Historical events in the real world implies that Mario could've had the choice to kill baby Hitler or stop any other monstrosity and he feels it's more important to give Newton his fucking apple back, better yet why doesn't he also go back and just kill Bowser too. Like yeah you'd never get the present that you wanted and Mario wouldn't have a purpose but he's been getting fucked over by this turtle for nearly 40 years now. Too busy surfing to do anything meaningful in his life or contribute to society in the slightest. 1/10
