For those who do not believe in the concept of god, viewing the stories in the bible from the human perspective make no sense. To those who believe in God, the stories have to be looked at from God's point of view, to the best it can be discerned. I was once an atheist, so I understand these differing points of view.
Jesus had free will, he chose to make the sacrifice he did. Could God just forgive mankind their sins? Apparently not. Apparently God is limited in that He can't violate His justice (which supersedes law). The wages of sin is death, and that price had to be paid.
There are many instances where people are recorded in the Bible questioning God's actions and motivations. They rarely receive an answer, nor are they usually punished for questioning.
No surprise if you don't think God exists, comforting if you do.
I've always wondered why atheists are often so hostile to religion, especially Christianity. Given that almost all progressive political thought is a direct descendant of Jesus' Golden Rule, and the Beatitudes, you'd think you'd cut Him some slack. Yeah, His teachings have been misused by man for their own selfish needs, but men do that with every belief structure--even progressivism.
