Makes you think
This meme is knee-slappingly hilarious, but it also makes you think. Why on Earth don't any of the Marvel superheroes die of natural causes or in the hands of a villain? We only see them reach their end when they sacrifice themselves to save their Avenger buddies. Boo!
For instance, in Guardians of the Galaxy, Yondo, the blue man with the spiky red mohawk, sacrifices his life to save Star-Lord. Black Widow gives her life up in exchange for the Soul Stone. Hawkeye's life is spared when Quicksilver swallows a barrage of bullets. No one suffers from an ulcer, premature dementia, or gets squashed by rubble.
