The notion that God is all knowing frees humanity of any blame for original sin, since God knew that we would make bad choices with our free will before He gave it to us. Either God intentionally created flawed creatures in a flawed universe or He tried His best to create perfect creatures in a perfect universe. If the first is true, then God is a sadistic jerk. If the second is true, God isn't all powerful. Either way, this is not a deity worthy of worship, amirite?
