Gotta disagree with ya there.He's not *clinically* "sick".He's amoral.There's a difference.
We may be just debating degrees. Delusion can start out small and snow ball and we may be seeing some of that here. But then again I see the Bush Derangement Syndrome and now the Sarah Derangement Syndrome as possible diagnostically delusional so go figure.
I am sure we are each right in our own viewing and assessment just separated by, as I said, degrees and possible listing in the DSM IV, in which I am sure they do not yet have a picture of Letterman nor Garofolo pictures under delusion. Time however may change this.
Where I think you are absolutely correct is if Letterman where to ‘straighten out’ morally the end of the delusions and ‘right and socially acceptable action’ may begin. On this I absolutely agree.
