Yes, and this does not imply, in any way, that God caused it, or that Adam didn't freely choose it.
You're getting that argument from that kooky libertarian (ex?)Freeper who used to capitalize all the nouns in his posts. What was his name again?
His name was orthodox presbyterian. OP never believed that God authored sin. In short, I’d say he believes the sin was planned by God, BUT that the humans did make their own choices.
