"So why don't you do me a favor and pull the trigger?! Pull the trigger! Do it! Do it, motherf-----r!"
— Rick Sanchez demonstrates his suicidal tendencies when he orders Morty to shoot him.
Characters who have either attempted to take their own lives or succeeded in taking their own lives, or have been overly eager in the face of death. There can be several different reasons for this, including remorse, "honor", avoiding a worse fate, their lives are terrible, despair, sacrificing oneself for their greater cause/allies, the hero being an insane nihilist, hoping they'll take the villains down with them, or even a redeeming sacrifice and other possible reasons.
