Here we see a difference between a believer and an unbeliever. An unbeliever (like you two) will set himself as an authority above God, and will question and judge God at every step. A believer will trust and obey God. Abraham is uniformly praised in Scripture for his faith in God and his willingness to obey whatever God commanded. He did the right thing in obeying God.
Even if I was a believer, I would still prefer to spend an eternity in hell with the good guy instead of the monster you worship.
Just wondering if you could bring yourself to try to see Abraham's obedience the way believers have seen it for many millennia: as a noble act of faith in the the one true trustworthy good God?
I started out as a believer Faith, indoctrinated from a young age. I never took it literally though and never saw killing children as something good. You see, I think almost all humans are born with some degrees of empathy. It was religion that took yours away.
