If there is no sin - then how can we "chose the right"? With that sentence right there you disproved your point. But beyond that - there was sin. Satan sinned when he rebelled against God. 1/3 of the hosts of heaven sinned when they followed Satan. Sin requires the ability to chose, and in the pre-mortal life we definitely had the ability to chose. Yes, at it's core Satan's plan would take away our free agency - but his actual plan was to get God's glory for himself. But everything I said was in reference to taking away our agency - which I actually said directly in the post you seem to have not read.

But yes - I am saying that this kid wants to be free from the consequences of sin. That is EXACTLY what I am saying, because that is EXACTLY what this kid is saying. He's just dressing it up with other words. He said - I want to be able to do what I want without getting kicked off the football team. In other words - sin without consequences.
