The defense is that there's more going on then she's evil. Acknowledging that she's a super-hero who is a normal person who happens to get in over her head with powers corrupting her, like this hasn't happened to any X-men, isn't telling anyone to ignore what she did. You may as well just write Jean off forever if you started during the Dark Pheonix saga. This is the actual reason why Jean to died in the Dark Phoenix storyline.

At a trial I'd love to see this bought up when Cyclops is on the stand. He's such a hypocrite when it comes to Wanda and so is Rogue.I told Chris that the ending proposed in his plot didn’t work. It wasn’t workable with the characters, and in fact was a totally lame cop-out, storywise. I demanded a different ending. Chris–enraged–asked me just what that might be. I suggested that Phoenix be sent to some super-security interstellar prison as punishment for her crimes. Chris said that the X-Men would never stop trying to rescue (?!) her and that the story would become a loop. I said that then he should come up with an ending.
I wasn’t privy to Chris and John’s conversations that night, but whatever.
The next morning, Chris stormed into my office and said that there was only one answer–they’d have to kill Phoenix. I said fine.
I don’t think he expected me to say that, since killing characters just wasn’t done in those days. Chris waffled a bit, but then I became insistent! She’s dying. That’s it.
If you want to condemn super-heroes for being evil when they get corrupted or turning to the dark side we'll have to create an entire thread over the X-men since that's a long list. But the problem isn't that, it's that those characters you like and Wanda's an "outsider" to the X-men and worse, an Avenger.
I'm curious what your response would be reading Onslaught where all the main super-hero teams are friends.
