Freddy Fazbear, the main antagonist in the series, except for the 3rd game... is he good or bad? People are always saying, OF COURSE HES BAD HE EATS YOUR FACE OFF IN THE 1ST GAME. What if he's being forced to do it. Forced by somebody like, oh I dunno... The Puppet. Why do I think this? Let me give some backstory. You know how Freddy didn't move in the 1st and 2nd night? Because he was reluctant to hurt you. Now this is debatable that he was studying your moves and actions, therefore making him evil. But I have evidence to back me up. You know in the 2nd game, how when you beat the first 2 nights, it shows Freddy's head looking at Bonnie and Chica? Those would link up with the first 2 nights in the first game. But when you beat the 3rd night, the puppet is in your face. The 3rd night is the first night Freddy is active. This means the puppet may be forcing him to kill you, but Bonnie and Chica already tried to do what they're told. But this brings up another question, Why is the puppet forcing him to kill you in the first place? Because he wants to give the gift of life to you. Its like being generous in a dark way.
Hope this theory is pretty straight foreword. Baiiii.
