The Thanatos Gambit is what happens when a character deliberately manipulates the circumstances of their death to their own profit. It could be to ensure that they get as comfy (or stylish) an exit as possible, but most often, it's used to deliver one last "Screw you" to their archnemesis. A character who is Secretly Dying is especially likely to employ one of these.
