Let me guess, she eventually gets her power taken away by him in order to become God Emperor Doom so he can create Battleworld and swing his big d**k around to show how awesome he is. Because, god forbid a female character exist without needing to prop up another male character’s story.
I mean, with how Gamora and Natasha were offed ultimately to forward Thanos and Clint’s respective storylines, I have very little faith in the Russo Brothers handling of Wanda without making her an accessory, just having her suffer and/or getting her power/agency taken away by the main villain.
Idk, I don't see Natasha as being killed to "forward Clint's story", she was a hero who made a sacrifice to stop Thanos. It gave Clint an emotional moment, yes, as it did for the rest of the OG Avengers, but its a moment that happens to characters all the time in fiction. It cheapens her sacrifice to say she just did to forward the men's stories.
With Wanda, it is also a common thing that happens in these types of stories, a character with power gets used/consumed by the villain who seeks power. Would it make it better if he does the same to others (eg Franklin, Beyonder, Kang, etc) as he's very likely to try to do? It'll be icky if there's a romance there like in the comics, but without it I don't see it as her "propping up" a male character, just being a source of power he wants for himself, as villains are wont to do. Was she just propping up Agatha's story in Wandavision, or was she being charmed and coerced by someone who wanted the power she had?
Gamora, though, agreed. They did her dirty.
I still find it preposterous that Thanos "loved" her, because they didn't set it up properly at all. All we'd heard prior to Infinity War was that she, like her siblings, was subjected to battling her siblings, with torture and body modifications in store for the loser. There was nothing to indicate he truly loved her.
Every time I see that scene I'm like, "bulls***, you can't lie to the Soul Stone, Thanos!" If he was to truly sacrifice that which he loved, he'd have to throw his own ego off that cliff. It'd be like Trump having to sacrifice the thing he truly loved... "well s**t"
