One response to the problem of evil has been to say that God grants us freedom and evil is a result of sin.
The problem with this is the one of why He gives us freedom to begin with. It’s like if the cops ignored a murderer in the name of freedom. Imagine if FDR and Churchill had chosen to ignore Hitler in the name of freedom. And the idea of original sin doesn’t explain why He punishes people for the sins of their ancestors. Likewise, why He would give us freedom and then forbid us to do certain things hasn’t been explained.
So it appears that nothing they say in this argument is of any help.
