I am still somewhat confused by this logic. And Ive been through a whole rung of religions.

Salvation from what? The hell God created to torture sinners? At the very best God could create a reality in which those who sin, just live and exist in a state of bliss away from him. God by choice does not do this despite having the power to and is forced to turn to human judicial systems in order to maintain order.

Humanity is called to separate the sins from the sinners. Okay fair. But God isn't?

Why does God require sacrifice especially blood sacrifice from his creations? Why are all of these arbitary rules in existence to begin with? Its almost as though God operates under the constraints of a system imposed on him rather than one he creates himself. And if he wasn't he would have a lot to answer for.
