story?
