Well, Cyclops used to be a boy scout, Wolverine used to be someone that no one would trust for anything except killing.....................................
And people thinks that i make this of things up................................................ .
That would be an interesting story if we saw it.
I've said it before, "Wanda becomes obsessed with reviving her lost children and winds up destroying herself and the Avengers" isn't an inherently bad story. But it was never written, Bendis just said it happened off-panel and told us to take his word that she'd been going crazy for years. But things that don't happen on-panel simply don't count as much as 40+ years of things that happen on-panel.
We get exactly three flashback panels filling in (aka retconning) what happened in the lead-up to Avengers Disassembled. That's not a story. Whatever I may think about Darker Than Scarlet, it is a story that shows how Wanda goes mad and why. But she's not a character in Avengers Disassembled, it's not her story, and the few panels in Children's Crusade are just an attempt to clean up Bendis's mess a bit (whether you think they succeeded or not is a different matter).
I'm saying fans of the character wouldn't hate Disassembled/HoM as much if we saw her go bad and saw why she went bad. As it is, it was so unmotivated that there was no reason not to simply turn her good again.
I don't remember Scott going to a villain to ask for the Phoenix for himself. And even if he did, it doesn't change one iota Wanda's responsibility in ruining millions of lives and murdering two innocent souls. I don't know how someone could think that "others do it too" is a valid reason to excuse a heinous criminal like the Witch.
The excuse is "the writer didn't treat her fair." "Others do it too" is the in-universe reason why so few characters are mad at her any more, but out of universe it's mostly about "Bendis didn't treat her fair and his stupid story must be retconned."
These aren't real people and they don't have "responsibility" for their actions like real people do. Anything that turns a badly-written character back into a good guy, like possession, is acceptable as long as the end result is better stories. And no one can claim Wanda had better story material when she wasn't in the comics (well, some will claim that, but they're wrong). HoM made her unusable, if it's not her fault she's not usable, therefore it's not her fault. Not hard.
Fine. But the idea that CC makes her an evil baby-crazy self-hating mutant mass-murderer is not, shall we say, universally held. How you interpret that clumsy retcon depends entirely on whether you enjoy hating the character or liking the character. If you want to like the character, it provides all the tools necessary, including the possibility (now pretty much a probability) that Doom planned the whole thing.
