Funnily enough, out of modern superhero movies, I think MCU got me to empathize with a villain the most. It was Thanos, who had a legitimate reason for reducing the population of the universe and didn't even want to discriminate.
I've grown bored with the MCU and haven't seen any of the newest films, but Infinity War was actually great.
Hey, the Corleones took care of their own. Traitors however...
