"I am not arguing for a moment that he should not have been killed.
Of course he should have been killed."

Yes, of course the speaker there wasn't responding to the question of a supposed moral case involving "the lesser of two evils" - I was.

The "moral case" Lighter put forward based on "the lesser of two evils", was founded on the premise that Bin Laden would be a more dangerous figure alive than dead - others however - such as the speaker in that clip, argue differently. I think it's a valid point of view.
