The game doesn’t need to give you a way out. But for the moment to be impactful you do have to manipulate the player in to believing that they made a decision and are thus culpable for their actions. Players have to feel ownership of what they did to feel shame, remorse, and horror. If they had no choice except “press x to do warcrimes” or turning off the game they’ll press x and grumble about being railroaded by the story.
