For the sake of this thread, let's suppose some form of Abraham's God is really real and the theistic religion has the facts right. I'm gonna go with Christianity, as that's what I'm most familiar with.
Christians say that you need God's forgiveness because we are filthy sinners. Luckily, Jesus died so His Father would not look at us without disgust.
But I ask you... Do you forgive Jesus and His Father? I don't.
Look at all the suffering. Look at the genocides that the Father ordered the Israelites to carry out in Cannan! He openly ordered murder of people who broke a seemingly artificial moral law book. He flooded the earth and all the animals in it. Reading the Bible, it seems to me that God puts us through unnecessary misery, as He brags about His omnipotence.
So... no! I don't forgive God. I balk at the idea that Yahweh is demanding that I seek forgiveness from Him! My mother held her faith that Jesus would cure her cancer all the way to the very end... Do I forgive Jesus for allowing me to watch my mother die as a babe? No! Though, some would argue it was good because it built my character...
So, hypothetically, if an Abrahamic God is real, do you forgive Him?
