Following the scene on Titan where Quill starts beating Thanos, this is the second moment in 'Avengers: Infinity War' where Thanos could have been defeated before performing his snap. Strange said he saw all possible futures and that there was only one out of 14 million in which the Avengers were going to defeat Thanos. I have always wondered how that was possible because there were these two moments in 'Infinity War' when there really was the possibility of taking the gauntlet off Thanos or killing him. At first I thought it had to be a plot hole because if Quill doesn't lose it or Thor goes for the head or chops Thanos' arm off, there is no way Thanos is still performing the snap. But what Marvel were really trying to tell is that there was not a single future where Quill keeps his cool or Thor takes immediately goes for the kill. In other words, Quill was always going to lose it when learning about Gamora's death and Thor was always going to try kill Thanos slowly and make him suffer. Of course, this is very questionable from Marvel, but it is what they wanted us to think.
