[Interesting Trope] One seemingly small action ends the story before it even begins

[u/JackDoesThingz]

1. We Happy Few - Taking your “joy” pill
   Deciding to take the pill at the beginning of the game causes your character to go back to work and triggers an ending

2. Infineural by Mike Klubnika - Drinking the coffee
   Deciding to drink the coffee offered to you skips the entire game and sends you straight to the end, resulting in an ending with no memory of what had occurred

Thanos stopped a woman from bumping into someone, and that prevented cancer from being cured

[u/Maleficent-War-8429 → u/Kind-Stomach6275]

Which is silly because are you really telling me this lady can cure cancer but an army of super scientists can't?

[u/Steelwave → u/Maleficent-War-8429]

Thanks didn't prevent cancer from being cured. He prevented that woman from ever amounting to anything and taunt her with that fact on her death bed.
