Earlier I was imagining Star Wars as a neighbourhood tabletop roleplay game. In it Palpatine is actually this really kind old man who plays this extremely evil character that has everyone going home and wondering about old man Sheev. It all got started when Sheev came over to offer everyone cookies when they were just getting started, and someone thought it would be funny to invite him over to join in on their game.
He is sometimes visited by his son Maul who joins in for a couple sessions, and who plays a character who is also dramatically evil. Then you have Palpatine’s character beat down Maul’s character and everyone’s just sitting at the table in stunned silence. Basically their personalities are a complete flip of their actual selves. I just find that juxtaposition funny.
