This meme originates from a climactic scene in "Star Wars: Episode III – Revenge of the Sith," where Obi-Wan Kenobi, played by Ewan McGregor, confronts his former apprentice, Anakin Skywalker, on the volcanic planet of Mustafar. As Anakin succumbs to the dark side, Obi-Wan, heartbroken and furious, delivers the line, "You were supposed to destroy them, not join them!" This moment captures the essence of betrayal and shattered trust, making it a goldmine for meme creators who love to exaggerate everyday disappointments.
