The spread of advice seems to cover everything from hanging, through public humiliation to "aw diddums" counselling approach. Whatcha gonna do?
Personally, I'd go for the VERY carefully researched background and a "created" occasion to skewer the chap, but very slowly, so that he can fully savour the awfulness of his situation as it dawns on him. Did he appear to be a stupid person? In which case all that effort might be wasted. You've had 4 pages of advice - I say again - whatcha gonna do?
