The upcoming Doctor Strange in the Multiverse of Madness appears to be framing the Scarlet Witch as one of the film’s antagonists, but this decision would be a huge mistake for the future of the MCU. The Doctor Strange sequel looks set to be a mind-bending journey through the multiverse, as Steven Strange is faced with the consequences of his actions in Spider-Man: No Way Home. Doctor Strange's multiverse spell opening the gateway between universes and bringing a host of characters from other Marvel properties into the MCU has no doubt rattled the good doctor, with Strange appealing to Wanda Maximoff for more information regarding the multiverse in Doctor Strange 2.
The MCU's Phase 4 has already seen wholesale character development for Wanda Maximoff. The end of Avengers: Endgame leaves Wanda without her romantic partner, Vision, with WandaVision going on to explore how she dealt with her grief after being unable to save the man she loves. WandaVision as a series fundamentally questioned whether Wanda should be viewed as a hero or villain, with her entrapment of the citizens of Westview blurring the line between the two moral camps. In the WandaVision finale, Wanda also takes on the mantle of the Scarlet Witch and begins learning the spells from Phase 4's Darkhold to discover the true extent of her powers.
Wanda’s journey in the MCU towards understanding both her powers and herself reached its peak in WandaVision, and the character’s potentially villainous intentions in Doctor Strange in the Multiverse of Madness risk betraying her story arc up to this point. While it is true that Wanda has blurred the line between hero and villain before and has subsequently become one of the MCU’s most powerful characters, it would nevertheless be wrong for the franchise to change her motives entirely. The Doctor Strange sequel, however, appears to be doing just that. -Screen Rant
