The MCU released their first movie: Iron Man, in 2008, thresholding the Avenger Age, where multiple superheroes summon and together fight against not only terrorists on the earth but also the outsiders. Throughout nearly 30 movies and hundred battles, the Avenger teams always keep abreast and support each other., but there are still casualties and death that happened to them.
Most of their sacrifice occurred in the incident of the Infinity War and the End Game, which give rise to a sense of remorse in the movie.
