Some people don't understand it, but I have always loved Paul Young. He just gave off mysterious vibes from the start, but he truly was a misunderstood hero. Everything he did was for his family, he killed Martha Huber because of the letter she sent which led to Mary Alice's death. Paul ends up getting framed for Felicia Tillman's murder and goes to jail, but makes one of the most iconic returns in season 7. He gets out of jail and spends all his time getting revenge on Wisteria Lane and buys multiple houses on the street so that he can build a Halfway House LOL. He then confesses to killing Martha Huber and goes to jail as a hero, while his rival Felicia dies <3 An amazing story arc.
