Comics and movies are different mediums, for one. Also, if that’s the case, you would know Thanos with the Gauntlet overpowered all the cosmic gods, timekeepers, the living tribunal, etc. All of them. So this is already comic inaccurate.
And you'd know that there are no absolutes.

Very curious on how this plays out for him! He’s definitely had some highs and lows so I see this as the start of his redemption arc.
