Sandbox / Narrative Catharsis In Universe

• Characters.A Song Of Ice And Fire House Martell: Catharsis Factor: In-Universe. Burning him and his entire army with dragonfire must have felt cathartic to the Targaryens, who had only experienced headaches and humilliations fighting the Dornish previously.
• Characters.Batman The Character: Pothole in quote, not sure if it fits.
• Characters.Codex Equus The Changeling Courts Spring Court: Catharsis Factor: Chrysalis' defeats and eventual exile to the Winter Court was this to her. She celebrated by piling up Chrysalis' private belongings in her fortress after she was dethroned and burning it all with an unhinged grin on her face, and then going to Chrysalis' room in Avalon Palace and wrecking everything inside with a sledgehammer she borrowed from her sister Queen Odonata, laughing maniacally all the while. And having both instances photographed/filmed by her siblings and subordinates for the memories.
• Characters.Game Of Thrones Theatre Troupe: Catharsis Factor: In-Universe. Since Arya missed out on killing the real Joffrey, seeing an adaptation of him die gave a huge smile on her face. The Adaptational Comic Relief probably also helped.
• CodeGeassThePreparedRebellion.Tropes A To I: Catharsis Factor: A curious In-Universe Invoked example happens when Zero told the upper echelon of the Black Knights about Clovis' private think-tank. Lelouch knew that learning about the atrocities committed in Code-R would make them livid, so he preprogrammed a Knightmare training scenario into their simulators where they could destroy Clovis' G-1 Mobile Base over and over again to vent off their anger. He even included transmissions of the late Viceroy begging for mercy to enhance the experience.
