Dead MCU Characters

A lot of characters – mostly villains, which is appropriate in this instance – have died in the Marvel Cinematic Universe to date. However, given the reality-warping power that Thanos will be wielding in the Avengers: Infinity War movies, could the Mad Titan bring them back to fight in his corner?
Some of the dead villains are quite personal to the heroes of the MCU – Obadiah Stane was Tony Stark’s mentor, Kurse killed Thor’s mother, Ronan killed Drax’s family etc – so raising them from the dead could give Thanos a psychological advantage over them (while a zombie Quicksilver would also traumatise Scarlet Witch significantly and Ultron might turn out to be part of Thanos’ plan after all).
Dead never truly means dead in the world of comic book movies, so don’t be surprised to see several deceased characters returning in the biggest event in the MCU.
