It was better when they were dealing with Magneto.
Now, Wanda is a batshit-crazy genocidal. Well, but she is an Avenger. Then nothing will happen to her. Nothing.
The Avengers are murderers, genocidal, fascists, and they've put the entire planet at risk several times. Indeed, they have already destroyed whole planets.
The Avengers are worse than Red Skull, Thanos and Dr. Doom.
But the Avengers can do anything. They are Avengers, after all.
And so, I repeat:
Maybe the Avengers should arrest Jean Grey when she returns. After all, she's the Phoenix, right? She has already destroyed an entire planet.
And Spider-Man and Iron Fist are the Phoenix experts. So, yeah, okay.
Well, the Avengers should protect the planet. So, first, they will attack the school, then, arrest them all. Basically, all the X-Men.
Let's see:
Captain America: "We'll have to take Jean Grey into custody anyway."
Kitty Pryde and the X-Men: "Okay, sure. We don't want to be called 'terrorist' or EvilPryde. Okay, Cap, you can take her."
So, Jean Grey must be arrested or maybe killed. Maybe Logan will kill her, or Hank, or Wanda, or Clint Barton, or Carol Danvers, or Steve Rogers. They are Avengers, after all. So, nothing will happen to them. Nothing.
