Whatever the violation.  Doesn't matter.  The question was, "Would Christ ever say 'Good riddance.'"?  Answer:  Yes.  My citation proved that.  As did my point that Jesus preached fire and brimstone.  Now, you may want to argue that having sex with dad's wife was a special case.  But then don;t tell me you can't imagine Jesus saying "Good riddance."  Just be honest and say you forgot about that example or didn;t know about it.  But, in fact, the situation Paul discussed in Corinthians wasn;t the only example.  Remember all those goats?  When Jesus finds a goat at the Last Judgment, Whoosh, and off he goes, into the everlasting "fars of hale."  And you don't have to be a Billy Graham to believe that.  Just a God lovin', God fearin' Christian.
