Agatha told Wanda that there were no take backs, what she gonna do hold a town hall and be like, my bad?
Nah, the best way to protect them and anyone else is to learn wtf you really are and how to control the shyt, that's what she went to go do.
But the consequences from this will come from the worlds reaction to what happened to the people in Westview. There will be interviews from the townspeople detailing how torturous it was and people will fear Wanda more than the already do. She could have zero to do with Mutants and still set precedent for the xenophobia that will be coming behind the exposure of people being born different with powers they can't necessarily control. It will be like Civil War and the Sokovia accords, cept the stakes will be much much higher and reminiscent of the OG comic run.
People been worried about how much sense it would make for mutants to be hated when the public is cool with the Avengers, shyt like the hex is why.
