In the movie “Avengers: Infinity War,” Dr. Stephen Strange, also known as Doctor Strange, is one of the many superheroes who fight against the villain Thanos, who is on a quest to collect the six Infinity Stones and use them to wipe out half of all life in the universe. In the course of the battle, Doctor Strange uses the Time Stone to view millions of possible futures, in an attempt to find the one path that leads to victory against Thanos. He eventually determines that there is only one possible outcome in which the heroes can succeed, and he willingly surrenders the Time Stone to Thanos in exchange for the safety of Tony Stark (Iron Man).

In the follow-up movie, “Avengers: Endgame,” Doctor Strange is one of the many heroes who are resurrected after the Avengers use the Quantum Realm to travel back in time and collect the Infinity Stones before Thanos can use them. In the final battle against Thanos, Doctor Strange wields the power of the Sorcerer Supreme to help defeat the villain and restore the lives of those who were lost in the previous film.
It is worth noting that Doctor Strange is a complex character with a history of making morally questionable decisions in the comics. In the MCU, he has been portrayed as a somewhat arrogant and self-centered character, at least in the beginning of his origin story. However, over the course of his appearances in various films, he has shown a willingness to put aside his ego and work with others for the greater good.
As for whether he is now evil or not, it is possible that future MCU projects could explore this idea. The upcoming film “Doctor Strange in the Multiverse of Madness” has been described as a “horror movie,” and it is expected to delve into the concept of alternate dimensions and realities. It is possible that this film could introduce a version of Doctor Strange from an alternate universe who is more villainous than the one we have seen so far. However, until more information is released, it is impossible to say for certain whether Doctor Strange will be portrayed as evil in any upcoming films or shows.
While it is possible that future MCU projects could explore the idea of a more villainous Doctor Strange, it is currently impossible to say for certain whether he will be portrayed as evil in any upcoming films or shows.
