Ill list every MCU movie in which the villain is killed.
SPOILERS HERE. CONTINUE AT YOUR OWN RISK.
Iron Man Captain America* (putting an asterisks here because Red Skull is referred to as dead but appears much later. Or just count all the hydra cap Mercs if you wanna be anal about it) Hulk Iron Man 2 Avengers (Chitari) Iron Man 3 Thor The Dark World Guardians of the Galaxy Age of Ultron Civil War (crossbones) Dr Strange Guardians 2 Thor Ragnarok Black Panther Avengers Infinity War Avengers Endgame Spider-Man Far from Home. Yes I counted all suicides by heros. CE gonna split hairs here but that phrasing alone by heroes should be all the argument necessary.
