Wanda's character arc in the comics is quite diverse. Sometimes she's portrayed as turning evil due to external influences or internal struggles. However, these depictions can vary greatly depending on the writer and the overall plot of the particular comic series.
It depends on which specific comic arcs you're referring to. In some, she undergoes transformations and makes morally ambiguous choices that could be seen as evil. But in others, her actions have more complex motivations and aren't strictly evil.
