Mario is a generally a well liked video game character. He's been around for a very long time, and practically everyone around the world knows his name. They also know that he's the quintessential good guy. Mario is constantly saving Princess Peach from the clutches of villains. But what if he decided not to do that one day? What if Mario became the bad guy? Maybe he'd have her locked in a dungeon, to prevent anyone from stealing her away. Perhaps Mario would be awful to Toad or Yoshi, rather than being friends with them. A bad Mario would be a terrifying thing to consider.
