There's a neutral ending too.
The name of the game is "Dishonored". I decided to delete all saved files and start over, not just because I want to get the good ending, but because I rushed the gameplay. I think you can have a neutral or bad ending easily but you need skill to get to the good ending. I'll finish the game in good ending first and get to the other endings later. Then I'll delete the bad ending save file so the story will hold the good ending lol
