The world as we know it is a winding path of events and probabilities. Everything changes with each decision we make, which causes endless ripples, and you end up with a swarming armada of butterflies. Each one is there flapping their tiny, little wings with every move you make, sometimes without you even realizing it's happening. And then sometimes the thing you do is simply killing off a main character, thereby changing everything forever. That is precisely the type of stuff that we are talking about here. The various deleted scenes exorcized from the bodies and souls of movies and TV shows that, if left in as originally planned, would have changed their stories and characters forever.
From beloved television series to horrible science fiction movies to slightly less horrible science fiction movies, here are a few deleted scenes that – if they stayed had canon – would've changed the story forever.
