You're supposed to feel bad about someone who was pushed to her mental and emotional limit and did something she deeply regrets, yeah. That's what compassion for the vulnerable is about. This is like a rite of passage for X-men. When you found out what Rogue did to Carol Danvers that she deserves to be punished for eternity? That's why she a great foil for Wanda in Uncanny Avengers, they both have that in common. Archangel, Wolverine, Jean Grey, Colossus, Gambit, Xavier, Beast have done things that they deeply regret, and Beast is currently doing his finest impression of an amoral CIA spook in X-Force. We'll see whether he regrets his decisions later.
This all goes back to them having problems with Scarlet Witch, which started with Byrne. Read Avengers: Diasssembled, also written by Bendis (who is informed by Byrne's Avengers rather than Busiek's). She-Hulk and Carol Danvers hated her over what she did and as these stories go she wasn't consciously evil she just had a mental breakdown and bad writing to make excuses because they're out of character for Wanda. You need to read Avengers, you don't know what her relationship with them is like.
When have Magik and Emma Frost been punished for their actions? Both never lost their status with the X-men and Magik has been promoted in their ranks once she got her act together. Scott got punished but he remained a lead role in X-men and regained everything, he's not thinking every day of what he did in the P5. That's over for him, not so for Wanda. That defined her ever since.
That the P5 didn't originally want their power shouldn't be an excuse for their actions, while Wanda did sought out the Life Force she was also a victim just like they were. Same symptoms, where it differs is that Wanda lives every day in remorse and society and out of universe fans define her as "bad" while those very same people worship the ground the P5 walk on. Cosmic power overwhelmed both parties but only one is wondered a victim and the other a two dimensional villain.
Look upward, death came for Wanda and she perished. No Death commandos are required.
This idea that every person on Earth, including her closet friends, should shun her for eternity is baffling and contradicts what the X-men do with their own when they fall. You want them to open a hand to their greatest enemies who have caused them more grief than Wanda ever did but want Wanda to suffer without limit. It's hypocritical to the extreme.
This is an excuse to punish an idea of Wanda, not Wanda herself. The attempts to reveal her real character as a hero and that her friends still love and respect her are seen as "attacks." Perhaps this is a holdover from the controversial X-men vs Avengers battles, and Wanda is just a proxy to hate on.
