If You Hate Me, Then Kill Me

Laconic: A character is angrily berating another, then the latter dares the former to act on their feelings.

Usually the result is that the character to whom the dare is made is so taken aback that they're unable to act.

I feel bad adding another trope to the workshop when I have two unfinished pages, but I've always been better at coming up with tropes than polishing them.

Live Action Television

 * House. In the episode "The Tyrant", the team has a brutal African dictator named Dibala as a patient.  While they wrestle with the moral implications of treating such a man, Cameron suggests to Dibala's colonel that Dibala may be permanently brain damaged, possibly hoping that the colonel will decide to kill him rather than risk having someone with impaired judgement in command of his country.  Dibala finds out about this, and when Cameron is about to give him an injection, he dares her to put an air bubble in his IV.  "If you want me dead, then pull the trigger. It is not so easy when you have to do it yourself."

Movies: Live Action

 * In Sarafina (and possibly the stage musical its adapted from), the titular character yells at a local policeman after she witnesses him beating a student activist in her class. He responds by offering her his club "You be the policeman. You beat me, ok?  Come on, go ahead.  Those kids burning the schools?  You let them go free.  Those kids driving the stores out of business?  You let them go free too.  Those mobs running around the streets, looting and killing?  Let them go free.  Be the policeman.  I'm the bad man.  Ok, beat me."

Webcomics

 * In Quantum Vibe the crew meets Jesus Hernandez, a vigilante pirate fighting to end slavery in the Jovian system. Nicole objects to him taking it upon himself to act as judge, jury, and executioner of everyone on board the ships he captures.  He then turns the tables by asking Nicole to judge him, promising to turn himself in to whatever authority she deems appropriate.
