While I don't disagree, "that's the point" is not a great argument. It's simply an explanation.

If someone is caught in the act of cheating, it doesn't help if they say "he just wanted some action on the side!"

The problem is the cheating, the reason for cheating doesn't make it acceptable.

You have effectively just stated that "oh don't worry he meant to cheat."
