@night4345: Doom or not, Wanda was manipulated not only by her own father but Pietro as well. THEY are the ones who nudged her to alter reality and Magneto murdering her brother in that reality is what caused her to lash out. They are to blame not her. Wanda was the gun but they loaded the bullets and pulled the trigger. Magneto always has a way of destroying things/people and coming out hands clean and M-Day was definitely one of those instances.
She wasn't anymore fully responsible than Jean Grey was for the Dark Phoenix incident (funny how people seem to forgive and forget the beloved Emma Frost's role in that huh).
Wanda never pretended to be anything so it doesn't really mirror anything and what is she supposed to do whine about the lives she ruined? Please. You don't see Wolverine doing that and hell, Jean didn't even do that and she killed an entire galaxy's worth of people (duplicate or not - had her memories, soul, and since she's is in fact a part of the Phoenix, it was still her) and why in the world should Wanda.
I guess we just differ in how someone should go about redemption. Say your sorry and move on to actions I say.
