Wanda obviously needs to be incarcerated with a ton of therapy. Think the Raft combined with a top-tier mental institution.As far as justice is concerned . . . . what exactly needs to happen to Wanda? Who has the authority and power to arrest, try, and punish her for her crimes against the people of Westview? What would be the appropriate punishment? What about the significant mitigating circumstances of her apparent disassociative personality and not being fully aware of what she was doing? Could Wanda somehow offer restitution to the people of Westview on her own? What would that look like? Granted, these are all questions to be answered by the writers of WandaVision, or the follow-up in later MCU shows . . . . but this sort of thing is a problem in comic-book stories in general. How do you bring our modern sense of justice to super-powered beings?
Imagine a more mundane parallel . . . a woman hurts others while acting out in extreme grief, trauma, and a dissassociative personality break, but minus the super-powers. What would be appropriate? Jail? Counseling? Some sort of mental institution? We don't handle these sorts of things in the real world all that well, add super-powers to the mix and I can see why the writers punted the issue other than Wanda's walk-of-shame through the townsfolk towards the end.
In real life, people with mental illness who commit crimes a fraction as bad as Wanda's aren't just let go. They get institutionalized, where their freedoms are curtailed so that the damage they inflict can be contained. It's worth noting that, at the end, she's still not trying to get therapy...she's off trying to become more powerful. What happens the next time she feels bad?
Now, who could bring her in? No idea. My issue is that apparently that's a non-issue. No one seems to be thinking that anything needs to be done (hence, Rambeau's catastrophically dumb line). I appreciate the punt metaphor you used, but...in football we punt when the opposing team has stopped us from what we are trying to accomplish. Who was stopping the writers here? In other words, why did they write themselves into a situation where this happens and all logical questions about accountability get swept under the rug?
Justice is definitely a theme in the MCU. It's not hugely different from our own: people need to be accountable for their actions.
I mean, unless you're an Avenger? Maybe Zemo was right after all.
