I'm having a weirdly hard time understanding this one. If by "fail" you mean "get bad endings", those are kind of speckled throughout the game so far, and will continue to be. There also endings (so far just one) that aren't strictly "bad", but do end the game. In any case, bad endings always loop you back to the decision you made before getting them, and "early" endings will do the same if you choose the option to.
As the game progresses, there will be things that trigger certain events during the final chapter that will alter the ending sequences, but that's very far in the future.
