I find the human sacrifice in 2 Samuel 21 to be uniquely different then in most of the Old Testament
Usually those who commit human sacrifice are punished and or said to have done wrong
In this case it seems that human sacrifice was rewarded
One might argue it is not human sacrifice but the execution of a wrong doer but it is actually an execution of the relatives of a wrong doer who might not have committed the crime
I am opposed to human sacrifice and not endorsing it
"Could it be that Saul’s descendants who were hanged had followed in the wicked paths of many from the “house of Saul” and deserved the death penalty? Yes. Thus, it is once again impossible to use this passage to “prove” that God accepted human sacrifice."

Apologist said this in response to a claim that there is human sacrifice in 1 Samuel 21
But they failed to show with certainty whether or not it was a death penalty for wicked deeds
