Kill Me Moment

You see that pistol over there?

Was everything, absolutely EVERYTHING, you worked for worth nothing? Did the princess you were trying to save for, like, the fortieth time get murdered by The Villain right before you? Did you finally achieve a goal only to have it do much, much, MUCH more bad than good? Well, you might be headed in the direction of having a Kill Me Moment.

This is when someone realizes or sees that their great amount of work and effort put into something was completely voided or undone by something, such as somebody else coming along and making it look as if it never happened or they've been trying to stay in perfect condition for a driver's license picture, but then right as the cameraman takes the shot, some clumsy moron comes along and spills coffee all over them. This might make them wish they were never born and decide that Quit Mode is better than continuing to live.
