The thing about the endings, Bad, Good/Normal and True they have to follow the logic inside the plot and here we have a huge problem.
I believe the inclusion of Chadrito was the way Fujino found to correct course, because the endings he had planned would not work anymore since he did several small and 2 big changes (plot twists) in the story the council reveal and Asuna memory manipulation.
I think the endings will be based on how or if Kirito will confront Asuna and Inoda, and how Fujino will present the truth to Kirito in the story, he's teasing right now, Liz told him the truth this only made Kirito go into chad mode, everything is tied to the revelation and in Kirito's reaction, that will be climax of the main story and will define the climax for the rest of subplots, Council, Girls/harem, Goddess/Admin.
The bad ending is a new thing that Fujino is not even sure to include just thinking about, but the way the plot develop is almost impossible for Fujino not to do it, otherwise the Chadirito would not be a thing now, because he was included as plot device/new character just for that purpose.
