Has anyone ever played with this Trope by seemingly playing it completely annoyingly straight right up until the hero doesn't escape and is in fact killed horribly by the elaborate death trap?

This occurs at least once in every book of Anthoney Horrowitzes' Alex Rider series. Sometimes even twice in the same book.

Should the Cocodrile's example from One Piece count or is an aversion of the trope. The thing is that after having impaled someone in the chest with a hook and buried him in quicksand, one could reasonably assume is death.
