Why was the scarlet witch hacked?

The crimson witch was blackened because she studied the book of the dark god and longed to save her two children. The book of the dark god was once the source of magic books such as the book of death, which can ensure that you fully understand any language. Although the dark god's schoolbag contains a lot of powerful black magic.

However, its corrupt influence is very strong, and the dwarves in the book of the dark god will also lure people to use the spells recorded in it. After many people use it, the soul will belong to Sision.

In the film, Wanda defeated Agatha with chaotic magic and runes, and thus became a crimson witch. Later, she lifted the enchantment formed by the chaotic magic that enveloped the town, made a farewell to the illusion, bid farewell to Monica Rambo, and left alone. At the end of the film, Wanda's spirit began to learn Agatha's original "The Dark God", and her mind was constantly echoing the cries of children Tommy and Billy for help, thus embarking on the road of blackening.
