Although Earth's Mightiest Heroes managed to best Thanos and reverse the Decimation in Avengers: Endgame, they were only able to do so after a long five years had passed. However, what if they'd never had to in the first place? A new theory suggests Doctor Strange could have actually prevented the event from ever happening in the first place, but didn't for a very good reason.

In Avengers: Infinity War, we saw Doctor Strange looking at the various possible futures, finding only one in which Earth's Mightiest Heroes might managed to defeat the Mad Titan. However, he might have actually looked farther and seen some event that required him to make sure the Snap did indeed happen in order to achieve the best possible results.
