Dear Nell,
The point is not that Lee or anyone else doesn't need to repent of sins. The point is that you said because he cursed some therefore he never blessed any, or because he didn't repent (to your satisfaction) any blessing he might have rendered is invalidated. My point is that either point is an extreme and incorrect view.
This issue is not how Lee will be judged. We don't know that. The issue is you seem to be saying he did nothing pleasing to God.
What, exactly, don't you buy?
