Death in the MCU
As in the comics, nobody (that matters) stays dead in the Marvel Cinematic Universe. Captain America didn't die in The First Avenger, and the same thing happened with his pal Bucky, who then became the Winter Soldier. Nick Fury faked his death. Loki couldn’t even manage to stay dead; he was revived for The Avengers.
Only Quicksilver bit the bullet. However, his introduction was so brief that audiences really hadn't had time to connect with him.
In the movies, the absence of death (the ultimate peril, so to speak) sets the stakes very low. But in Guardians of the Galaxy: Vol. 2, Yondu's death/sacrifice might usher in a new era in which we can't say who will make it out to appear in the next film. We feel that this uncertainty would benefit the shared universe.
